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. svn path=/trunk/; revision=9635
