thread: Support queuing callbacks on any thread
Callbacks could be queued to be invoked either on the impl side or the main thread side of the thread; change this to take a GMainContext, which effectively means a callback can be queued to be invoked on any thread that has a GMainLoop running on its own GMainContext. Flushing is made to handle flushing callbacks synchronously on all threads. This works by keeping a hash table of queued callbacks per thread (GMainContext); when flushing (from the main thread), callbacks on the main thread context is flushed, followed by synchronization with all the other threads. meta_thread_flush_callbacks() is changed to no longer return the number of dispatched callbacks; it becomes much harder when there are N queues spread across multiple threads. Since it wasn't used for anything, just drop the counting, making life slightly easier. Feedback to thread tasks are however always queued on the callers thread.
