Werner Koch 202ed9e281
gpg: Support key flags for RENC, TIME, and GROUP. 
* g10/packet.h (PUBKEY_USAGE_RENC): New.
(PUBKEY_USAGE_TIME): New.
(PUBKEY_USAGE_GROUP): New.
* g10/getkey.c (parse_key_usage): Set the new key flags.
* g10/keyedit.c (show_key_with_all_names_colon): Show the new key
flags.
* g10/keyid.c (usagestr_from_pk): Ditto
* g10/keylist.c (print_capabilities): Ditto.
* g10/keygen.c (parse_usagestr): Parse line and set new flags.
(quickgen_set_para): Show flags.
--

See draft-koch-openpgp-2015-rfc4880bis-00 for the current version.
Actually these flags have been in the draft for years now.  This patch
is a first step to make use of them.
