Now that each AioContext has a ThreadPool and the main loop AioContext can be fetched with bdrv_get_aio_context(), we can eliminate the concept of a global thread pool from thread-pool.c. The submit functions must take a ThreadPool* argument. block/raw-posix.c and block/raw-win32.c use aio_get_thread_pool(bdrv_get_aio_context(bs)) to fetch the main loop's ThreadPool. tests/test-thread-pool.c must be updated to reflect the new thread_pool_submit() function prototypes.
