Change PNF to use functions pointers to pack/unpack messages.

Browse Source 
Adds 3 new function pointers to the P5 and P7 PNF structures, allowing to configure which function to use to pack/unpack the messages, as well as unpack the message header, being then used seamlessly regardless of using the FAPI or nFAPI functions.

Changes the header unpack and message unpack functions to return true on success and false on failure, instead of an int
