Libpri is lax in checking if a missing channel identification ie is mandatory for the SETUP ACKNOWLEDGE, PROCEEDING, ALERTING, and CONNECT messages. That ie is mandatory when those messages are the first response to a SETUP message sent by the CPE side.

Make coding errors in mandatory ie's send a STATUS with cause 100 "Invalid information element contents" in response. Also fix detection of coding errors in channel identification ie.
