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.

* since it's never possible to cancel a synchronous request in a
* single-threaded program, the request is done in the calling
* thread.
*
* 2. Asynchronous: An appropriate _g_asyncns_query_t is created, and
* then a GUnixResolverRequest is created with that query and a
* GSimpleAsyncResult. Two sub-possibilities:
*
* a. The resolution completes: g_unix_resolver_watch() sees that
* the request has completed, and calls
* g_unix_resolver_request_complete(), which detaches the
* "cancelled" signal handler (if it was present), queues the
* async_result to be completed, and then unrefs it.
*
* b. The resolution is cancelled: request_cancelled() calls
* _g_asyncns_cancel() to cancel the resolution. Then it calls
* g_unix_resolver_request_complete(), which detaches the
* signal handler, and queues async_result to complete in an
* idle handler. Because the asyncns resolution was cancelled,
* g_unix_resolver_watch() will never be triggered for this
* req.
*
* Since there's only a single thread, it's not possible for the
* request to both complete and be cancelled "at the same time",
* and each of the two possibilities takes steps to block the other
* from being able to happen later, so it's always safe to free req
* after the async_result completes.

*
* The various request possibilities:
*
* 1. Synchronous: handed off to the base class (GThreadedResolver);
* since it's never possible to cancel a synchronous request in a
* single-threaded program, the request is done in the calling
* thread.
*
* 2. Asynchronous: A GWin32ResolverRequest is created with
* appropriate query-specific information, a Windows event handle,
* and a GSimpleAsyncResult. This is then handed to the
* Windows-internal thread pool, which does the raw DNS query part
* of the operation (being careful to not call any glib methods
* that might fail when called from another thread when
* g_thread_init() has not been called). The main thread sets up a
* GSource to asynchronously poll the event handle. There are two
* sub-possibilities:
*
* a. The resolution completes: the threadpool function calls
* SetEvent() on the event handle and then returns.
*
* b. The resolution is cancelled: request_cancelled()
* disconnects the "cancelled" signal handler, and queues an
* idle handler to complete the async_result.
*
* Since we can't free the request from the threadpool thread
* (because of glib locking issues), we *always* have to have it
* call SetEvent and trigger the callback to indicate that it is
* done. But this means that it's possible for the request to be
* cancelled (queuing an idle handler to return that result) and
* then have the resolution thread complete before the idle handler
* runs. So the event callback and the idle handler need to both
* watch out for this, making sure we don't complete the same
* result twice.
