Subject: - use C99 compiler flags - implement some getopt/setopt functions for
 UID and layer2 specific parameters - basic rfid scanning support - add
 commandline arguments for layer2 / scanning to librfid-tool - try to detect
 both supported readers automatically in librfid-tool - add new 'l2_supported'
 and 'proto_supported members to rfid_reader
