This removes an artificial limitation in form of an assert that disallowed the
creation of textures while the renderer is rendering.
A consumer might run its own rendering pipeline and after start of the renderer
still want to create textures for internal usage.
To be consistent with other wlr_xdg_* structs,
wlr_xdg_positioner_resource is renamed to wlr_xdg_positioner and made
public, and wlr_xdg_positioner is renamed to wlr_xdg_positioner_rules.
Functions which operated on wlr_xdg_positioner were renamed and updated
accordingly.
In case the `wlr_input_device` is not owned by a specialized input device, the
function will finish the wlr_input_device and call it's implementation destroy
function if an implementation has been supplied, or simply free it.
When calling wlr_output_test an empty buffer might be created. This implicitly
changes the pending state of the output. Ensure that such a change is only
temporarily and clear such an empty buffer before returning the test result.
wlroots doesn't really follow the rule of keeping `create`/`destroy` and
`init`/`finish` functions in pairs, so the relevant doc section is
updated accordingly.
I am running a custom compiled version of chromium with a patch to get
it up and running on sway git at the moment, and in that development
build I compiled there is a bug where the browser will crash if you
try to open a file select dialog. When this crash happens, chromium will
not close, but instead will remain open and impossible to close unless
you send a SIGKILL signal to the process. However, sway will crash to
tty when you send the SIGKILL.
I have a hunch that when chromium is opening the file select dialog
it is creating some sort of a xdg toplevel surface. But it freezes
before it fully initializes the surface. When the SIGKILL signal is
given, sway/wlroots will try to free the xdg_toplevel surface but
because it hasn't fully initialized due to the frozen window, it
segfaults.
Don't be fooled by the assert, the assert is not firing, the surface
pointer is indeed NULL here.

The wlroots APIs currently don't allow importing/uploading a buffer
during rendering operations. Scene-graph buffer nodes need to turn
their wlr_buffer into a wlr_texture at some point. It's not always
possible to do so at wlr_scene_buffer creation time because the
scene-graph may have zero outputs at this point, thus no way to
grab a wlr_renderer.
Instead, add scene-graph buffers to a pending list and try to import
them in wlr_scene_output_commit.

Commit 498f30aad1 changed the logic of
get_mapping() in types/wlr_cursor.c to use updated version of
wlr_output_layout_get_box(). However, the case where c_device isn't NULL
but doesn't have output or geometry mappings wasn't handled properly,
resulting in leaving the output value uninitialized. This commit fixes
`c_device != NULL` branch by returning from the function only when a
mapping is found.
