* providers/imap/camel-imap-folder.c: Add a "need_rescan" flag saying if we want to rescan the entire folder for flag changes next time it's selected. (camel_imap_folder_init): Set need_rescan TRUE. (camel_imap_folder_selected): If need_rescan is TRUE, call imap_rescan. (imap_refresh_info): Only do a full rescan if need_rescan is TRUE. Otherwise just do a NOOP, making this a MUCH more lightweight operation. Also, don't call imap_rescan directly if the folder isn't selected, since that could end up causing the folder to be scanned *twice* (imap_rescan -> camel_imap_command -> camel_imap_folder_selected -> imap_rescan). (imap_rescan): Set need_rescan FALSE. (imap_sync_online): Don't NOOP if no changes were pushed: the caller will call refresh_info if it wants to poll for changes. Fixes evolution-mail doing lots of unnecessary extra work at quit time. svn path=/trunk/; revision=10010
