19cd57d4f3 GCancellable: use GCond and GMutex directly
Use a statically-allocated GCond and directly use GMutex instead of
making use of the undocumented G_LOCK_NAME() macro.

34ce4dd032 Replace static privates by privates
GStaticPrivate is heading for deprecation soon, and GPrivate
can replace these uses now.

cf26a6fc32 G_LOCK: port from GStaticMutex to GMutex
GCancellable made use of the undocumented G_LOCK_NAME macro in an
invalid way.  Fix that up while we're at it.

9bf59d4a14 Add glib__private__() API to share between glib,gio; port GWakeup to it
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.

5a30712dc7 Remove !g_thread_supported() codepaths in gio
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.

54579bf88f gio: GCancellable can be used concurrently
* Update documentation to note that GCancellable can be used
   concurrently by multiple operations.
 * Add documentation to g_cancellable_reset that behavior is
   undefined if called from within cancelled handler.
 * Add test for multiple concurrent operations using the same
   cancellable.

fa87399280 GCancellable: Use Linux eventfd() instead of pipe
See commit f626dd2b4311bd82137c5b208ab2de288c3e6fae for rationale;
basically it's cheaper than a pipe.

b74e2a720a Stop using glib-genmarshal at build time
To help cross compilation, don't use glib-genmarshal in our
build.  This is easy now that we have g_cclosure_marshal_generic().

In gobject/, add gmarshal.[ch] to git (making the existing entry
points stubs).

In gio/, simply switch to using g_cclosure_marshal_generic().

6181c7de36 GCancellable: add g_cancellable_create_source()
g_cancellable_create_source() returns a GSource that triggers when its
corresponding GCancellable is cancelled. This can be used with
g_source_add_child_source() to add cancellability to a source.

Port gasynchelper's FDSource to use this rather than doing its own
cancellable handling, and also fix up its callback argument order to
be more normal.

ced88fd0de Bug 585189 – g_cancellable_reset() must be called in same thread ...
... as g_cancellable_cancel()
Rework a g_critical() that would (rarely) trigger when _reset() was
called in a thread different from _cancel() by making _reset() wait for
the cancel function to be finished the same way
g_cancellable_disconnect() uses.

e10edefff1 Simplify GCancellable support on win32
There is no need to have a GIOChannel in the GPollFD in
g_cancellable_create_pollfd. All we need is an Event object that
we signal when cancelling and reset when resetting.

Also, supporting g_cancellable_get_fd on Windows using _pipe is useless
as it doesn't work with any corresponding poll() function, so just don't
support that on win32.

I tested this with the cancellation support in GSocket from gnio.

7f4864e58d Bug 505361 - gunixinputstream.c assumes poll() available
Bug 509446 - portable blocking gio cancellation

	* gcancellable.c (g_cancellable_make_pollfd): New method to make a
	GPollFD for a cancellable (which is slightly more complicated on
	Windows than Unix).

	* gunixinputstream.c (g_unix_input_stream_read):
	* gunixoutputstream.c (g_unix_output_stream_write): Use
	g_cancellable_make_pollfd() and g_poll() rather than using poll()
	directly.

	* tests/unix-streams.c: test of GUnixInputStream,
	GUnixOutputStream, and GCancellable.
