commit d05ff81732e20e6f9d6d7a6281a96a312b001abb
Author: Neal H. Walfield <neal at g10code.com>
Date:   Wed Oct 21 13:28:15 2015 +0200

    gpg: Keep the trust DB up to date for the tofu and tofu+pgp models.
    
    * g10/trustdb.c (init_trustdb): Recognize tofu and tofu+pgp as
    possibly saved trust models.  Also register the ultimately trusted
    keys if the trust model is tofu or tofu+pgp.
    (check_trustdb): Don't skip if the trust model is tofu or tofu+pgp.
    (update_trustdb): Likewise.
    (tdb_check_trustdb_stale): Likewise.
    (validate_keys): If the trust model is TOFU, just write out the
    ultimately trusted keys.
