723934d0b0 screencast: check if a valid format was received from wlr_screencopy
When a screencast is started we do a roundtrip on get the offered
formats from wlr_screencopy. This roundtrip can fail [1]. In this case
the formats won't be initialized and we will just error out of the
screencast session.

b5491df0c0 screencast: destroy session if output is removed
We teardown all existing screencast_instances using the removed output
by destroying the frame, removing all timers and then marking the
instance as ready for teardown so we can destroy it after the last connected
session is closed.

Any wlr_screencopy_frame_v1 has to be destroyed before the connected
output can be removed. Otherwise wlr_screencopy_frame_v1_destroy
segfaults the whole program. To ensure this we will make all frame
callbacks safe to be triggered for a previous destroyed frame.

ab0a07142d screencast: use wl_array for format-modifier-pairs
wl_array is a better fit than wl_list. It's less intensive on memory and
fits nicely with the flow of dmabuf_feedback announcing all format
modifier pairs at once and reseting them on change.

2219db7508 screencast: use dmabuf_feedback
The compositor can announce it's default rendering device via
linux_dmabuf_feedback as the main_device [1]. We should use this device
whenever possible. If aquiring this device fails we are adviced to use
force linear layout on buffers allocated with the implicit api.

With linux_dmabuf_v1 the modifier event is deprecated. Instead the
format_table event in combination with the tranches of
linux_dmabuf_feedback_v1 has to be used.

14852efb05 screencast: Remove MESA hack from the old gbm api fallback
Calling gbm_bo_create_with_modifiers2(...) and setting the modifiers
pointer to NULL for the same result as gmb_bo_create(...) is a MESA hack,
which I missed to remove from 84282e9b5f.

29f86168b6 screencast: announce supported explicit modifiers
We query the supported modifiers via a wrapper and announce them via
PipeWire.

This wrapper queries the supported formats from wlroots and returns them
as a simple array. The purpose of this wrapper is to ease the use of the
query functions which are kept in the style of the equivalent egl
queries.

2ca2b7b603 screencast: get supported format modifier pairs from wlroots
Registering a zwp_linux_dmabuf_v1_listener gives access to the supported
format modifier pairs of the compositor.

This handler emits events for each format modifier pair. Those are stored
and will later be used to announce capabilities via PipeWire.

b9c4472c50 screencast: stop assuming that allocation with implicit modifier works
It has shown that the assumption: "Allocation with implicit modifier will
always be available" doesn't hold true in all cases. Thus if allocation
of any dmabuf fails we mark the session to avoid dmabufs, thus falling
back to shm transport.

84282e9b5f screencast: fixate modifier from PipeWire format negotiation result
This implements the modifier fixation procedure. The producer of a
stream has to ensure that it can create a buffer with the negotiated
properties. To do that we will take the result of the intersection of
supported modifiers by PipeWire and select the "best" modifier from that
list.

To do this we do the following allocations and fixate on the
modifier of the created buffer should the allocation suceed.
* Try to allocate a buffer with explicit modifiers using the list
  provided by PipeWire
* Walk the list of modifiers and do single allocations for implicit and
  linear modifiers using the old api.

If none of the allocations above succeed we fall back to shm buffers.
This is implemented in the next commit.

If an allocation was successfull we fixate the modifier with
fixate_format().
This function creates an EnumFormat like build_format, but will only
announce support for a single modifier.
It is used to finish the negotiation process by announcing it together
with EnumFormats of our full supported formats.

a70a1195d4 screencast: check if pipewire returns a modifier list
Using SPA_POD_PROP_FLAG_DONT_FIXATE pipewire can return a list of
supported modifiers. In that case are we responsible to select one
modifier and fixate it.

5799adeb57 screencast: enqueue pipewire when screencopy failed
Keeping a buffer when the copy failed has the risk of having this buffer
removed while we wait for the next buffer_done event. To prevent this we
just enqueue the buffer marking it as corrupt. A new buffer will be
dequeued at the buffer_done event.

2f32d17448 screencast: remove swap_buffer function
Dequeuing a new buffer imidiately creates a problem when the buffer is
destroid while renegotiation of a valid modifier because we can end up using
a buffer which was freed while waiting for the buffer_done event. Then
xdpw will segfault when requesting a copy with a nonexisting buffer. To fix
this we can just dequeue a buffer right before we need it. This makes
the fallback via on_process obsolete since we dequeue the buffer at the
lates possible time.

6cec421f92 screencast: improve logging for pipewire events
We should log buffer add and remove events in the debug loglevel, since
they signal starts, stops and renegotiations of the buffer transfer.
Additionaly logging the negotiated pwr_format should help classify
issues from the DEBUG loglevel.

852e1c95c7 screencast: HACK set an arbitrary chunk size for dmabufs
Clients have wrongly used the chunk size to detect if a buffer was valid
or not. Since dmabufs might not have a well defined buffer size we will
set an arbitrary value until clients are patched.

0683f7ca7e screencast: add option to force implicit modifier to be linear
Linear buffer layouts are supported by most gpu vendors and as such
should be compatible in mixed mutli gpu setup where the implicit
modifier of one gpu is not supported by the other.

This option should make xdpw work in these environemnts.

The option is marked as experimental since it might be removed if
explicit modifiers provide a better solution.

bae393a684 screencast: support modifiers in build_format
When announcing support for dmabufs via PipeWire this is done by adding
the SPA_FORMAT_VIDEO_modifier property to an EnumFormat. Producers can
choose between two different ways [1]:

* Supporting only implicit modifiers by adding the property as a sigle
  value together with the SPA_POD_PROP_FLAG_MANDATORY flag
* Support for multiple modifiers. This is done by announcing a
  SPA_CHOICE_ENUM array together with the use of the
  SPA_POD_PROP_FLAG_MANDATORY and SPA_POD_PROP_FLAG_DONT_FIXATE flag

12de0cd144 screencast: introduce buffer_type
We want to support WL_SHM and DMABUFS based buffers. The buffer_type
member tracks the type of a xdpw_buffer and screencopy_frame_info of the
screencast_instance will be an array with an element for each buffer type
indexed by the value of the buffer_type enum. Only members of the
xdpw_screencopy_frame_info relevant to the buffer type should be used.
