new: Enhance progress reporting
notmuch new reports progress only during the "first" phase when the files on disk are traversed and indexed. After this phase, other operations like rename detection and maildir flags synchronization are performed, but the user is not informed about them. Since these operations can take significant time, we want to inform the user about them. This patch enhances the progress reporting facility that was already present. The timer that triggers reporting is not stopped after the first phase but continues to run until all operations are finished. The rename detection and maildir flag synchronization are enhanced to report their progress.
