g10: Add TOFU support.

Browse source 
* configure.ac: Check for sqlite3.
(SQLITE3_CFLAGS): AC_SUBST it.
(SQLITE3_LIBS): Likewise.
* g10/Makefile.am (AM_CFLAGS): Add $(SQLITE3_CFLAGS).
(gpg2_SOURCES): Add tofu.h and tofu.c.
(gpg2_LDADD): Add $(SQLITE3_LIBS).
* g10/tofu.c: New file.
* g10/tofu.h: New file.
* g10/options.h (trust_model): Define TM_TOFU and TM_TOFU_PGP.
(tofu_db_format): Define.
* g10/packet.h (PKT_signature): Add fields digest and digest_len.
* g10/gpg.c: Include "tofu.h".
(cmd_and_opt_values): Declare aTOFUPolicy, oTOFUDefaultPolicy,
oTOFUDBFormat.
(opts): Add them.
(parse_trust_model): Recognize the tofu and tofu+pgp trust models.
(parse_tofu_policy): New function.
(parse_tofu_db_format): New function.
(main): Initialize opt.tofu_default_policy and opt.tofu_db_format.
Handle aTOFUPolicy, oTOFUDefaultPolicy and oTOFUDBFormat.
* g10/mainproc.c (do_check_sig): If the signature is good, copy the
hash to SIG->DIGEST and set SIG->DIGEST_LEN appropriately.
* g10/trustdb.h (get_validity): Add arguments sig and may_ask.  Update
callers.
(tdb_get_validity_core): Add arguments sig and may_ask.  Update
callers.
* g10/trust.c (get_validity) Add arguments sig and may_ask.  Pass them
to tdb_get_validity_core.
* g10/trustdb.c: Include "tofu.h".
(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
level.  Combine it with the computed PGP trust level, if appropriate.
* 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.
* g10/keylist.c: Include "tofu.h".
(public_key_list): Also show the PGP stats if the trust model is
TM_TOFU_PGP.
(list_keyblock_colon): If the trust mode is tofu or
tofu+pgp, then show the trust policy.
* g10/pkclist.c: Include "tofu.h".
* g10/gpgv.c (get_validity): Add arguments sig and may_ask.
(enum tofu_policy): Define.
(tofu_get_policy): New stub.
(tofu_policy_str): Likewise.
* g10/test-stubs.c (get_validity): Add arguments sig and may_ask.
(enum tofu_policy): Define.
(tofu_get_policy): New stub.
(tofu_policy_str): Likewise.
* doc/DETAILS: Describe the TOFU Policy field.
* doc/gpg.texi: Document --tofu-set-policy, --trust-model=tofu,
--trust-model=tofu+pgp, --tofu-default-policy and --tofu-db-format.
* tests/openpgp/Makefile.am (TESTS): Add tofu.test.
(TEST_FILES): Add tofu-keys.asc, tofu-keys-secret.asc,
tofu-2183839A-1.txt, tofu-BC15C85A-1.txt and tofu-EE37CF96-1.txt.
