[PATCH 0/14] Implement and use database "features"

This series is not as long as it looks!  Patch 5 is the only one
that's even slightly lengthy and almost any prefix of the series can
be sensibly reviewed and pushed on its own.

This series implements support for database features as described in
my earlier proposal [1].  This should simplify future database schema
changes and upgrades, enabling us to iterate faster on notmuch's core.
It also substantially improves forward and backwards compatibility and
improves user error reporting related to compatibility.  Patches 9 and
on make use of database features throughout the rest of libnotmuch to
simplify and improve code, improve performance, and even make the
libnotmuch interface safer and easier to use correctly.

Once features support has been merged, it should be easy to implement
various pending changes, including ghost messages [2] (I have this
mostly implemented already) and ctimes [3].
