This will let compositors know if changing adaptive_sync state has any
chance of working. When false, then the current state is the only
supported state, including if adaptive_sync is currently enabled as is
the case for Wayland and X11 backends.
When true, changing state might succeed, but no guarantee is made. It
just indicates that the backend does not already know it to be
impossible.
This commit fixes the following interaction:
1) The host compositor sends a configure sequence for an output.
2) Before handling it, the guest compositor disables and immediately
re-enables the output.
3) The guest compositor tries to ack the configure event from step 1
which isn't relevant anymore after unmapping and re-initialization.
Instead, ignore all configure events after unmapping until we're sure
the host compositor has processed the unmapping.

- Reset all variables representing an initialized xdg_toplevel's state
on unmap.
- Send an initial commit only when an output is about to be enabled.
- If an output isn't configured yet, don't commit a buffer.
It's cumbersome for compositors to guard every
wlr_color_transform_ref() or wlr_color_transform_unref() call
behind a #if WLR_HAS_COLOR_MANAGEMENT. Moreover, none of the LCMS2
types are used in our public API.
Instead, always install the color.h header, and add a stub for
wlr_color_transform_init_linear_to_icc().
Since wlroots almost always significantly breaks API each minor release,
allowing parallel installation of wlroots helps packagers deal with
programs that require conflicting versions of wlroots.

This has been introduced way back in
be297d9d14 but is never used anywhere.
If compositors want to save the old dimensions before reacting to a
fullscreen or maximize event they can just grab the sizes within their
event handlers instead.
This change makes it possible to support both the direct srgb-format
pipeline and indirect (color-managed, or non-srgb-format) pipeline
for the same render buffer.
Instead of having separate getters for shm formats and DMA-BUF
formats, use the same pattern as wlr_output_impl.get_primary_formats
with a single function which takes buffer caps as input.
The surface argument is only used to obtain a wlr_seat_client and
semantically makes no sense. The wl_touch.cancel event applies to all
touch points and all surfaces of a client.
I decided to make the functions accept a wlr_seat_client rather than a
wl_client as it is directly available in the wlr_touch_point struct and
simplifies the implementation.
This is worth doing despite wl_client_get_destroy_listener() incorrectly
accepting a mutable wl_client pointer since this lookup_client()
function will primarily be used with a wl_display_global_filter_func_t
which only provides a const wl_client pointer.
Work around this libwayland API wart in wlroots so compositors don't
have to.
I wish to use a allowlist of globals for my security context
implementation rather than a blocklist, which means I need access to
the wp_single_pixel_buffer_manager_v1 global in order to allowlist it.
I think using a allowlist will make it harder for me to accidentally
expose globals to a security context that were meant to be restricted.

This new helper assists compositors in allocating buffers for
modesets. It degrades to different allocation parameters as
needed, and should help with screens not turning on when multiple
outputs are connected on some hardware (e.g. Intel).
For simplicity, the old logic to try allocating with explicit
modifiers first and then fallback to implicit modifiers later is
left as-is. We'll probably want to have more complicated logic
instead in the future: try the fallback on one output at a time,
and try dropping modifiers one by one instead of using implicit
modifiers (at the cost of some combinatorial explosion).
