Summary:                    [patch] deny=all in iax.conf results in segmentation
fault
Description: 
Specifying deny=all rather than disallow=all in the codec directive on an
IAX peer results in a seg fault. Changing deny=all to disallow=all results
in expected behavior.

Example improper use of the codec directive that causes a crash:
[bobloblaw]
deny=all
allow=ulaw
type=friend
host=172.20.20.5
qualify=yes
context=from-internal

Example of proper use of the codec directive that does not cause a crash:
[bobloblaw]
disallow=all
allow=ulaw
type=friend
host=172.20.20.5
qualify=yes
context=from-internal

---------------------------------------------------------------------- 
Note that this crash also occurs on seemingly valid constructs like:

deny=0.0.0.0/0.0.0.0
permit=0.0.0.0/0.0.0.0

Which some versions of FreePBX add to IAX peers by default. This bit me
after my recent upgrade to Asterisk 1.8.2.2.

Installing the suggested patch works fine.

This fix should get implemented ASAP!
