We can't safely close the output part of the I/O stream until any
pending write or flush has been completed. In the worst case, this could
lead to an assertion failure in the worker (when the close wins the
race) or not closing the stream at all (when the write wins the race).

num_writes_pending was a counter, but it only took values 0 or 1, so make
it a boolean: it would never make sense to be trying to write out two
messages at the same time (they'd get interleaved).
Similarly, we can never be writing and flushing at the same time (that'd
mean we were flushing halfway through a message, which would be pointless)
so combine it with flush_pending too, calling the result output_pending.
Also assert that it takes the expected value whenever we change it,
and document the locking discipline used for it, including a subtle
case in write_message_in_idle_cb where it's not obvious at first glance
why we don't need the lock.
(Having the combined boolean at the top of the block of write-related
struct members improves struct packing on 64-bit platforms, by packing
read_num_ancillary_messages and output_pending into one word.)

Add an extra state pointer and an extra GDestroyNotify function
to the 'Chunk' definition... allowing bindings to attach some extra
state to memory chunks (to get memory management correctly from
language bindings).
Bug #589887
The GApplication test case tried to fork() while using GMainLoop,
causing problems. Avoid doing that by splitting the child process into
a separate program and spawning it in the usual way.

The 'key' variable is no longer valid outside the cycle, owned and
probably already freed by GVariant. This causes apps to segfault
when proxy is constructed and a property on remote d-bus service
changes (actually is invalidated). Looks like a typo anyway.

* Do not ignore the system default
* Do not exclude the last used being set from the default list
This fixes the default applications dialog in control-center.

Historically we've added random symbols to the public API with warnings
that they're private; examples are:
glib_gettext(), glib_pgettext()
g_thread_functions_for_glib_use, g_thread_use_default_impl, etc.
And we almost added "GWakeup" to public API just to share between glib and
gio.
This new glib__private__() API exports a hidden vtable, and adds a macro
GLIB_PRIVATE_CALL() that makes it generally convenient to use.
This adds an extremely tiny cost for the double indirection; but it has
the benefit that we don't need to either:
1) compile the code into both glib and gio (like GWakeup), with the
inefficiency that implies.
2) Export a "do not use this" symbol; the serious problem with this is
that someone CAN use it pretty easily. Particularly if we document
it. It's far, far harder to peek into a structure without a public
header file.

g_thread_gettime() is an undocumented public function pointer that
points to a function that returns the monotonic time in nanoseconds.
g_get_monotonic_time() does the same in microseconds, so it can be used
instead.
GLib had one internal user in GFileMonitor that only cared about
millisecond accuracy; it has been ported to g_get_monotonic_time().
In particular, remove the libasyncns import, which was only used by
GUnixResolver, which is only used when threads are not available.
Likewise remove GWin32Resolver, and the hacky broken non-threaded
parts of GIOScheduler.

G_THREADS_ENABLED still exists, but is always defined. It is still
possible to use libglib without threads, but gobject (and everything
above it) is now guaranteed to be using threads (as, in fact, it was
before, since it was accidentally impossible to compile with
--disable-threads).

Non-technical users won't know that "stating" refers to stat(2), so we
just use "error when getting information" now.

When g_settings_apply() is called on a delayed settings backend and
there is a D-Bus error when communicating with dconf-service, recent
versions of the dconf GSettingsBackend call a function in GLib that
improperly delivered the signal directly instead of using
g_main_context_invoke().
This patch fixes this function to route in the same way as the others so
that the signal is dispatched in the proper GMainContext.
- getmntinfo can take struct statfs or statvfs depending on the
OS. Use getvfsstat and if not found getfsstat instead. Idea from
Dan Winship.
- g_local_file_query_filesystem_info(): use statvfs.f_fstypename
if available

The threaded tests are using the default main context in the worker
thread, but were not g_main_context_acquire()ing it first, which meant
that g_tls_interaction_invoke_ask_password() in the main thread would
sometimes succeed in acquiring it itself and thus performing the
operation in the wrong thread. Fix that.
Also, we can't unref the loop from the worker thread, because the main
thread isn't holding a reference on it, and so it might end up being
destroyed while that thread is still inside g_main_loop_quit().
(which shouldn't ever have been part of the API. Grr.)
Solaris /etc/services doesn't even have "http", which was causing
tests/network-address to fail...
On Solaris, getsockname() on an unconnected socket gives an addrlen of
0 and doesn't set the sockaddr. So use the SO_DOMAIN sockopt to find
the socket family in that case. (SO_DOMAIN doesn't exist everywhere,
so we can't use it unconditionally. Also, we have to only use it if
getsockname() fails, since SO_DOMAIN returns a bogus value for
accept()ed sockets on both Linux and Solaris...)
Also, link libgio to -lresolv explicitly, rather than depending on
getting it implicitly via the libasyncns build (which should
eventually be going away).

* Add 'invoke' style method, which can be used to call an interaction
from any thread. The interaction will be run in the appropriate
#GMainContext
* Sync methods can be called whether main loop is running or not.
* Derived classes can choose to implement only sync or async
interaction method, and the invoke method will fill in the blanks.
* Documentation for the above.
* Tests for the above.

g_desktop_app_info_set_as_default_for_type() and
g_desktop_app_info_set_as_last_used_for_type () require the
application's ID, but depending on how the GAppInfo was created,
we might not be have one, and would thus silently fail to set
the default application, or last used application.

The test was using a socket in a temporary directory, but not actually
creating that temporary directory. This worked fine on Linux since it
actually ended up using an abstract socket instead, but failed on
unixes without abstract sockets.
