There was a theoretical deadlock between the worker trying to emit a
signal at the same time as we were waiting for it to shutdown the
notification (while holding the lock).
The deadlock was particularly annoying because we didn't really need to
wait for the shutdown and because it wasn't possible to signals to
arrive while waiting for a start. Attempting to deal with start and
stop in an asymmetric way could have lead to other weird situations,
however.
Drop the lock while waiting for the worker thread to start. This means
that we face the possibility of multiple waiters on the cond at the same
time, so we need to make more of a state machine.

GUnixMountMonitor was not threadsafe before. It was a global singleton
which emitted signals in the first thread that happened to construct it.
Move it to a per-context singleton model where each GMainContext gets
its own GUnixMountMonitor. Monitor for the changes from the GLib worker
thread and dispatch the results to each context with an active monitor.

Deprecate g_unix_mount_monitor_set_rate_limit() and turn it into a
no-op.
This function doesn't behave as advertised. It only controls rate
limiting for filesystem-based monitors. It has no impact over reporting
mount changes on Linux, for example, because those are based on polling
for changes in /proc (which doesn't use filesystem monitors). It also
has no impact on Mac OS because a library interface is used there.
This was added in https://bugzilla.gnome.org/show_bug.cgi?id=521946 in
order to be used by HAL, which is effectively dead. udisks no longer
uses this code at all.

This is a singleton, but we have a function called _new() to get it.
What's worse is that the documentation makes no mention of this, and
actually specifically says that a new monitor will be created each time.

Add a new internal helper called GContextSpecificGroup.
This is a mechanism for helping to maintain a group of context-specific
monitor objects (eg: GAppInfoMonitor, GUnixMountMonitor).

If someone explicitly calls g_application_quit() then don't attempt to
drain the mainloop of remaining sources.
This allows applications with 100% CPU utilisation to quit reliably.

We install win32-software/autorun.exe (as test data for mime scanning)
only on UNIX builds, so don't attempt to chmod it on 'make install'
unless we're on UNIX.
This is pure read-only access to an external struct
so void warnings for people calling it from const
contexts such as accessors

switching to the old macros boilerplate to G_DECLARE_*
a lot of warnings start to pop when *_IS_A_* or such are
called from a const context.
Fix this by taking const pointers as parameters

I love Emacs keyboard macros, used them to convert the list of
defines cleverly into a list of tests, then iterated and filled in
the necessary constructor arguments.
- It's not sufficient, there are other bare array types
like guint8, gdouble, etc.
- Other types like GVariant* always come as pointers, whereas
there's a rather fundamental distinction between "gchar" and
"gchar*" that has been signified to C programmers for 30+ years via
the '*' character, and we're hiding that.

The g_autoptr() being associated with the type name works out really
well for things like GHashTable. However, it's a bit more awkward to
associate with "gchar". Also because one can't use "char".
Similarly, there are a lot of other "bare primitive array" types that
one might reasonably use.
This patch does not remove the autoptr for "gchar", even though I
think it's rather awkward and strange.
Also while we're here, add a test case for the cleanup bits.

After ::shutdown, run the mainloop until all pending activity is
handled, before returning from run().
Among other things, this gives a chance for destroyed windows to be
properly withdrawn from the windowing system.

This is *significantly* more pleasant to use from C (while handling
errors and memory cleanup).
While we're here, change some ugly, leaky code in
tests/desktop-app-info.c to use it, in addition to a test case
in tests/file.c.

g_application_bind_busy_property() had the restriction that only one
property can be bound per object, so that NULL could be used to unbind.
Even though this is enough for most uses, it is a weird API.
Lift that restriction and add an explicit unbind function.

Add an implementation of non-thread-emulated async close of a GIOStream
if either of the underlying stream objects support it.
This prevents us from calling close() functions from another thread on
an object that may not be expecting that. It also allows us to skip the
thread entirely in case our objects support a pure async close.
https://bugzilla.gnome.org/show_bug.cgi?id=741630
Add an internal helper to find out if close_async() is implemented via
threads using the default implementation in the base class.
We will use this to decide if we should do a 'pure async' close of a
GIOStream or not.

delayed_close_free() calls g_object_unref() on a variable that is
expected to possibly contain NULL (as indicated by the fact that the
NULL case is handled in my_slow_close_output_stream_close_async()).
This is dead code right now (due to a bug in GDBus), which is why it
isn't actually causing a failure. It should still be fixed, however.

GApplication set the prgname to the application's id when it was running
in service mode. This broke with the addition of new --app-id option,
because g_set_prgname() was called before parsing the options. Calling
it after option parsing doesn't work, because GOptionContext sets
prgname to argv[0] unconditionally.
Instead of changing the semantics of GOptionContext, simply remove this
functionality from GApplication. It is very unusual to have the prgname
set to the app id instead of the binary's name and might confuse people
when looking at logs etc.
When overriding local_command_line() from a subclass,
g_option_context_parse() might never be invokded. Thus, continue setting
the prgname to argv[0] in GApplication.
