This is the high level entry for syncing messages in one direction.

Update statusfolder. Pass2: Remove locally deleted messages Get all UIDS in statusfolder but not self. These are messages that were deleted in 'self'. Delete those from dstfolder and statusfolder. After this pass, the message lists should be identical wrt the uids present (except for potential negative uids that couldn't be placed anywhere). Pass3: Synchronize flag changes Compare flag mismatches in self with those in statusfolder. If msg has a valid UID and exists on dstfolder (has not e.g. been deleted there), sync the flag change to both dstfolder and statusfolder.
