Summary:                    IAX2 username is case-insensitive in registration,
but case sensitive in dialing
Description: 
If you have a username like 'tesT' in iax.conf, you will be able to
register it with 'Test', 'test', 'TEST', etc., but on the first call you'll
get:

[Jul 16 18:12:42] NOTICE[7465]: chan_iax2.c:7367 socket_process: Rejected
connect attempt from 10.0.2.231, who was trying to reach '102@'

In 'iax set debug' the username sent is plainly visible to be the right
one (when doing the registration and call attempt):

Rx-Frame Retry[ No] -- OSeqno: 001 ISeqno: 001 Type: IAX     Subclass:
REGREQ
   Timestamp: 00005ms  SCall: 00009  DCall: 00008 [10.0.2.231:4569]
   USERNAME        : Test
   MD5 RESULT      : a38988ba83a9c28590f555b7c32ebf29

The iax.conf entry is this:

[tesT]
type=friend
secret=test
callerid="test"
disallow=all
allow=gsm
context=sipin
auth=md5
qualify=no
host=dynamic
transfer=no

Fix a bug in iax2 registration that allowed peers to register with 
case-insensitive names (user_cmp_cb and peer_cmp_cb are now both 
case-sensitive).
