Summary:                    [patch] Deadlock in chan_sip.c handle_incoming()
Description: 
There are several bug reports open which involve deadlocks in chan_sip.c
handle_incomig() not having a channel lock held before a pvt lock:
    https://issues.asterisk.org/view.php?id=19117
    https://issues.asterisk.org/view.php?id=19107
    https://issues.asterisk.org/view.php?id=19112

These deadlocks will apply to 1.6.2.18 and to 1.8.4, but I also believe
that branches/1.8  and trunk/ already contain a fix that comes from
https://reviewboard.asterisk.org/r/1182/ that removes this issue by
removing the 
request_queue from chan_sip.c completely.
