[PATCH 0/4 v4] lib: Maildir flags synchronization fixes

[Louis Rilling]

Hello,

Here is the updated series of fixes I have around maildir flags
synchronization. The first two patches are just cleanups that can be applied
independently.

The intent for the fourth patch (detailed in the commit log) is to allow mutt
users to keep using the "new" status, as long as notmuch can respect the
maildir specification.

The third patch implements a test for the new desired behavior. From recent
discussions I decided to put it before the actual changes, but it certainly can
move after if this is preferred.

Changelog:
* v4: 
 - rebased on top of release 0.8
 - included the test contributed by Michal Sojka
* v3: Added patch to kill the last usage of C++ type bool
* v2: Fix bool type as well as NULL returned despite having no errors (Austin
      Clements)

Thanks,

Louis
