Implementation of PNF using WLS as message transport

Browse Source 
The common library exposes functions for the PNF to return the received blocks to the VNF for it to call WLS_Enqueue on them.
This is done in order to ensure the Blocks are returned after processing, also preventing the Dequeueing of blocks that are still being used, i.e. the internal value is not -1
All saved blocks are to be enqueued at the reception of a SLOT.indication by the VNF

Additionally, the definition of NFAPI_MAX_PACKED_MESSAGE_SIZE was moved to nfapi_interface.h and removed from the other headers, this is done to allow to set the maximum message size when using WLS by only changing the value in one place

Fixup fapi_nr_message_header_unpack call in nfapi_hex_parser
