Support the IMAP UIDPLUS extension (RFC 2359), which lets you

	resync after disconnected operation more efficiently, but also
	makes it possible to do appends and moves/copies more efficiently
	now.

	* providers/imap/camel-imap-folder.c (imap_append_message): If the
	server supports UIDPLUS, grab the APPENDUID response and cache the
	message into the folder's message cache.
	(imap_copy_messages_to): Likewise, for COPYUID, copy any message
	parts we have cached between the source and destination folder
	caches.
	(imap_get_message): If the entire message is already in the cache,
	just return that rather than building it from parts.
	(imap_update_summary): Fetch just the "UID FLAGS RFC822.SIZE" of
	the new messages first, then only fetch the headers for messages
	where we don't already have the headers cached.

	* providers/imap/camel-imap-message-cache.c: Add gtk-doc comments.
	(cache_put): Fix refcounting stuff here.
	(camel_imap_message_cache_insert_stream,
	camel_imap_message_cache_insert_wrapper): New.
	(camel_imap_message_cache_get): Fix a bug here so the memory
	caching actually works.
	(camel_imap_message_cache_copy): New routine, used by
	imap_copy_messages_to.

	* providers/imap/camel-imap-utils.c (imap_uid_set_to_array):
	Inverse operation of imap_uid_array_to_set. Used to parse COPYUID
	response.
