gpg: Change keydb_search to not return legacy keys.

* g10/keyring.c (keyring_search): Take new argument, ignore_legacy.
If set, skip any legacy keys.  Update callers.
* g10/keydb.c (keydb_search): Skip any legacy keys.
(keydb_search_first): Don't skip legacy keys.  Treat them
as an error.
(keydb_search_next): Likewise.
(keydb_search_fpr): Likewise.
* g10/export.c (do_export_stream): Likewise.
* g10/getkey.c (lookup): Likewise.
(have_secret_key_with_kid): Likewise.
* g10/keylist.c (list_all): Likewise.
(keyring_rebuild_cache): Likewise.
* g10/keyserver.c (keyidlist): Likewise.
* g10/trustdb.c (validate_key_list): Likewise.
