Prepare arrange code for type safe arguments This commit changes the arrange code in a way that will support type safe arguments. The arrange_output et al functions are now public, however I opted not to use them directly yet. I've kept the generic arrange_windows there for convenience until type safety is fully implemented. This means this patch has much less risk of breaking things as it would otherwise. To be type safe, arrange_children_of cannot exist in its previous form because the thing passed to it could be either a workspace or a container. So it's now renamed to arrange_children and accepts a list_t, as well as the parent layout and parent's box. There was some code which checked the grandparent's layout to see if it was tabbed or stacked and adjusted the Y offset of the grandchild accordingly. Accessing the grandparent layout isn't easy when using type safe arguments, and it seemed odd to even need to do this. I determined that this was needed because a child of a tabbed container would have a swayc Y matching the top of the tab bar. I've changed this so a child of a tabbed container will have a swayc Y matching the bottom of the tab bar, which means we don't need to access the grandparent layout. Some tweaks to the rendering and autoconfigure code have been made to implement this, and the container_at code appears to work without needing any changes. arrange_children_of (now arrange_children) would check if the parent had gaps and would copy them to the child, effectively making the workspace's gaps recurse into all children. We can't do this any more without passing has_gaps, gaps_inner and gaps_outer as arguments to arrange_children, so I've changed the add_gaps function to retrieve it from the workspace directly. apply_tabbed_or_stacked_layout has been split into two functions, as it had different logic depending on the layout. Lastly, arrange.h had an unnecessary include of transaction.h. I've removed it, which means I've had to add it to several other files.

Implement type safe arguments and demote sway_container This commit changes the meaning of sway_container so that it only refers to layout containers and view containers. Workspaces, outputs and the root are no longer known as containers. Instead, root, outputs, workspaces and containers are all a type of node, and containers come in two types: layout containers and view containers. In addition to the above, this implements type safe variables. This means we use specific types such as sway_output and sway_workspace instead of generic containers or nodes. However, it's worth noting that in a few places places (eg. seat focus and transactions) referring to them in a generic way is unavoidable which is why we still use nodes in some places. If you want a TL;DR, look at node.h, as well as the struct definitions for root, output, workspace and container. Note that sway_output now contains a workspaces list, and workspaces now contain a tiling and floating list, and containers now contain a pointer back to the workspace. There are now functions for seat_get_focused_workspace and seat_get_focused_container. The latter will return NULL if a workspace itself is focused. Most other seat functions like seat_get_focus and seat_set_focus now accept and return nodes. In the config->handler_context struct, current_container has been replaced with three pointers: node, container and workspace. node is the same as what current_container was, while workspace is the workspace that the node resides on and container is the actual container, which may be NULL if a workspace itself is focused. The global root_container variable has been replaced with one simply called root, which is a pointer to the sway_root instance. The way outputs are created, enabled, disabled and destroyed has changed. Previously we'd wrap the sway_output in a container when it is enabled, but as we don't have containers any more it needs a different approach. The output_create and output_destroy functions previously created/destroyed the container, but now they create/destroy the sway_output. There is a new function output_disable to disable an output without destroying it. Containers have a new view property. If this is populated then the container is a view container, otherwise it's a layout container. Like before, this property is immutable for the life of the container. Containers have both a `sway_container *parent` and `sway_workspace *workspace`. As we use specific types now, parent cannot point to a workspace so it'll be NULL for containers which are direct children of the workspace. The workspace property is set for all containers, except those which are hidden in the scratchpad as they have no workspace. In some cases we need to refer to workspaces in a container-like way. For example, workspaces have layout and children, but when using specific types this makes it difficult. Likewise, it's difficult for a container to get its parent's layout when the parent could be another container or a workspace. To make it easier, some helper functions have been created: container_parent_layout and container_get_siblings. container_remove_child has been renamed to container_detach and container_replace_child has been renamed to container_replace. `container_handle_fullscreen_reparent(con, old_parent)` has had the old_parent removed. We now unfullscreen the workspace when detaching the container, so this function is simplified and only needs one argument now. container_notify_subtree_changed has been renamed to container_update_representation. This is more descriptive of its purpose. I also wanted to be able to call it with whatever container was changed rather than the container's parent, which makes bubbling up to the workspace easier. There are now state structs per node thing. ie. sway_output_state, sway_workspace_state and sway_container_state. The focus, move and layout commands have been completely refactored to work with the specific types. I considered making these a separate PR, but I'd be backporting my changes only to replace them again, and it's easier just to test everything at once.

Implement type safe arguments and demote sway_container This commit changes the meaning of sway_container so that it only refers to layout containers and view containers. Workspaces, outputs and the root are no longer known as containers. Instead, root, outputs, workspaces and containers are all a type of node, and containers come in two types: layout containers and view containers. In addition to the above, this implements type safe variables. This means we use specific types such as sway_output and sway_workspace instead of generic containers or nodes. However, it's worth noting that in a few places places (eg. seat focus and transactions) referring to them in a generic way is unavoidable which is why we still use nodes in some places. If you want a TL;DR, look at node.h, as well as the struct definitions for root, output, workspace and container. Note that sway_output now contains a workspaces list, and workspaces now contain a tiling and floating list, and containers now contain a pointer back to the workspace. There are now functions for seat_get_focused_workspace and seat_get_focused_container. The latter will return NULL if a workspace itself is focused. Most other seat functions like seat_get_focus and seat_set_focus now accept and return nodes. In the config->handler_context struct, current_container has been replaced with three pointers: node, container and workspace. node is the same as what current_container was, while workspace is the workspace that the node resides on and container is the actual container, which may be NULL if a workspace itself is focused. The global root_container variable has been replaced with one simply called root, which is a pointer to the sway_root instance. The way outputs are created, enabled, disabled and destroyed has changed. Previously we'd wrap the sway_output in a container when it is enabled, but as we don't have containers any more it needs a different approach. The output_create and output_destroy functions previously created/destroyed the container, but now they create/destroy the sway_output. There is a new function output_disable to disable an output without destroying it. Containers have a new view property. If this is populated then the container is a view container, otherwise it's a layout container. Like before, this property is immutable for the life of the container. Containers have both a `sway_container *parent` and `sway_workspace *workspace`. As we use specific types now, parent cannot point to a workspace so it'll be NULL for containers which are direct children of the workspace. The workspace property is set for all containers, except those which are hidden in the scratchpad as they have no workspace. In some cases we need to refer to workspaces in a container-like way. For example, workspaces have layout and children, but when using specific types this makes it difficult. Likewise, it's difficult for a container to get its parent's layout when the parent could be another container or a workspace. To make it easier, some helper functions have been created: container_parent_layout and container_get_siblings. container_remove_child has been renamed to container_detach and container_replace_child has been renamed to container_replace. `container_handle_fullscreen_reparent(con, old_parent)` has had the old_parent removed. We now unfullscreen the workspace when detaching the container, so this function is simplified and only needs one argument now. container_notify_subtree_changed has been renamed to container_update_representation. This is more descriptive of its purpose. I also wanted to be able to call it with whatever container was changed rather than the container's parent, which makes bubbling up to the workspace easier. There are now state structs per node thing. ie. sway_output_state, sway_workspace_state and sway_container_state. The focus, move and layout commands have been completely refactored to work with the specific types. I considered making these a separate PR, but I'd be backporting my changes only to replace them again, and it's easier just to test everything at once.

Introduce default seatop This introduces a `default` seat operation which is used when no mouse buttons are being held. This means there is now always a seat operation in progress. It allows us to separate `default` code from the standard cursor management code. The sway_seatop_impl struct has gained callbacks `axis`, `rebase` and `end`, and lost callbacks `finish` and `abort`. `axis` and `rebase` are only used by the default seatop. `end` is called when a seatop is being replaced by another one and allows the seatop to free any resources, though no seatop currently needs to do this. `finish` is no longer required, as each seatop can gracefully finish in their `button` callback. And `abort` is not needed, as calling `end` would achieve the same thing. The struct has also gained a bool named allow_set_cursor which allows the client to set a new cursor during `default` and `down` seatops. Seatops would previously store which button they were started with and stop when that button was released. This behaviour is changed so that it only ends once all buttons are released. So you can start a drag with $mod+left, then click and hold right, release left and it'll continue dragging while the right button is held. The motion callback now accepts dx and dy. Most seatops don't use this as they store the cursor position when the seatop is started and compare it with the current cursor position. This approach doesn't make sense for the default seatop though, hence why dx and dy are needed. The pressed_buttons array has been moved from the sway_cursor struct to the default seatop's data. This is only used for the default seatop to check bindings. The total pressed button count remains in the sway_cursor struct though, because all the other seatops check it to know if they should end. The `down` seatop no longer has a `moved` property. This was used to track if the cursor moved and to recheck focus_follows_mouse, but seems to work without it. The logic for focus_follows_mouse has been refactored. As part of this I've removed the call to wlr_seat_keyboard_has_grab as we don't appear to use keyboard grabs. The functions for handling relative motion, absolute motion and tool axis have been changed. Previously the handler functions were handle_cursor_motion, handle_cursor_motion_absolute and handle_tool_axis. The latter two both called cursor_motion_absolute. Both handle_cursor_motion and cursor_motion_absolute did very similar things. These are now simplified into three handlers and a single common function called cursor_motion. All three handlers call cursor_motion. As cursor_motion works with relative distances, the absolute and tool axis handlers convert them to relative first.

However, it's worth noting that in a few places places (eg. seat focus and transactions) referring to them in a generic way is unavoidable which is why we still use nodes in some places. If you want a TL;DR, look at node.h, as well as the struct definitions for root, output, workspace and container. Note that sway_output now contains a workspaces list, and workspaces now contain a tiling and floating list, and containers now contain a pointer back to the workspace. There are now functions for seat_get_focused_workspace and seat_get_focused_container. The latter will return NULL if a workspace itself is focused. Most other seat functions like seat_get_focus and seat_set_focus now accept and return nodes. In the config->handler_context struct, current_container has been replaced with three pointers: node, container and workspace. node is the same as what current_container was, while workspace is the workspace that the node resides on and container is the actual container, which may be NULL if a workspace itself is focused. The global root_container variable has been replaced with one simply called root, which is a pointer to the sway_root instance. The way outputs are created, enabled, disabled and destroyed has changed. Previously we'd wrap the sway_output in a container when it is enabled, but as we don't have containers any more it needs a different approach. The output_create and output_destroy functions previously created/destroyed the container, but now they create/destroy the sway_output. There is a new function output_disable to disable an output without destroying it. Containers have a new view property. If this is populated then the container is a view container, otherwise it's a layout container. Like before, this property is immutable for the life of the container. Containers have both a `sway_container *parent` and `sway_workspace *workspace`. As we use specific types now, parent cannot point to a workspace so it'll be NULL for containers which are direct children of the workspace. The workspace property is set for all containers, except those which are hidden in the scratchpad as they have no workspace. In some cases we need to refer to workspaces in a container-like way. For example, workspaces have layout and children, but when using specific types this makes it difficult. Likewise, it's difficult for a container to get its parent's layout when the parent could be another container or a workspace. To make it easier, some helper functions have been created: container_parent_layout and container_get_siblings. container_remove_child has been renamed to container_detach and container_replace_child has been renamed to container_replace. `container_handle_fullscreen_reparent(con, old_parent)` has had the old_parent removed. We now unfullscreen the workspace when detaching the container, so this function is simplified and only needs one argument now. container_notify_subtree_changed has been renamed to container_update_representation. This is more descriptive of its purpose. I also wanted to be able to call it with whatever container was changed rather than the container's parent, which makes bubbling up to the workspace easier. There are now state structs per node thing. ie. sway_output_state, sway_workspace_state and sway_container_state. The focus, move and layout commands have been completely refactored to work with the specific types. I considered making these a separate PR, but I'd be backporting my changes only to replace them again, and it's easier just to test everything at once.

Introduce default seatop This introduces a `default` seat operation which is used when no mouse buttons are being held. This means there is now always a seat operation in progress. It allows us to separate `default` code from the standard cursor management code. The sway_seatop_impl struct has gained callbacks `axis`, `rebase` and `end`, and lost callbacks `finish` and `abort`. `axis` and `rebase` are only used by the default seatop. `end` is called when a seatop is being replaced by another one and allows the seatop to free any resources, though no seatop currently needs to do this. `finish` is no longer required, as each seatop can gracefully finish in their `button` callback. And `abort` is not needed, as calling `end` would achieve the same thing. The struct has also gained a bool named allow_set_cursor which allows the client to set a new cursor during `default` and `down` seatops. Seatops would previously store which button they were started with and stop when that button was released. This behaviour is changed so that it only ends once all buttons are released. So you can start a drag with $mod+left, then click and hold right, release left and it'll continue dragging while the right button is held. The motion callback now accepts dx and dy. Most seatops don't use this as they store the cursor position when the seatop is started and compare it with the current cursor position. This approach doesn't make sense for the default seatop though, hence why dx and dy are needed. The pressed_buttons array has been moved from the sway_cursor struct to the default seatop's data. This is only used for the default seatop to check bindings. The total pressed button count remains in the sway_cursor struct though, because all the other seatops check it to know if they should end. The `down` seatop no longer has a `moved` property. This was used to track if the cursor moved and to recheck focus_follows_mouse, but seems to work without it. The logic for focus_follows_mouse has been refactored. As part of this I've removed the call to wlr_seat_keyboard_has_grab as we don't appear to use keyboard grabs. The functions for handling relative motion, absolute motion and tool axis have been changed. Previously the handler functions were handle_cursor_motion, handle_cursor_motion_absolute and handle_tool_axis. The latter two both called cursor_motion_absolute. Both handle_cursor_motion and cursor_motion_absolute did very similar things. These are now simplified into three handlers and a single common function called cursor_motion. All three handlers call cursor_motion. As cursor_motion works with relative distances, the absolute and tool axis handlers convert them to relative first.

Implement type safe arguments and demote sway_container This commit changes the meaning of sway_container so that it only refers to layout containers and view containers. Workspaces, outputs and the root are no longer known as containers.

In addition to the above, this implements type safe variables. This means we use specific types such as sway_output and sway_workspace instead of generic containers or nodes.
