Hah.  I guess nobody has tried to modify a notmuch database using the
Go bindings.

Could this instead assign the constants to
C.NOTMUCH_DATABASE_MODE_READ_ONLY, etc, rather than duplicating their
values?  It would be nice to do that for the Status values as well
(which are correctly using iota, at least).
