Summary:                    [patch] lock in sip_tcp_helper_thread
Description: 
Asterisk locked out during normal sip call processing. It seems, that bug
is in sip/tcp handling (one peer used sip over tcp when this lock
happened).

---------------------------------------------------------------------- 
This should fix it.  I think the problem is that the SSL layer may need to
do renegotiation, and when that happens, SSL_read and SSL_write may return
errors indefinitely.  Therefore, the underlying implementation of the FILE
pointer needs to have visibility to the locking (and, in fact, control the
locking).
