c10a556f9b Change basename(3) and dirname(3) to return a pointer to static 
storage, rather than modifying their input arguments.  While not
reentrant, this is explcitly allowed by IEEE Std 1003.1-2001 (which
allows either behavior, stating that it is implementation-dependent).

The new semantics are considered less hostile/more useful by most programs
which use basename(3) and/or dirname(3) (several programs in the NetBSD
tree reimplement basename()/dirname() themselves to avoid modification
of the input argument).

This new implementation truncates results to PATH_MAX.  The Std does
not address this in the static storage case.  However since PATH_MAX
is the maximum pathname length in the Std, this should not be a problem
in practice.  Nontheless, it is noted in the BUGS section.

See the basename(3)/dirname(3) regression tests in src/regress/lib/libc.

Inspired by discussion with Niels Provos, related to PR 18647.

f28ce54243 if WITH_KQUEUE is defined and <sys/event.h> exists in DESTDIR, compile 
support for kqueue(2) and kevent(2) in

  will be made unconditional once kqueue branch would be merged

20d06f6b17 SI prefixes apply to decimal multiplies only. For binary (2^n) multiplies 
the most "officially looking" is IEC 60027-2, ie "Ki", "Mi", ...,
which is not too popular, and which would require more code changes.
So stick with the traditional capital "K" for (divisor==1024), and use
the SI "k" otherwise (ie (divisor==1000)).

If two signals are sent after each other without the process being run in
