gpgsm: Print revocation date and reason in cert listings.
* dirmngr/ocsp.c (ocsp_isvalid): Add args r_revoked_at and r_revocation_reason. * dirmngr/server.c (cmd_isvalid): Emit a new REVOCATIONINFO status. (cmd_checkocsp): Ditto. * sm/call-dirmngr.c (struct isvalid_status_parm_s): Add new fields. (isvalid_status_cb): Parse REVOCATIONINFO. (gpgsm_dirmngr_isvalid): Add args r_revoked_at and r_revocation_reason. * sm/gpgsm.h (struct server_control_s): Add fields revoked_art and revocation_reason. * sm/keylist.c (list_cert_raw): Print revocation date. (list_cert_std): Ditto.
Note that for now we do this only for OCSP because it is an important
piece of information when using the chain model. For a sample key see
commit 7fa1d3cc821dca1ea8e1c80a0bdd527177c185ee.
