gpg: Use the new MANUFACTURER attribute.
* g10/call-agent.h (struct agent_card_info_s): Add manufacturer fields. * g10/call-agent.c (agent_release_card_info): Release them. (learn_status_cb): Parse MANUFACTURER attribute. * g10/card-util.c (get_manufacturer): Remove. (current_card_status): Use new attribute.
This does away with the duplicated OpenPGP vendor tables; they are now
at a better place (app-openpgp.c).
