If we get an authenticated primary node from the X11 server, don't use
it because we can't authenticate our Wayland clients with it. Instead,
open a render node.

This callback allowed compositors to customize the EGL config used by
the renderer. However with renderer v6 EGL configs aren't used anymore.
Instead, buffers are allocated via GBM and GL FBOs are rendered to. So
customizing the EGL config is a no-op.
The Present protocol states:
> An event context is associated with a specific window; using an existing
> event context with a different window generates a Match error.
Instead of a global event context, use a per-window event context to fix
this error:
[backend/x11/backend.c:608] X11 error: op Present (SelectInput), code Match (no extension), sequence 63, value 4194307
Closes: https://github.com/swaywm/wlroots/issues/2577
We queried DRI3 formats, but we weren't using them. Because of a typo,
only render formats were used.

This reverts commit 3317134adf.
This reverts commit a3c3b928a3.
There are some serious issues when running this on a real X server, as
opposed to running this on Xwayland, where this was tested.
More investigation needs to be done into why these issues happen and if
our usage of the present extension is correct.
Makes use of the present extension to get notified of vsync, and not
require any stupid timer hacks. Also make use of the present version of
ConfigureNotify, because why not?
The documentation for wayland-server.h says:
> Use of this header file is discouraged. Prefer including
> wayland-server-core.h instead, which does not include the server protocol
> header and as such only defines the library PI, excluding the deprecated API
> below.
Replacing wayland-server.h with wayland-server-core.h allows us to drop the
WL_HIDE_DEPRECATED declaration.
This updates the backend part of the output API. This is mostly renaming:
make_current becomes attach_render and swap_buffers becomes commit.
This also fixes the RDP backend to support NULL damage.
Otherwise running under Xvfb will not deliver any events. This results
in e.g. weston-info reporting a 0x0 window size (which results in all
sorts of problems).
Compositors now have more control over how the backend creates its
renderer. Currently all backends create an EGL/GLES2 renderer, so
the necessary attributes for creating the context are passed to a
user-provided callback function. It is responsible for initializing
provided wlr_egl and to return a renderer. On fail, return 0.
Fixes#987
When the X11 server sends an expose event, that means that "this
rectangle here (the event contains x,y,width,height) has undefined
contents on your window; please redraw that". This means that we need a
swap. However, so far the code does not actually enforce that a swap
happens.
For example, start rootston, switch to another workspace and then switch
back. The rootston window will not be redrawn (before commit
52b058c2a3, it would just be fully white; after that commit it will
show whatever was visible on the old workspace). This is because the
drawing code concludes that nothing needs to be done. However, in fact a
swap is necessary.
This reverts commit e79d924588, because its optimisation is already
done now: wlr_output_update_needs_swap() emits a signal, which is
handled by wlr_output_damage with a call to wlr_output_schedule_frame().
This function does nothing if a frame is already pending. Thus, the
optimisation from commit e79d924588 now happens implicitly.

When resizing rootston with the mouse, the result is really slow. One
can see that rootston needs quite a while for drawing the newly visible
area. This is because every single expose event is handled on its own
and causes (apparently) a full repaint or at least a swap.
This commit improves things by only causing a new frame if none is
pending already.
With this change, there is almost no delay in rootston drawing the newly
visible area.

handle_x11_event() and x11_handle_input_event() react to different kinds
of events, so it does not make much of a difference if
x11_handle_input_event() signals if it handled an event or not.

The xcb_connection_t instance that is used here comes from
XGetXCBConnection(), is created by XOpenDisplay(), and is owned by the
returned Display*. Calling xcb_disconnect() directly on it leads to
various use-after-frees during shutdown, as reported by valgrind. The
first one of the about 30 errors is:

Normally, one would expect this to crash during XCloseDisplay() when
xcb_disconnect() is called again and frees the same data again (glibc would
detect a double free). However, XCloseDisplay() tries to clean up some internal
caches first for which it has to send requests to the X11 server (e.g. the
XFreeGC() above). This fails since the file descriptor was already closed,
which causes an IO error. Xlib's _XDefaultIOError() handles this by printing an
error message and calling exit(1).
Thus, the only symptom of this problem was compositors exiting
mid-shutdown and printing an error message:
XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
after 6 requests (6 known processed) with 0 events remaining.

The backend destroy signal is emitted before the output_remove
signal is. When the destroy signal is emitted listeners remove
their output_remove listener, so the output_remove signal is never
received and listeners have an invalid output pointer.
The correct way to solve this would be to remove the output_remove
signal completely and use the wlr_output.events.destroy signal
instead. This isn't yet possible because wl_signal_emit is unsafe
and listeners cannot be removed in listeners.
This backports some changes to #319 to fix the screenshooter data
format. This also adds wlr_backend_get_renderer which will be
useful to support multiple renderers.
In pointer.c, some axis event was emitted even if the event pointer did not have
current axis.
In X11 backend pointer scroll events seem to be composed of both BUTTON_PRESS
and BUTTON_RELEASE. Therefore we should skip one of them (RELEASE) to avoid
event duplication.
