[sccp] Invent new API to be used by the BSC NAT

I want to reuse the SCCP code for header parsing in the BSC
NAT to identify data and patch the source local reference. To do
this the current handle_* methods will be changed into two parts
one is strictly parsing the other is handling the parsed data.
