Reimplement gioscheduler in terms of GTask, and deprecate the original
gioscheduler methods. Update docs to point people to GTask rather than
gioscheduler and GSimpleAsyncResult, but don't actually formally
deprecate GSimpleAsyncResult yet.

GThreadPool defaulted to 0 for max_unused_threads (meaning thread-pool
threads would exit immediately if there was not already another task
waiting for them), and 0 for max_idle_time (meaning unused threads
would linger forever, though this is only relevant if you changed
max_unused_threads).
However, GIOScheduler changed the global defaults to 2 and 15*1000,
respectively, arguing that these were more useful defaults. And they
are, so let's use them.

* GCancellable can be "cancelled" more than once if
g_cancellable_reset() is called.
* Don't assume that because the "cancelled" signal fired
it won't fire again.

In general, code using g_slist_delete_link() is broken, because it
potentially requires an O(n) traversal. Just switch to GList in this
case.
The performance hit here was exacerbated by the fact that we were
holding a mutex that needed to be accessed by all threads.

Add g_main_context_ref_thread_default(), which always returns a
reffed GMainContext, rather than sometimes returning a (non-reffed)
GMainContext, and sometimes returning NULL. This simplifies the
bookkeeping in any code that needs to keep a reference to the
thread-default context for a while.

The GIOScheduler was using a GCond in a way that didn't deal with the
possibility of spurious wakeups. Add an explicit predicate and a loop.

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.

GFile allows for the possibility that external implementations may not
support thread-default contexts yet, via
g_file_supports_thread_contexts(). GVolumeMonitor is not yet
thread-default-context aware.
Add a test program to verify that basic gio async ops work correctly
in non-default contexts.

I'm not sure why we used the elaborate formula to convert the io-priority
to the priority of the mainloop idle when emulating async i/o with idles.
However, it causes the default io priority to be less than the normal
idle prio, so the i/o won't be scheduled if there is an idle outstanding.
There is really no great mapping to use here, doing blocking i/o in an
idle of any prio is generally bad and apps doing a lot of async i/o should
initialize threads. However, if we use the io-priority directly we at least
avoid the starvation problem above and make things easier to understand.
