	queue up a request to perform filtering.  For bug #4422.

	* providers/imap/camel-imap-store.c (camel_imap_msg_new): Create a
	new 'imap msg'.
	(camel_imap_msg_queue): Queue an 'imap msg'.
	(async_received): Handle receiving of imap msg in async thread.
	(async_destroy): Handle destroying of imap msg.
	(camel_imap_store_finalize): Destroy thread when done.
	(camel_imap_store_init): Setup thread.
