* command.c: Make CMD_ERR_NOTHING_TODO nonfatal if reading
configuration from file. Fixes critical bugzilla #113.
* smux.c, smux.h: Remove all defaults to initialize smux connection to
snmpd by default even if not configured to do so. "smux peer OID
<password>" initializes now connection and "no smux peer" terminates
it.
