(trust_model_string): Handle TM_TOFU and TM_TOFU_PGP.
(tdb_get_validity_core): Add arguments sig and may_ask.  If
OPT.TRUST_MODEL is TM_TOFU or TM_TOFU_PGP, compute the TOFU trust

* g10/keyedit.c: Include "tofu.h".
(show_key_with_all_names_colon): If the trust mode is tofu or
tofu+pgp, then show the trust policy.
