Previously weston_config_section_get_uint was serving dual purpose for
parsing both unsigned decimal integer values (ids, counts, seconds,
etc.) and hexadecimal values (colors), by relying on strtoul's
auto-detection mechanism.
However, this usage is unable to catch certain kinds of error
conditions, such as specifying a negative number where an unsigned
should be used. And for colors in particular, it would misparse hex
values if the leading 0x was omitted. E.g. "background-color=99999999"
would render a near-black background (effectively 0x05f5e0ff) instead of
medium grey, and "background-color=ffffffff" would be treated as an
error rather than white. "background-color=0x01234567",
"background-color=01234567", and "background-color=1234567" each
resulted in the value being parsed as hexadecimal, octal, and decimal
respectively, resulting in colors 0x01234567, 0x00053977, and 0x0012d687
being displayed.
This new routine forces hexadecimal to be used in all cases when parsing
color values, so "0x01234567" and "01234567" result in the same color
value, "99999999" is grey, and "ffffffff" is white. It also requires
exactly 8 or 10 digits (other lengths likely indicate typos), or the
value "0" (black).

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.

Degenerate comparisons are no longer accepted, be that clip outside

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.
