In !863 I assumed that a 4 byte wchar_t would be equal to gunichar on all platforms,
but this is not the case for FreeBSD. It previously was using the non wchar_t based API
because it doesn't define __STDC_ISO_10646__.
Add back the __STDC_ISO_10646__ check again and introduce a more meaningful macro for guarding
the code paths that are mixing gunichar and wchar_t.

It should produce a generic result, but not crash. It was previously
crashing on macOS.

This was introduced in commit 7846d6154a: g_subprocess_get_identifier()
will return NULL after the subprocess has exited, and the subprocess in
the `noop` test will exit as soon as it has started spawning. So if the
scheduler scheduled the testprog subprocess quickly, descheduled the
parent test process until the testprog exited, then the return value
from g_subprocess_get_identifier() would be NULL.
Move the g_subprocess_get_identifier() test to one which calls testprog
in `sleep-forever` mode, since that is guaranteed not to exit until
killed (which we do later in the test).

The documentation erroneously said that a thread calling
g_rw_lock_reader_lock() would always block if another thread was waiting
for the write lock. That’s not true: if no thread holds the lock, it is
implementation defined which of a waiting reader and writer gets the
lock.

The most useful ones were already listed in the pkg-config file, but
some others (notably, `gio-querymodules`) were not. List them in the
pkg-config file with their installed paths so that the right binary is
used if GIO is installed in a non-default path.

`NM_STATE_CONNECTED_SITE` is documented to mean that a default route is
available, but that the internet connectivity check failed. A default
route being available is compatible with the documentation for
GNetworkMonitor:network-available, which should be true if the system
has a default route for at least one of IPv4 and IPv6.

More vectors will give an error and we can simply clamp here and
consider it like a short write instead.
In case of GSocketOutputStream this is done here instead of inside
GSocket before calling sendmsg() because we we can't generically handle
short writes when sending messages on a socket, e.g. for datagram
sockets this causes only part of the datagram to be sent and an error
would be more useful in this case than sending corrupted data.
Also reduce the fallback limit to 16 in gsocket.c as that's the minimum
value required by POSIX and add a static assertion that the limit is
never bigger than G_MAXINT as that's the type recvmmsg/sendmmsg take.
These have all been documented as deprecated for a long time, but we’ve
never had a way to programmatically mark them as deprecated. Do that
now.

The definitions weren’t templated in glibconfig.h.in at all, so didn’t
vary between configurations of GLib — so they should be in a normal
header.

This allows the symbols there to be used conditionally, depending on the

When defining deprecated macros, annotate them with
`GLIB_DEPRECATED_MACRO_IN_*()` and `GLIB_DEPRECATED_MACRO_IN_*_FOR()` to
conditionally emit warnings if people use them, depending on their
declared minimum and maximum GLib version requirements (see
`GLIB_VERSION_MIN_REQUIRED` and `GLIB_VERSION_MAX_ALLOWED`).
The old way of doing this was for users to define `G_DISABLE_DEPRECATED`
if they didn’t want to use deprecated APIs, but it reported errors via
missing symbols, and wasn’t version-dependent. It’s being phased out.

These will be used to annotate deprecated macros, types and enumerators.
`GLIB_DEPRECATED_MACRO{,_FOR}` are based very heavily on the
corresponding macros from Clutter, written by Emmanuele Bassi.
The other deprecation annotators use the standard annotations supported
by Clang and GCC. They need to be separated as they are supported in
different versions of the compilers.

lconv 1.13 only supports gcc <=7 and lcov 1.14 supports <=8.
msys2 was just updated to gcc9, so this wont help with coverage support, but
it's a start I guess.
Queries the charset used by the associated console, which does not
necessarily match the charset of the current locale as returned by
g_get_charset.
Fixes https://gitlab.gnome.org/GNOME/glib/issues/1270
As we discovered in GNOME/gtk#1280, GCC considers the pragmas to control
the deprecation warnings as statements. This means we cannot just use
the GLib wrappers as markers around the call site, but we must be aware
of their side effects.
Let's document this, to avoid falling into the trap.
