pjsip_messaging, pjsip_header_funcs: Crashes due to NULL pointer dereferences
Both res_pjsip_messaging and res_pjsip_header_funcs were causing asterisk to
crash because they were trying to dereference a NULL pointer.
In the case of res_pjsip_messaging it was attempting to "print" a contact
header that did not exist. In fact contact headers should not be part of
a SIP MESSAGE, so the offending code was simply removed.
In the case of res_pjsip_header_funcs a null private channel tech was being
passed to the function and then later dereferenced. Added null checks (and
error logging) to the read/write function handlers to guard against crashing.
(closes issue ASTERISK-22821)
