The previously documented requirements for implementing init() and
init_async() as completely idempotent were really quite hard to achieve,
and brought a lot of pain for very little gain. Many implementations of
GInitable and GAsyncInitable did not actually follow the requirements,
or did not correctly handle concurrent init_async() calls.
Relax those requirements so that classes can decide whether their init()
or init_async() implementations need to be idempotent.

This is effectively the mc-wait-for-name tool from
telepathy-mission-control; moving it in to gdbus-tool will make it more
widely useful without making people depend on telepathy-mission-control
for no other reason. The code here is reimplemented from scratch to use
GDBus.
It blocks until the specified well-known name is owned by some process
on the bus (which can be the session, system, or any other bus). By
passing --activate, the same (or a different) name can be auto-started
on the bus first.
A timeout can be specified to ensure the process doesn’t block forever.

This will help us break generic GType deadlocks between people using
GDBus in different threads (which is supported), not just by GType
usage in the GDBus thread.
This should fix the common cases we're seeing in the wild, although I
have some lingering concerns that if someone e.g. referenced
e.g. `G_TYPE_DBUS_AUTH_MECHANISM_SHA1` etc. we'd need to add those
too.

We currently assume that the OpenURI portal should be used
unconditionally when running inside a flatpak sandbox. While
the portal is what we usually want, there are exceptions:
Yelp is now included in the GNOME runtime to allow displaying
help without exporting the user documentation, and the sandboxed
app itself may register a scheme handler.
To account for those cases transparently, always try the normal
code path first and only fall back to calling the portal when
that fails.

These calls cause race warnings from tsan, but are not a thread safety
problem, because we can only ever observe single bit changes: all
modifications to the GSource.flags field are done with a lock held; all
reads are of independent fields, so no intermediate state can ever be
observed. This assumes that a non-atomic read will consistently give us
an old value or a new value.
In any case, these g_source_is_destroyed() calls can happen from any
thread, and the state could be changed from another thread immediately
after the call returns; so the checks are pointless. In addition,
calling g_source_set_ready_time() or g_source_destroy() on a destroyed
source is not a problem.
https://bugzilla.gnome.org/show_bug.cgi?id=778049
Calling the D-Bus method for the OpenURI portal "protects" the logic from
not ever having the remote method running in case the xdg-desktop-portal
process is not yet running and the caller quits quickly after the call.
This should not be a problem as the method returns immediately (regardless
of the user making a selection), but making it synchronous would prevent
situations where the OpenURI method would never be called because of D-Bus
dropping the message after the caller dies, without explicitly waiting for
a reply.

Actually, Unicode changes to this file got reverted in

g_subprocess_launcher_spawn() is NULL-terminated, and must have a

Previously, _kh_cancel_sub assumed that it only needed to call
_km_remove if sub did not exist in subs_hash_table. This is erroneous
because the complementary operation, _km_add_missing, can be called
from process_kqueue_notifications, in which context sub can *only* have
come from subs_hash_table.
Since _km_remove is implemented using g_slist_remove, which is
documented to be a noop if the list does not contain the element to be
removed, it is safe to call _km_remove unconditionally here.

On the warning/critical error handling paths for g_settings_set(), the

Spotted while running `make check` under Valgrind. While it’s not
necessary to fix memory leaks in glib-compile-schemas (since it’s a
utility which runs briefly then exits), fixing them makes more
legitimate leaks in the Valgrind output more obvious, and means we can
be sure there aren’t leaks in the underlying GLib/GIO code which
glib-compile-schemas is calling.

We're first getting the notification by its notify_id, but activating

Fix this by simply searching the list of active notifications again

GNOME Builder's code was assuming that setting the launcher's
environ to NULL makes the subprocess have an empty environment, but in
fact the parent process's variables are still inherited because execv is
used instead of execve when envp is NULL. This commit clarifies the
documentation to make the behavior clear.

This is small enough that it shouldn't cause problems on most machines
we support, but big enough to increase throughput on a lot of devices

It was suggested that the project files be moved here as we don't actually
need to go two directory layers from $(srcroot), and would help us to
standardize on things in the future across the board.
When performing the verify and building the error string there were two
possibilities of an infinite loop. The first is the missing twos-complement
to unset the bit in the filtered flags. The second is the lack of handling
G_SUBPROCESS_FLAGS_NONE which can return a valid GFlagsValue (and cannot
unset the bit since the value is zero).
This walks all known values in the GSubprocessFlags type class and check
if they are set. This has the benefit that we don't call needless functions
which walk the same table as well as avoiding mutating values to build
the error string.

WSAWaitForMultipleEvents() only returns for one of the waiting threads, and
that one might not even be the one waiting for the condition that changed. As
such, only let a single thread wait on the event and use a GCond for all other
threads.
With this it is possible to e.g. have an UDP socket that is written to from
one thread and read from in another thread on Win32 too. On POSIX systems this
was working before already.

glibc string.h declares memcpy() with attribute(nonnull(1,2)), causing
calls with NULL arguments to be treated as undefined behaviour.
This is consistent with ISO C99 and C11, which state that passing 0
to string functions as an array length does not remove the requirement
that the pointer to the array is a valid pointer.
gcc -fsanitize=undefined catches this while running OSTree's test suite.
Similarly, running the GLib test suite reports similar issues for
qsort(), memmove(), memcmp().

If we have an input parameter (or return value) we need to use (nullable).
However, if it is an (inout) or (out) parameter, (optional) is sufficient.
It looks like (nullable) could be used for everything according to the
Annotation documentation, but (optional) is more specific.
If g_socket_receive_message_with_timeout() is called with messages ==
NULL set the msg_control buffer to empty to not request the control
messages from recvmsg() at all.
This completely disables the control message processing and reduces
overhead, which might be critical at high packet rate.
