i.e. this makes emacs usable from system(3). Programs called from
shellscripts are now required to exit with proper signal status. That
means, they have to kill themself. Exiting with faked numerical exit
code is not sufficient.
Exit with proper signal status if script exits on signal.
Make the wait builtin interruptable, both with and without traps set.
Use volatile sig_atomic_t where (and only where) appropriate.
(Almost) fix printing of newlines on SIGINT.
Make traps setable from trap handlers. This is needed for shellscripts
that catch SIGINT for cleanup work but intend to exit on it, hance
have to kill themself from a trap handler. I.e. mkdep.
While I'm at it, make it -Wall clean. -Wall is not enabled in
Makefile, since vararg warnx() macro calls in usr.bin/printf/printf.c
are not -Wall-able.

effectively overriding the dynamically-sized-column feature. This
is mostly useful for non-interactive use, where it may be necessary
to ensure that listings taken at different times have columns that
line-up correctly. I have been assured that at least one large,
well-known program will soon be taking advantage of this. :-)

Removed explicit dependencies of foo.o on foo.c. These were mainly
placeholders for comments about missing dependencies of tools objects
on headers. This problem needs to be handled more generally.

Use /dev/null for opening the kvm library, we don't need access to /dev/mem
anymore.
ps can now run without the setgid(kmem) bit. If it does it will not be
able to show argv/envp for another uid's processes unless you are root.

This should calm down attempts to `cp -p' to a nfs mount or some other
filesystem that doesn't accept flags or all combinations of flags.
It will warn if it fails to change flags though.

Clean up (or if antipodic: down) some of the msgbuf stuff.
Use an inline function rather than a macro for timecounter delta.
Maintain process "on-cpu" time as 64 bits of microseconds to avoid
needless second rollover overhead.
Avoid calling microuptime the second time in mi_switch() if we do
not pass through _idle in cpu_switch()
This should reduce our context-switch overhead a bit, in particular
on pre-P5 and SMP systems.
WARNING: Programs which muck about with struct proc in userland
will have to be fixed.
