notmuch new: Proper support for renamed and deleted files.

Browse source 
The "notmuch new" command will now efficiently notice if any files or
directories have been removed from the mail store and will
appropriately update its database.

Any given mail message (as determined by the message ID) may have
multiple corresponding filenames, and notmuch will return one of
them. When a filen is deleted, the corresponding filename will be
removed from the message in the database. When the last filename is
removed from a message, that message will be entirely removed from the
database.

All file additions are handled before any file removals so that rename
is supported properly.
