Summary:                    [patch] Crash in chan_sip -- sip_setoption()
Description: 
If the sip private structure is null, sip_setoption() will defref the null
pointer and crash.

I don't know what the exact fix would be, but a stopgap would prevent a
crash here.

Possibly all the operations on sip private structures should check their
pointer first?

I think this may be a duplicate of
https://issues.asterisk.org/view.php?id=18732.  Can you confirm if it is?  If
so, then a bug marshal can add a relation to that issue.
