Add a new routine "default_print_packet()", which takes a pointer to the
beginning of the raw packet data, the captured length of the raw packet data, and the length of the link-layer header, and: if "-e" was specified, prints all the raw packet data; if "-e" was not specified, prints all the raw packet data past the link-layer header, if there is any. Use that routine in all the "xxx_if_print()" routines if "-x" was specified. Make "arcnet_encap_print()" static - it's not used outside "print-arcnet.c". Add missing info printing code to "atm_if_print()". Print the packet data in "lane_if_print()", not in "lane_print()", as "lane_print()" can be called from other "xxx_if_print()" routines, and those routines will also print the packet data if "-x" was specified - no need to print it twice.
