Subject: [PATCH] sip_parser: Fix return code in pjsip_find_msg and add
"volatile"
The default return code for pjsip_find_msg was PJ_SUCCESS so if
a Content-Length header wasn't found at all, pjsip_find_msg was
returning PJ_SUCCESS instead of PJSIP_EMISSINGHDR.
Also added the volatile keyword to a few variables what are used
both insude and outsude the PJ_TRY/PJ_CATCH block.
