The arguments for RX n-tuple traffic direction are filled into
structure fields of varying size, some of which are in big-endian
rather than native byte order. Currently parse_generic_cmdline()
only supports 32-bit integers in native byte order, so this does
not work correctly.
Replace CMDL_INT and CMDL_UINT with the more explicit CMDL_S32 and
CMDL_U32. Add CMDL_U16 and CMDL_U64 for narrower and wider integers,
and CMDL_BE16 and CMDL_BE32 for big-endian unsigned integers. Use
them for RX n-tuple argument parsing.

I've removed the 'historical' comment from the kernel-style named types
because I see no sign of a transition away from them.
Ben.

Allow message type flags to be turned on and off by name.
Print the names of the currently set flags below the numeric value.
