wayland_output_destroy_shm_buffers() is called immediately before
output_destroy() of the renderer is called. And for the pixman renderer all
renderbuffers must be destroyed before the output can be destroyed.
Also, weston_renderbuffer_unref() is not called when the buffer is released
because buffer->output is now NULL, so the renderbuffer would be leaked.
So just unref the renderbuffer immediately. Set it to NULL to avoid unreffing it
again should wayland_output_destroy_shm_buffers() be called again before the
buffer is released. This can happen during an xdg-shell resize.

The pixel format stored in backends->format[0] is effectively looked up
via pixel_format_get_info(DRM_FORMAT_ARGB8888). Reuse that instead of
looking up the same via pixel_format_get_info_by_pixman(PIXMAN_a8r8g8b8)

There are still two instances of hard-coded CAIRO_FORMAT_ARGB32 in
wayland_output_get_shm_buffer() that currently can not be obtained from
pixel_format_info.

This changes the GL-renderer interface to pass the initial framebuffer
size and compositing area explicitly. All backends are changed to
provide the correct parameters.
GL-renderer mostly does not yet use these values, but later patches
will. The pbuffer path uses it already, because they replaced the
existing fields.
All this is to make GL-renderer aware of the different sizes, so it can
implement the future revision of the screenshooting API.

In a journey to decouple renderer from weston_output, pass the initial
framebuffer size to Pixman-renderer explicitly.

Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>
Previously renderers were not told when the output (framebuffer they
need to draw) size changed. Renderers just pulled that information out
from weston_output::current_mode when they happened to need it. This
makes some things awkward, like resizing the shadow or intermediate
buffers. In fact, Pixman-renderer does not even support resizing its
shadow buffer, nor does GL-renderer. DRM-backend has to destroy and
re-create the renderer output state anyway, but rdp, x11 and wayland
backends would be natural users of resizing API.
This commit adds an API for resizing with empty implementations. Actual
implementations will be added in following patches for each renderer
while moving parts of resizing code from backends into the renderers.
No-op renderer needs no implementation.
Only wayland-backend has actual resizing code already, and that is made
to call the new API. Unfortunately, Pixman and GL renderers differ: one
does not blit them while the other does. In order to assert the
functionality of each renderer to keep the API consistent,
wayland-backend needs to lie to pixman-renderer. That's not new, it
already does so in wayland_output_get_shm_buffer() where the 'pm_image'
addresses only the interior area instead of the whole buffer.

As wayland-backend is blitting the output decorations into the output
buffer itself, it pretends towards the pixman-renderer that there is no
decorations area. The pixman_image_create_bits() call wraps the
previously allocated buffer with an offset so that pixman-renderer will
paint in the right position.
The bug is that this pixman image was using the original buffer width
and height, instead of the composited area width and height. So the
pixman image looks too big to pixman-renderer, but the renderer didn't
care. The image being too big does risk access out of bounds in
pixman-renderer.
I found this when I was making renderers explicitly aware of the
frambuffer size and resizing, added asserts, and they surprisingly
failed. This fixes that.

A following patch is going to need the introduced 'area' and 'fb_size'
variables. Until then though, a little hack is needed to avoid no-gl
builds failing with error: variable 'fb_size' set but not used.
While starting to use struct weston_geometry, convert also the input and
opaque regions to use it. This shortens and simplifies the code, as we
can drop the roughly duplicate code of doing stuff for with vs. without
a frame.
No change in behavior, this is pure refactoring.

The repaint_data is entirely backend specific. Moreover, it is only used by the
drm backend, while other backends ignore the repaint data.
There will always be only one repaint active, thus, there is no need to pass the
repaint data from the outside.
The repaint_data breaks with the multi-backend series, which calls repaint begin
for all backends to get the repaint_data. The repaint_data of the last backend
will then be passed to all other backend. At the moment, this works, because the
drm backend is the only backend that implements the begin_repaint call.
Another option would be to track the repaint data per backend in the compositor,
but actually, it the backend needs to track state across the calls, it's its own
responsibility.
