Subject: [PATCH GnuPG] gpg: Merge --rfc4880bis features into --gnupg

* g10/gpg.c (oRFC4880bis): Remove.
(opts): Make --rfc4880bis a Noop.
(compliance_options): Make rfc4880bis to gnupg.
(set_compliance_option): Remove rfc4880bis stuff.
(main): Ditto.  Note that this now activates the --mimemode option.
* g10/keygen.c (keygen_set_std_prefs): Remove rfc4880bis protection.
(keygen_upd_std_prefs): Always announce support for v5 keys.
(read_parameter_file): Activate the v4 and v5 keywords.
