Summary:                    [patch] Asterisk to GoogleTalk client communications
fail
Description: 
Hi, 

Calling from a SIP phone an extension that opens a Gtalk channel causes
either a deadlock issue or unexpected call teardown.

In the first case (guest account is used in the gtalk.conf configuration
file), some mutex is kept locked, and Asterisk dumps explicit error
messages like :
[Feb  2 16:51:55] ERROR[18298]:
/home/sultan/src/asterisk/trunk/include/asterisk/lock.h:244
__ast_pthread_mutex_lock: chan_gtalk.c line 1530 (gtalk_parser): Deadlock?
waited 155 sec for mutex '&((struct gtalk *) data)->_lock'?

The second problem is caused by Asterisk not responding to a Gtalk IQ
(Information Query) from the remote GoogleTalk client. This makes the
GoogleTalk client close the call after some time.

The attached patch corrects those issues, and possibly other observed
failures in bug http://bugs.digium.com/view.php?id=8193.
