Screenshooting does not involve creating a wl_surface, so using struct
surface is superfluous.
Return a struct buffer instead. It could have been just a
pixman_image_t, but setting up proper destruction would be a bit more
work. Should not hurt to keep the wl_buffer around until the user is
ready to free the image.

This rewrites write_surface_as_png() into write_image_as_png(), which
operates on a pixman_image_t instead of a struct surface.
This is part of the migration to use pixman_image_t everywhere without
superfluous parameters/members.
Now the image saving handles more than just ARGB32 format, presumably.
At least it does not assume everything is always ARGB32.

This rewrites load_surface_from_png() to load_image_from_png(), to
return a pixman_image_t instead of a struct surface.
A loaded image has no need for wl_buffer or wl_surface or any of the
associated attributes. This is part of unifying to make everything use
pixman_image_t.
cairo_surface_flush() is added, because Cairo documentation for
cairo_image_surface_get_data() says you have to flush after drawing,
before using the data. It is unclear if loading a PNG counts as drawing,
so stay on the safe side.
load_image_from_png() now pays attention to the pixel format returned by
Cairo, which seems to come out as CAIRO_FORMAT_RGB24 in
internal-screenshot-test, not as CAIRO_FORMAT_ARGB32 as expected. I do
not know if Cairo actually guarantees the x8/a8 channel to be 0xff for
RGB24, but better to not trust it. Therefore the image is explicitly
converted to a8r8g8b8 as needed. This also adds support for loading A8
and RGB16_565 images, provided that Cairo delivers them.
The cairo surface is now wrapped directly into a pixman_image_t. If the
pixel format conversion is not needed, this eliminates a copy of the
image data. The Cairo surface will get automatically destroyed with the
Pixman image.

check_surfaces_geometry() is removed as it was not used by anything, and
unlikely would be.
check_surfaces_equal() is merged into check_surfaces_match_in_clip(),
passing a NULL clip means to compare whole images.
check_surfaces_match_in_clip() is converted to work on pixman_image_t
instead of struct surface. The function is only concerned about
comparing images in memory, and does not care about a wl_buffer or a
wl_surface.
The verbosity of image comparisons is greatly reduced. An image mismatch
no longer prints a flood of raw pixel values. This will be replaced
later with a function writing out an error image instead.
Degenerate comparisons are no longer accepted, be that clip outside
images or zero area. Those are an indication of a programmer error.
The pixel format assumptions are made more visible in the code.
A new internal helper image_check_get_roi() computes and verifies the
area to be compared. Image iterator helper makes it simpler to write
manual pixel-poking loops.

We are growing more tests that need to handle buffers, both just images
and wl_buffers. Particularly the screenshooting facility needs these.
Currently everything is in struct surface, which contains more than we
need. It is a bit messy.
Create a new struct buffer to encapsulate the image representation, the
wl_buffer, and enough information to tear it all down (munmap) so we
don't have to leak everything. Some tests might start doing things in
loops, and leaking would accumulate.
Instead of inventing our own image representation, use pixman_image_t.
It is a well-tested library worth using, and we already rely on it in
other places.
This makes the tests depend on Pixman, which requires the fix for
building buffer-count, which would otherwise not find pixman.h.
The new create_shm_buffer_a8r8g8b8() creates an image with an explicit
format, and pixman_image_t keeps track of it. And stride and size and
data. This implementation is still a little hacky due to calling
create_shm_buffer().
A very new thing is buffer_destroy(). Previously we didn't really free
any buffers. It is not a problem when the process will exit soon anyway,
but it may become a problem if tests start iterating things.
Manual memset() on a image is converted to a pixman action, just to show
how to do it properly with pixman.
Stride and pixel format assumptions still linger all around, but those
are for another patch.

This fix also depends on "compositor-headless: do not create a seat".
If we lose the race against weston-desktop-shell setting cursors, which
is very rare, we get a cursor image in the screenshot, causing the test
to fail. This is now fixed by moving the (remaining) cursor out of the
way.
Arguably we should have better solutions for this, but that is another
story. This is a stop-gap measure we can copy also in new
screenshooting tests.
v2: Remove the example code for how to trigger the race, and rewrite the
big comment.
