We have two functions with the name weston_screenshooter_shoot():
1. screenshot protocol function that the screenshooter
client uses to request screenshots to the compositor
2. libweston function used by the compositor to take
screenshots as requested by the screenshooter client
Until now we had no problem with that, but in the next commits
we are going to use the screenshot protocol in the test suite,
which is also user of libweston. So rename screenshot protocol
function to weston_screenshooter_take_shot() to avoid the conflict.
For consistency, also rename screenshooter_shoot() to
screenshooter_take_shot() in compositor/weston-screenshooter.c

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.

As is stands now, libexec/weston-screenshooter can only be called from
within weston server. This will allow weston-screenshooter to be called
on the command line. The final scope here is to allow taking screenshots
without the need of a keyboard.

Instead of overwriting the 'wayland-screenshot.png' file over and
over, store each requested screenshot in a filename based on timestamp
and sequence number.

weston-screenshooter is a helper binary that weston launches to write the
screenshot to disk. If somebody tries to launch it by hand, print a
warning and mention the screenshot keybinding.
All the clients here were missing the global_remove handler. Because
window.c did not have it, weston-desktop-shell and weston-keyboard
segfaulted on compositor exit, as they received some
wl_registry.global_remove events.
Add more or less stub global_remove handlers, so that clients do not
crash on such events. Toytoolkit and all applications would need a lot
more code to properly handle the global object removal.

This is a workaround for screenshots with transformed outputs. It reorders
the output positions so the correct buffer size is determined for the final
image. This assumes the outputs are in succession on the x axis. The outputs
are rendered in their transformed state.
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.
