We had duplicated code in many places, using hardcoded paths for
temporary files into more than one path. Some cases did not bother with
O_CLOEXEC, and all hardcoded paths that might not exist.
Add an OS helper function for creating a unique anonymous file with
close-on-exec semantics. The helper uses $XDG_RUNTIME_DIR as the
directory for a file.
This patch unifies the buffer file creation in both Weston and the
clients.
As simple clients are better not linking to libshared, as it would
require e.g. Cairo, they pull the OS compatibility code directly.
Android does not have mkostemp(), so a configure test is added for it,
and a fallback used if it is not available.
Changes in v2:
remove all the alternate possible directory definitions and use
XDG_RUNTIME_DIR only, and fail is it is not set.

Previously, simple-shm was rendering an image that looked like stride
gone wrong somewhere, and was quite confusing if you did not know it was
supposed to look like that.
Replace the drawing code. Two circles, inner and outer, now delimit
three co-centric areas. The outmost area from surface borders to outer
circle contains horizontal gradients that move (animate) to the left.
The area between outer and inner circles contains vertical gradients
that move upwards. The center disc has circular gradients moving towards
the center.
The circles are not ellipses.
Diagnostics:
The X-channel is manipulated so, that if a compositor takes the XRGB
image, and uses the X channel as alpha instead of ignoring it, the whole
image will be crossed out by two lines that either quickly saturate to
white or show through with additive blending. Does not work on black
background.

There was a lot of code here to do a lot of work we didn't need to do.
If we damage a surface with a shm buffer attached, all we need to do
is to re-upload the damaged region to the texture. As for drm buffers,
we don't assume anything changes on attach and only update the
regions the client tells us to update in the damage request.
Implement proper destructors that call the wayland destroy functions.
With this and the "client: fix a strdup memory leak" patch in Wayland
core, simple-shm now runs Valgrind-clean (memcheck).

Add signal handler for SIGINT to simple-egl and simple-shm, so they can
be exited voluntarily, without killing them. Later we can add clean-up
code and destructors, and check with valgrind for leaks and errors.

Protocol changes in Wayland core introduced a new interface
wl_shell_surface, and moved all wl_shell surface methods into it. Adapt
the compositor and its Wayland backend, shell plugin, and all clients to
the new interface.
Depends on the Wayland core commit "protocol: introduce wl_shell_surface"
