tcp_debug.h defaults to a 100 element tcp_debug array, which can
	be used in conjunction with TCPDEBUG to enable logging of various
	tcp events. Without TCPDEBUG it just provides a small history of
	packets with SO_DEBUG, which can be manually examined.

	For low memory machines, particularly on install kernels, this is
	extra memory usage we do not need.

	Would anyone object if I made tcp_trace conditional on a
	kernel TCP_TRACE option, defaulted to on in all GENERICs.
	(TCP_TRACE rather than TCPTRACE to match up with TCP_SIGNATURE
	and TCP_COMPAT_42, as well as being easier to read).
