-Subject: [PATCH] Create generic pjsip_hdr_find functions
-
-pjsip_msg_find_hdr(), pjsip_msg_find_hdr_by_name(), and
-pjsip_msg_find_hdr_by_names() require a pjsip_msg to be passed in
-so if you need to search a header list that's not in a pjsip_msg,
-you have to do it yourself. This commit adds generic versions of
-those 3 functions that take in the actual header list head instead
-of a pjsip_msg so if you need to search a list of headers in
-something like a pjsip_multipart_part, you can do so easily.
