Propagate isroot, throughout the eval process and maintain it properly.
Fixes sleep 10 | cat^C not exiting because sleep and cat ended up in
their own process groups, because wasroot was always true in the children.
-dynamic-linker=/libexec/ld.elf_so) if the BINDIR of the program being
built is /bin or /sbin.
The reason we do this is because now all programs *except* those in
/bin and /sbin (i.e. the "special cases") match the default the compiler
uses, which is what is used for things in e.g. xsrc, pkgsrc, and other
random 3rd party programs.
This is done by decoupling where a shlib is installed from how it
is located. Two new variables, SHLIBINSTALLDIR and SHLINKINSTALLDIR,
contain the former information, and key off MKDYNAMICROOT only. SHLIBDIR
and SHLINKDIR contain the latter, and key off MKDYNAMICROOT and BINDIR.
The SHLIBINSTALLDIR, SHLIBDIR, _LIBSODIR, SHLINKINSTALLDIR, and
SHLINKDIR parameters are moved to a new <bsd.shlib.mk>; see bsd.README
for usage details.
Plus my changes:
- walking process group fix in foregrounding a job.
- reset of process group in parent shell if interrupted before the wait.
- move INTON lower in the dowait so that the job structure is
consistent.
- error check all setpgid(), tcsetpgrp() calls.
- eliminate unneeded strpgid() call.
- check that we don't belong in the process group before we try to
set it.
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)).
race conditions -- now we always synchronously wait for the job to finish.
In evalcommand(), add the same INTOFF/INTON locking as evalpipe(), to prevent
leaving internal state inconsistent, and also to insure that we synchronously
wait for the job.

too. The code in display() could possibly be a bit smarter about this
requirement...
