* protocols: add Fifo-v1
introduce fifo-v1
* fifo: only present locked surfaces
dont present to unlocked surfaces and commit pending states from the
fifo protocol.
* fifo: cformat
cformat
* protocols: add committiming and surface state queue
introduce CSurfaceStateQueue and commit-timing-v1
* fifo: schedule a frame if waiting on barrier
if we are waiting on a barrier the state doesnt commit until the next
refresh cycle meaning the monitor might have no pending damage and we
never get onPresented to unlock the barrier, moment 22. so schedule a
frame.
* fifo: properly check monitor intersection
check for m_enteredoutputs or monitor intersection if client hasnt bound
one yet, and dont fifo lock it until the surface is mapped.
* buffer: try to merge states before committing them
try to merge states before committing them meaning way less churn and
surface commits if a surface sends multiple small ones while we wait for
buffer readyness from either fifo locks or simply fences.
* buffer: dont commit states past the buffer
certain changes are relative to the buffer attached, cant go beyond it
and apply those onto the next buffer.
* buffer: set the lockmask directly
cant use .lock since the state hasnt been queued yet, set the lockmask
directly when exporting buffer fence.
* fifo: dont fifo lock on tearing
dont fifo lock on tearing.
* buffer: queue the state directly
queue the state directly and use the .lock function instead of directly
modify the lockMask on the state.
* buffer: revert creating texture at commit time
fifo barriers introduces such long wait that upon commit time a
race happends with current xdg configure implentation that the buffer
and image is actually destroyed when entering commitState, doing it at
buffer creation time with EGL_PRESERVED_KHR means it sticks around until
we are done. so revert 82759d4 and 32f3233 for now.
* buffer: rename enum and lockreasons
eLockReason and LOCK_REASON_NONE.
* fifo: workaround direct scanout lock
workaround cursor commits causing fifo to get forever locked, this
entire thing needs to be worked out.
* buffer: move texture creation to commit time
move creating texture away from buffer attach into commitstate in an
attempt to postpone gpu work until its really needed. best case scenario
gpu clocks have ramped up before because we are actively doing things
causing surface states and a commit to happend meaning less visible lag.
* buffer: simplify texture creation
make createTexture return a shared ptr directly, remove not needed
member variables as m_success and m_texture.
* compositor: make pending states store frame callbacks
move frame callbacks to pending states so they are only committed in the
order they came depending on the buffer wait for readyness.
* buffer: damage is relative to current commit
ensure the damage is only used once, or we are constantly redrawing
things on state commits that isnt a buffer.
thanks PlasmaPower.
* compositor: move callbacks back to compositor
move SSurfaceStateFrameCB back to compositor in the class
CWLCallbackResource as per request, but still keep the state as owning.
* compositor: ensure commits come in order
if a buffer is waiting any commits after it might be non buffer commits
from the "future" and applying directly. and when the old buffer that
was waiting becomes ready it applies its states and overwrites the
future changes.
move things to scheduleState and add a m_pendingWaiting guard. and
schedule the next pending state from the old buffer commit when done.
and as such it loops itself and keeps thing orderly.

use unique pointers and rvalue references where applicable, buffer is
still a shared pointer because CHLBufferReference uses it to hold it
locked.
in CSHMPool destructor add a check for m_data != MAP_FAILED same in
resize, because mmap returns (void *) -1 on failure and that is not
comparable to nullptr. delete default constructor so we dont end up in
weird states with m_data.
* dmabuf: disable buffer read check on intel
readability checks directly on buffer fds on some intel laptops is
broken, see https://gitlab.freedesktop.org/drm/intel/-/issues/9415
* sync: use rvalue ref in addwaiter doonreadable
use rvalue reference in addwaiter and doonreadable, because we store the
function in the SReadableWaiter a lot of the time, move it into place
there when that happends or let it go out of scope after function call.
* add doOnReadable to event loop manager
* move syncTimeline addWaiter to doOnReadable
* wait on dmabuf buffers to be readable
* don't over synchronize in scanout, also give present feedback on same buffer commit
* make CHLBufferReference not a SP anymore
* copy over release and acquire points in CHLBufferReference
* use CHLBufferReference in screencopy and toplevel export
TODO: use CHLBufferReference in direct scanout properly
the only problem is the scanout buffer release timing,
specifically the onBackendRelease mechanism
* cleanup SSurfaceState and surface pending commit tracking
* move surface code from DRMSyncobj, and move acquire to SSurfaceState
* use queue for comitted pending surface states like proto says
"The content update is placed in a queue until it becomes active." - wl_surface::commit
* drop, not release, prev buffer if 2nd buffer wl_surface.attach is sent
"A wl_buffer that has been attached and then replaced by another attach instead of committed will not receive a release event, and is not used by the compositor." - wl_surface::attach
