add options PIPE_SOCKETPAIR to individual kernel configs
the option is commented out on everything but kernels I was able
to recognize as INSTALL-like or ones for small memory machines
Standardise TCP_COMPAT_42 as commented out, grouped with other COMPAT options,
and with the comment '4.2BSD TCP/IP bug compat. Not recommended'
Add commented out 'TCP_DEBUG # Record last TCP_NDEBUG packets with SO_DEBUG'
(All hail amiga and atari which make some attempt to automate the
multiplicity of config files...)
