agent: Make --disable-extended-key-format a dummy option.
* agent/agent.h (opt): Remove enable_extended_key_format. * agent/gpg-agent.c (enum cmd_and_opt_values): Turn oDisableExtendedKeyFormat and oEnableExtendedKeyFormat into dummy options. * agent/protect.c (do_encryption): Remove arg use_ocb and corresponding code. (agent_protect): Ditto. Change all callers. * agent/findkey.c (agent_write_private_key): Simplify due to the removal of disable-extended-key-format. (write_extended_private_key): Fold into agent_write_private_key.
This change is related to
but should have no visible effect except for the removal of
option --disable-extended-key-format.
