Rework subcompositor damage culling and use a back buffer in the pict renderer
Note that the EGL renderer has been broken by these changes.
* compositor.h (struct _RenderFuncs): Change arguments to
`finish_render'. Add `cancel_completion_callback'. Remove
`cancel_presentation'.
(struct _BufferFuncs): Add `is_buffer_opaque'.
* egl.c: Note that the EGL renderer is currently broken.
* fence_ring.c (FenceFree, struct _Fence, GetFence, FenceAwait)
(FenceToXFence): Repurpose fence code as a generic allocator of
fences.
* frame_clock.c (EndFrame): Adjust calculation of even value.
* picture_renderer.c (struct _BufferActivityRecord): Remove
`fence'.
(struct _PictureBuffer): Remove unused field.
(struct _PresentCompletionCallback): Remove unused fields
linking it to the target.
(struct _BackBuffer): New structure.
(IsBufferBusy, SetBufferBusy, ClearBufferBusy): New macros.
(struct _PictureTarget): Add back buffer and GC fields.
(use_sync_fences): Remove variable.
(RecordBufferActivity): Don't take fence.
(UnlinkActivityRecord): Don't wait on fence.
(FreeBackBuffer, FreeBackBuffers, CreateBackBuffer)
(MakePresentationCallback, SwapBackBuffers)
(SwapBackBuffersWithCopy, MaybeAwaitBuffer, GetNextBackBuffer)
(EnsurePicture): New functions.
(TargetFromDrawable): Don't create picture for window targets,
and create GC for those.
(NoteTargetSize): Free back buffers instead of creating
presentation windows.
(DestroyRenderTarget): Free back buffers.
(ViewContainsExtents): Delete function.
(FinishRender): Swap back buffers and handle callbacks.
(CancelCompletionCallback): New function.
(TargetAge): Implement accordingly.
(PresentToWindow, CancelPresentationCallback): Present to the
regular window instead of a separate ``presentation window''.
(CancelPresentation): Remove function.
(picture_render_funcs): Add CancelCompletionCallback; remove
NeverAges and CancelPresentation.
(BufferFromDmaBuf, FinishDmaBufRecord, BufferFromShm): Set
opaque flag accordingly.
(IsBufferOpaque): New function.
(picture_buffer_funcs): Add IsBufferOpaque.
(HandlePresentCompleteNotify, HandlePresentIdleNotify): Handle
back buffer release.
* renderer.c (RenderFinishRender, RenderCancelCompletionCallback)
(RenderCancelPresentation, RenderIsBufferOpaque): Adjust
accordingly.
* seat.c (InterpolateAxes): Fix NULL-pointer dereference.
* subcompositor.c (SetFrozen, IsFrozen): Get rid of unused
state.
(struct _View): Cache the width and height. Add cull_region
field.
(struct _Subcompositor): Add `render_key' field.
(ViewAfterSizeUpdate): Set cached width and height.
(ViewAttachBuffer): Correctly handle size changes.
(ViewDamage): Apply buffer damage.
(ViewDamageBuffer): use ViewDamage.
(ApplyBufferDamage): New function.:(FillBoxesWithTransparency,
ViewContainsExtents, IntersectBoxes): Delete unused functions.
(RenderCompletedCallback): New function.
(NoViewsAfter): Delete function.
(SkipSlug): New slug.

(DoCull, DrawBackground, CompositeSingleView, InitBackground)
(SubcompositorComposite1, SubcompositorComposite): New
functions. Implement new redisplay logic here.
(SubcompositorUpdate, CopyRegion): New function.
(SubcompositorExpose, SubcompositorFree): Clear render callback
if set.
(SubcompositorLookupView): Use cached width and height.
(SubcompositorFreeze, SubcompositorUnfreeze): Remove unused
functions.
