gpg: New export and import options "backup" and "restore".

* g10/export.c (parse_export_options): Add "backup" and its alias
"export-backup".
(do_export_one_keyblock): Export ring trust packets in backup mode.
* g10/import.c (parse_import_options): Add "restore" and its alias
"import-restore".
(read_block): Import ring trust packets.

These options are intended to, well, backup and restore keys between
GnuPG implementations.  These options may eventually be enhanced to
backup and restore all public key related information.
