Add new F1AP msg enc&dec library
Add a new target f1ap_lib that groups F1AP ASN.1 encoding&decoding for messages defined f1ap_messages_types.h. The objective is to, for each F1AP message, - add encoder&decoder (similar to what already exists, but without mandatory message sending afterwards) - eq_X() function that checks two messages for equality (to be used mostly in tests) - cp_X() function that deep-copies a message, e.g., to be used when sending ITTI messages, instead of manual copying done currently - free_X() function that frees the memory associated to a memory, to avoid memory leaks. Each message will be tested, notably that encoding&decoding as well as copying yield identical messages. The actual message encoding & decoding, tests, and their use will be done in the forthcoming commits.
