aio: add a ThreadPool instance to AioContext
This patch adds a ThreadPool to AioContext. It's possible that some AioContext instances will never use the ThreadPool, so defer creation until aio_get_thread_pool(). The reason why AioContext should have the ThreadPool is because the ThreadPool is bound to a AioContext instance where the work item's callback function is invoked. It doesn't make sense to keep the ThreadPool pointer anywhere other than AioContext. For example, block/raw-posix.c can get its AioContext's ThreadPool and submit work. Special note about headers: I used struct ThreadPool in aio.h because there is a circular dependency if aio.h includes thread-pool.h.
