gpg,gpgsm: Record the creation time of a private key.
* sm/call-agent.c (gpgsm_agent_genkey): Pass --timestamp option. (gpgsm_agent_import_key): Ditto. * g10/call-agent.c (agent_genkey): Add arg timestamp and pass it on. (agent_import_key): Ditto. * g10/import.c (transfer_secret_keys): Pass the creation date to the agent. * g10/keygen.c (common_gen): Ditto.
Having the creation time in the private key file makes it a lot easier
to re-create an OpenPGP public keyblock in case it was accidentally
lost.
