Fixes missing prototypes compilation warnings emitted when a function
is defined before its prototype is declared.
These warnings were introduced over time since the switch to meson
because the -Wmissing-protoypes was not included in the compilation
arguments.

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.

This is preparation for using the weston-debug infrastructure for
WM_DEBUG. dump_property() may be called from different debugging
contexts and often needs to be prefixed with more information.
An alternative to this patch would be to pass in the weston_debug_scope
as an argument to dump_property(), but then all callers would need to be
converted to weston-debug infra in a single commit.
Therefore require the callers to provide the FILE* to print to.

commit e7fff215ad made initializing the
selection_listener conditional, but didn't make its clean-up
conditional at shutdown. Simply initializing the listener's list
link at init time makes this harmless.
To see this, run weston -Bheadless-backend.so and then connect to it
with an X client. When killing weston it will attempt shutdown but
die with a segfault.

weston maintains a copy of the most recently selected "thing" - it picks
the first available type when it copies, and saves that one only.
When an application quits weston will make the saved selection active.
When xwm sees the selection set it will check if any of the offered types
are text. If no text type is offered it will clear the selection.
weston then interprets this in the same way as an application exiting and
causing the selection to be unset, and we get caught in a live lock with
both weston and xwayland consuming as much cpu as they can.
The simple fix is to just remove the test for text presence.

The wrapped weston_data_source struct has new fields which were left
uninitialized, so its access is unreliable.
The data source in xwayland/dnd.c should be eventually setting the
drag-and-drop actions, but it is a lot more incomplete than that
(read: completely), so falls out of the scope of this patch.

This reverts commit d3553c721c.
weston_wm_write_property() takes the ownership of the reply it gets as
a parameter, and will eventually free it later in writable_callback.
This change introduced a double-free when Xwayland programs triggered a
copy to the clipboard, leading to a Weston crash.

Typically we can write it immediately without blocking, so save the overhead
of setting up an fd watch and writing the data in a callback. For the
case where the immediate write doesn't write all data, we fallback and
set up the fd watch as usual.
This patch also consolidates setting up the async write a bit.
Because of its links to selection.c and xwayland, a destroy_signal field
was also added to wl_data_source. Before selection.c and xwayland were
manually initializing the resource.destroy_signal field so that it could be
used without a valid resource.

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.
