Review request for Asterisk Developers and Mark Michelson.


Summary
-------

Previously, Asterisk only processed session timer information if both
the 'Supported: timer' and 'Session-Expires' headers were
present. However, the Session-Expires header is optional. If we were
to receive a request with a Min-SE greater than our configured
session-expires, we would respond with a 'Session-Expires' header that
was too small.

This patch cleans the situation up a bit, always processing timer
information if the 'Supported: timer' header is present.


This addresses bug ASTERISK-20787.
