all the SUBDIR entries in parallel, instead of serially. Apply this
option to a selected number of Makefiles, which can greatly speed up the
build on multi-core machines, when using make -j.
This can be extended to more Makefiles later on, whenever they are
verified to work correctly with parallel building.
I tested this on a 24-core machine, with make -j48 buildworld (N = 6):
before stddev after stddev
======= ====== ======= ======
real time 1741.1 16.5 959.8 2.7
user time 12468.7 16.4 14393.0 16.8
sys time 1825.0 54.8 2110.6 22.8
(user+sys)/real 8.2 17.1
E.g. the build was approximately 45% faster in real time. On machines
with less cores, or with lower -j settings, the speedup will not be as
impressive. But at least you can now almost max out a machine with
buildworld!

This change is a proof of concept on how to easily integrate existing
tests from the tools/regression/ hierarchy into the /usr/tests/ test
suite and on how to adapt them to the new layout for src.
To achieve these goals, this change:
- Moves tests from tools/regression/bin/<tool>/ to bin/<tool>/tests/.
- Renames the previous regress.sh files to legacy_test.sh.
- Adds Makefiles to build and install the tests and all their supporting
data files into /usr/tests/bin/.
- Plugs the legacy_test test programs into the test suite using the new
TAP backend for Kyua (appearing in 0.8) so that the code of the test
programs does not have to change.
- Registers the new directories in the BSD.test.dist mtree file.

Add directory names directly and sort at the end.
Include bsd.arch.inc.mk so we can, in the future, more easily make arch
dependent changes in /bin (unlikely, but is needed for symmetry).
This is similar to the Solaris utility of the same name.
Some use cases:
* rc.subr's wait_for_pids
* interactive use, e.g. to shut down the computer when some task is done
even if the task is already running

for the convenience of rc.d. Now it has happily lived there for quite
a while. So move the pkill(1) source files from usr.bin to bin, too.

- Unify the conditional assignments section so that architectural
exclusions come first, then options and !options, sorted by the
option name, also in directory order, then architecture specific
sections, sorted by the architecture name, with i386 being a
traditional exception.

true in /etc/make.conf. Both qmail and smail use a different rmail, so
replacing rmail is a Bad Thing.

All the rest work! Actually, I don't know if chio works because I can't
test that. df can be built using NetBSD's mount.h. ps depends on libkvm
so there is no point trying.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
