and parse SUBPACKET status lines.
* ABI's to break:
+** Old opassuan interface.
** Implementation: Remove support for old style error codes in
conversion.c::_gpgme_map_gnupg_error.
** gpgme_edit_cb_t: Add "processed" return argument
about where to guarantee what (ie, what happens if start fails, are
the fds unregistered immediately - i think so?)
Note that we need support in gpgsm to set include-certs to default
- as RESET does not reset it.
+ as RESET does not reset it, also for no_encrypt_to and probably
+ other options.
** Optimize the case where a data object has an underlying fd we can pass
directly to the engine. This will be automatic with socket I/O and
descriptor passing.
