This adds a destroy listener on the SHM buffer provided by our client.
It will unregister the frame notify listener in case our buffer is
destroyed before the frame signal is emitted and thus avoid a memcpy
to invalid memory.

(cherry picked from commit 0afd3428dc899c426d37650192f828541f70e390)
Everywhere we are standardising to drm_fourcc.h pixel format codes, and
using struct pixel_format_info as a general handle that allows us to
access the equivalent format in various APIs. In the name of
standardisation, convert weston_compositor::read_format to
pixel_format_info.
Pixman formats are defined CPU-endian, while DRM formats are defined
always little-endian. OpenGL has various definitions. Correctly mapping
between these when the CPU is big-endian is an extra chore we can
hopefully offload to pixel-formats.c.
GL-renderer read_format is still defined based on Pixman format, because
of the pecualiar way OpenGL defines a pixel format with
GL_UNSIGNED_BYTE. That matches the same Pixman format on big-endian but
not the same drm_fourcc.

When we first see a buffer attached, we create a weston_buffer for it.
The weston_buffer doesn't contain any useful information in and of
itself; that's left to renderers to populate later.
Switch this to doing it in the core at the first opportunity, at least
for SHM and dmabuf buffers; EGL buffers will follow in the next commit.

If full output damage is forced every time a screenshot is taken, the
test suite cannot take screenshots of damage as that would depend on
repainting only the damaged area.
Stop damaging the output and instead just schedule a repaint so the
screenshot can be taken. This is safe because:
- if any views were promoted to hw planes previously,
weston_output_disable_planes_incr() would force them to be demoted at
assing_planes() time causing damage via weston_view_move_to_plane()
- even when hardware primary plane has no damage, DRM-backend will not
skip calling to the renderer after commit
"drm-backend: do not skip renderer if capturing screen".

Instead of getting previous_damage from the weston_output struct, get it from

The member disable_planes of weston_output signifies the recording
status of the output, and is incremented and decremented from various
places. This patch provides helper functions to increment and decrement
the counter. These functions can then be used to do processing, before
and after the recording has started or stopped.

The printf() format specifier "%m" is a glibc extension to print
the string returned by strerror(errno). While supported by other
libraries (e.g. uClibc and musl), it is not widely portable.
In Weston code the format string is often passed to a logging
function that calls other syscalls before the conversion of "%m"
takes place. If one of such syscall modifies the value in errno,
the conversion of "%m" will incorrectly report the error string
corresponding to the new value of errno.
Remove all the occurrences of the specifier "%m" in Weston code
by using directly the string returned by strerror(errno).
While there, fix some minor indentation issue.

The main idea is to make libweston users use the form
#include <libweston/libweston.h>
instead of the plain
#include <compositor.h>
which is prone to name conflicts. This is reflected both in the installed
files, and the internal header search paths so that Weston would use the exact
same form as an external project using libweston would.
The public headers are moved under a new top-level directory include/ to make
them clearly stand out as special (public API).

Normally we need to check if a seat's [device_type]_count is > 0 before
we can use the associated pointer. However, in a binding you're
guaranteed that the seat has a device of that type. If we pass in
that type instead of the seat, it's obvious we don't have to test it.
The bindings can still get the seat pointer via whatever->seat if they
need it.
This is preparation for a follow up patch that prevents direct access
to seat->device_type pointers, and this will save us a few tests at
that point.

An error makes the client exit, which cleans up the resources anyway.
Note (Jason Ekstrand):
This is safe for two reasons. First, we should be handling object
destruction nicely anyway. Second, in each of these cases, the resources
don't have any implementation or destruction set so it has absolutely no
effect on the rest of weston whether we destroy it now or later.
Most zalloc calls in weston are checked, this fixes a handful that were

If the compositor hasn't been rendering for a while when the recording

This wraps all accesses to an SHM buffer between wl_shm_buffer_begin
and end so that wayland-shm can install a handler for SIGBUS and catch
attempts to pass the compositor a buffer that is too small.
This commit sets the version numbers for all added/created objects. The
wl_compositor.create_surface implementation was altered to create a surface
with the same version as the underlying wl_compositor. Since no other
"child interfaces" have version greater than 1, they were all hard-coded to
version 1.

AC_USE_SYSTEM_EXTENSIONS enables _XOPEN_SOURCE, _GNU_SOURCE and similar
macros to expose the largest extent of functionality supported by the
underlying system. This is required since these macros are often
limiting rather than merely additive, e.g. _XOPEN_SOURCE will actually
on some systems hide declarations which are not part of the X/Open spec.
Since this goes into config.h rather than the command line, ensure all
source is consistently including config.h before anything else,
including system libraries. This doesn't need to be guarded by a
HAVE_CONFIG_H ifdef, which was only ever a hangover from the X.Org
modular transition.
