KAME/NetBSD 1.4, SNAP kit 19990705 (forgot to add)
bring in latest KAME (as of 19991130, KAME/NetBSD141) into kame branch
just for reference purposes.
This commit includes 1.4 -> 1.4.1 sync for kame branch.

The branch does not compile at all (due to the lack of ALTQ and some other
source code).  Please do not try to modify the branch, this is just for
referenre purposes.

synchronization to latest KAME will take place on HEAD branch soon.
(once again in the right place)

initial import of pigz 2.1.6 sources.

from http://www.zlib.net/pigz/:
"""
pigz, which stands for parallel implementation of gzip, is a fully functional replacement for gzip that exploits multiple processors and multiple cores to the
hilt when compressing data. pigz was written by Mark Adler, and uses the zlib and pthread libraries.

How is it pronounced?
I'm glad you asked. It is pronounced "pig-zee". It is not pronounced like the plural of pig.
"""

once i am done adding bz2 support to pigz, i plan to obsolete my usr.bin/gzip.
