the original channel callerid.
- added config 'defaultcid' to set a default caller id which will be
used if dial option 'd' is specified.
- moved ast_softhangup() out of interface lock
- use correct mutex_init call for interface lock
- when 'o' option is used for overlap dialing, do not send any digits
with the CONNECT_REQ. This gives better progress together with 'b'.
