gpg: Do not require a trustdb for decryption.

* g10/trustdb.c (init_trustdb): Add and implement arg NO_CREATE.
Change to return an error code.  Change all callers to to pass False
for NO_CREATE.
(tdb_get_ownertrust): New arg NO_CREATE.  Call init_trustdb to test
for a non-existing trustdb.  Change all callers to to pass False for
NO_CREATE.
(tdb_get_min_ownertrust): Ditto.
* g10/trust.c (get_ownertrust_with_min): Add arg NO_CREATE.  Call
init_trustdb for a quick check.
(get_ownertrust_info): Add arg NO_CREATE.
(get_ownertrust_string): Ditto.
* g10/gpgv.c (get_ownertrust_info): Adjust stub.
* g10/test-stubs.c (get_ownertrust_info): Ditto.
* g10/mainproc.c (list_node): Call get_ownertrust_info with NO_CREATE
set.
* g10/pubkey-enc.c (get_it): Ditto.
