c4253fef9c output: add wlr_output_test_state

25dd3cc0cd output: pass wlr_output_state to backend
Groundwork for the following commits. The goal is to allow users
to specify their own wlr_output_state instead of wlr_output.pending.

be86145322 output: turn make/model/serial into char *
This allows the make/model/serial to be NULL when unset, and allows
them to be longer than the hardcoded array length.

This is a breaking change: compositors need to handle the new NULL
case, and we stop setting make/model to useless "headless" or
"wayland" strings.

cff4abc5b1 output: clear buffer created for test
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.

4377b55292 util/global: remove wl_display arg from wlr_global_destroy_safe
Since [1], we can get the wl_display directly from the wl_global.

e3fefda023 output: add support for protocol interface version 4
Two new events are added: name and description. The name is
immutable. The description can be updated on-the-fly.

36a2b19485 output: introduce wlr_output_set_name
wlroots picks names for all outputs, but it might be desirable for
compositor to override it.

For instance, Sway will use a headless output as a fallback in
case no outputs are connected. Sway wants to clearly label the
fallback output as such and label "real" headless outputs starting
from HEADLESS-1.

efeb8346cf output: drop front_buffer
This lets backends immediately release committed buffers if they
want to.

f016eca97c output: add wlr_output_event_commit.buffer
This allows output commit listeners to access the newly committed
buffer. Currently wlr_output.front_buffer is used but it'll get
removed in the next commit.

697a1cd0f5 output: add wlr_output_get_primary_formats
This allows compositors to get primary formats without manually
calling wlr_output_impl.get_primary_formats.

For example, the Sway patch for linux-dmabuf feedback [1] needs
this.

e879d566bb output: Add function to set preferred render format
This change introduces new double buffered state to the wlr_output,
corresponding to the buffer format to render to.

The format being rendered to does not control the bit depth of colors
being sent to the display; it does generally determine the format with
which screenshot data is provided. The DRM backend _may_ sent higher
bit depths if the render format depth is increased, but hardware and
other limitations may apply.

b2f6ff45c2 output: fix stack variable lifetime in wlr_output_send_present
Variables on the stack are released when the parent block is closed.
Here, `now` is used outside of the `if` block, causing the following
crash when starting Sway with the headless backend:

bf42630d32 output: refuse to enable with zero mode
This can happen if the compositor enables an output without
picking a mode, or performs a modeset with a zero width/height.

fb393ddf84 output: split into multiple files
This organizes the wlr_output implementation into separate files.
This avoids having a single mega-file with lots of unrelated parts
and makes it more obvious what the interactions between all the
parts are.

No functional changes, just moving code around.
