Use socketcan.[c|h] for shared (Socket)CAN functionality where the wiretaps create records of the WTAP_ENCAP_SOCKETCAN encapsulation type. Adjust existing "homegrown" structures to use as much of the "shared" data structures from socketcan.h so that all can use the single function wtap_socketcan_gen_packet() to create records.
