Vyivel a93b18dbd5 input/pointer: send axis source once per frame
Only one wl_pointer.axis_source event is permitted per frame, according
to the Wayland specification.

Simon Ser bcd5d8504c output: remove wlr_output_impl.export_dmabuf
No backend is using it anymore.

Simon Ser 87e8c60faf output: add generic wlr_output_export_dmabuf implementation
When wlr_output manages its own swap-chain, there's no need to
hook into the backend to grab DMA-BUFs. Instead, maintain a
wlr_output.front_buffer field with the latest committed buffer.

Simon Ser 7b25b0ff88 buffer: rename wlr_client_buffer variables to client_buffer
We often juggle between wlr_buffer and wlr_client_buffer variables.
Use a consistent naming: "buffer" for wlr_buffer and "client_buffer"
for wlr_client_buffer.

`wlr_client_buffer_import` is splitted in two distincts function:
	- wlr_buffer_from_resource, which transforms a wl_resource into
	  a wlr_buffer
	- wlr_client_buffer_create, which creates a wlr_client_buffer
	  from a wlr_buffer by creating a texture from it and copying its
	  wl_resource

Simon Ser e035f2b9c4 Fix invalid uses of wl_array_for_each
[1] and [2] have introduced new wl_array usage in wlroots, but
contains a mistake: wl_array_for_each iterates over pointers to
the wl_array entries, not over entries themselves.

Fix all wl_array_for_each call sites. Name the variables "ptr"
to avoid confusion.

Simon Ser b934fbaf04 seat: add wlr_seat_touch_{send,notify}_frame
The wl_touch.frame event is used to group multiple touch events
together. Instead of sending it immediately after each touch event,
rely on the backend to send it (and on the compositor to relay it).

This is a breaking change because compositors now need to manually
send touch frame events instead of relying on wlr_seat to do it.

Simon Ser a48e569d38 output-damage: fix output swapchain handling
When wlr_output.swapchain is used instead of the backend's, the
buffer_type will be set to SCANOUT even if wlr_output_attach_render
has been called. This tricks wlr_output_damage into thinking the
whole output needs to be repainted.

Workaround this issue by forcing buffer_type to RENDER when the
output has a back-buffer set.

Will clean all of that up when removing the precommit event handler
altogether.

This commit fixes damage tracking on the Wayland, X11 and headless
backends.

Simon Ser c2bd63c186 output: detach buffer from renderer before commit
Right now we rely entirely on implicit sync for synchronizing
access to GPU buffers. Implicit sync works by setting
synchronization points on the buffer in writers, and letting
readers wait on these sync points before accessing the buffer.

With OpenGL, sync points are created using functions such as
eglSwapBuffers or glFlush. If none of these special functions
are called, no sync point will be created and readers will
potentially access a buffer that hasn't finished rendering yet.

In the context of wlroots, OpenGL is the writer and the backend
(KMS or parent Wayland/X11 session) is the reader. After we're
done rendering a frame, and before passing that frame to the
backend, we need to call glFlush.

glFlush is called when the buffer is detached from the renderer.
This is a task done by output_clear_back_buffer. So let's call
this function before invoking the impl->commit hook, instead of
calling it after.

All of this is maybe a little tricky to get right with the
current renderer_bind_buffer API. The new
wlr_renderer_begin_with_buffer API is much better, because glFlush
is called on wlr_renderer_end, so it's more intuitive.

Simon Ser e5b5592a95 render: remove wl_drm support from wlr_renderer
Everything needs to go through the unified wlr_buffer interface
now.

If necessary, there are two ways support for
EGL_WL_bind_wayland_display could be restored by compositors:

- Either by using GBM to convert back EGL Wayland buffers to
  DMA-BUFs, then wrap the DMA-BUF into a wlr_buffer.
- Or by wrapping the EGL Wayland buffer into a special wlr_buffer
  that doesn't implement any wlr_buffer_impl hook, and special-case
  that buffer type in the renderer.

Simon Ser d7b19fb294 buffer: handle wl_drm buffers
This allows renderers to choose between implementing the old
wlr_renderer_impl.texture_from_wl_drm hook, or opt for the new
wlr_drm stub. The stub has the advantage of not requiring any
special support code: stubbed wl_drm buffers look exactly like
DMA-BUFs from linux-dmabuf-unstable-v1.

Simon Ser f7e3d325fe Add a stub wl_drm implementation
This will allow us to remove all of our EGL wl_drm support code

particular, wl_drm buffers coming from the EGL implementation
can't easily be wrapped into a wlr_buffer properly.

Simon Ser c7018a45b7 surface: allow locking pending state in commit handler
We were bumping the pending sequence number after emitting the

where current.seq == pending.seq. This prevents commit handlers
from immediately locking the pending state.

Fix this by bumping the pending sequence number before firing the
commit event.

Because the client can destroy the wl_buffer while we still are using
it, we need to do some libwayland tricks to still be able to continue
accessing its underlying storage. We need to reference the wl_shm_pool
and save the data pointer.

Simon Ser 9e58301df7 surface: allow placing subsurfaces below parent
Prior to this commit, subsurfaces could only be placed above their
parent. Any place_{above,below} request involving the parent would
fail with a protocol error.

However the Wayland protocol allows using the parent surface in the
place_{above,below} requests, and allows subsurfaces to be placed
below their parent.

Weston's implementation adds a dummy wl_list node in the subsurface
list. However this is potentially dangerous: iterating the list
requires making sure the dummy wl_list node is checked for, otherwise
memory corruption will happen.

Instead, split the list in two: one for subsurfaces above the parent,
the other for subsurfaces below.

Tested with wleird's subsurfaces demo client.

Simon Ser 76f51a949f xdg-activation-v1: add token timeout
There isn't always a good time to prune old tokens. Compositors
which only implement a "give focus on activation" logic can prune
tokens on focus change. However other compositors might want to
implement other semantics, e.g. "mark urgent on activation". In this
case a focus change shouldn't invalidate other tokens.

Additionally, some tokens aren't necessarily tied to a seat.

To avoid ending up with an ever-growing list of tokens, add a timeout.
