5f04ebd4d3 Fix an inverted conditional in the netrc code, which would ignore the
value of $HOME and always use the home directory from the passwd
database, unless $HOME was unset, in which case it would use (null).

While there, clean up handling of netrcfd and add debugging aids.

23d2383783 Bump the date on man pages in r334306
It seems a shame to ruin the patina of the June 4, 1993 date
on abort.3, especially since it still matched the date of
the SCCS ID, but those are the rules.

959826ca1b pmc(3)/hwpmc(4): update supported Intel processors to rely fully on the
vendor provided pmu-events tables and sundry cleanups.

The vendor pmu-events tables provide counter descriptions, default
sample rates, event, umask, and flag values for all the counter
configuration permutations. Using this gives us:

- much simpler kernel code for the MD component
- helpful long and short event descriptions
- simpler user code
- sample rates that won't overload the system

Update man page with newer sample types and remove unused sample type.

preserve existing behavior, add -DNO__SCCSID to CFLAGS to not

9891578a40 Plug a memory leak and potential NULL-pointer dereference introduced in r331214.
Each TCP connection that uses the system default cc_newreno(4) congestion
control algorithm module leaks a "struct newreno" (8 bytes of memory) at
connection initialisation time. The NULL-pointer dereference is only germane
when using the ABE feature, which is disabled by default.

While at it:

- Defer the allocation of memory until it is actually needed given that ABE is
  optional and disabled by default.

- Document the ENOMEM errno in getsockopt(2)/setsockopt(2).

- Document ENOMEM and ENOBUFS in tcp(4) as being synonymous given that they are
  used interchangeably throughout the code.

- Fix a few other nits also accidentally omitted from the original patch.
