Implement MKDYNAMICROOT, which currently defaults to "no", but will
be changed in the future to "yes".

If MKDYNAMICROOT == "no", there is no change from existing behaviour
of a static /bin and /sbin (and a few programs in elsewhere).

If MKDYNAMICROOT == "yes", the following changes occur:
in <bsd.own.mk>:
SHLIBDIR?= /lib
SHLINKDIR?= /lib
in various Makefiles, the following entry is DISABLED.
LDSTATIC?=-static
This results in all programs (except those "standalone" programs built
in sys/arch/*/stand) are linked dynamically, the shared linker is moved
from /usr/libexec to /lib (with a compat symlink), and the shared
libraries used by /bin and /sbin programs are moved from /usr/lib to
/lib (with compat symlinks).

back out previous change - this needs to be discussed first at least

don't link these static; if shared libraries are hosed, these utilities would
surely not save the situation, not help to recover from it

- remove duplicated setting for LDSTATIC in ktruss/Makefile.
- fix command name in SYNOPSIS section of man page.
- link ktrace man page to ktruss man page.
- add executable and man page for ktruss in distrib sets.

allow LDSTATIC definition to be overridden by bsd.own.mk/mk.conf

the traced process. Add a flag to override (-n) this behavior and have the
trace stop without blocking the traced process (the previous behavior).

[ktruss] Use fork(2), not vfork(2).
The child process of do_ktrace() does return and the stack is
changed by another function call (execvp()).
By using vfork() (my previous change), the execution of the parent
process resumes on the modified stack. Oops.
We could use vfork() carefully, but for now use fork().

Problem reported and investigated by Ethan Solomita <ethan@geocast.com>.
Thanks.

DTRT vs setemul() (for ktruss, similar to kdump.c)

update to setemul() changes

Make ktrace(1) not affect interactions between processes.
Following examples show the cases.

% ktrace -f - false >/dev/null && echo wrong
wrong
% ktrace -f - -i /usr/sbin/update >/dev/null
(does not return to command line)

That is, back out last change and restore the roles of parent/child for
ktrace(1). The ktruss(1) stuff still remains.
Yes, ktruss(1) has the problems. Better implementation is expected.

branches: 1.12.2;
Change behaviour from running the command as the parent and ktrace/ktruss as
the child to be ktruss/ktrace is the parent. This fixes a problem with ktruss
where the prompt would be returned in the middle of output.

Fix fowllowing problems:

1. If fork()ing, the program is executed twice.
2. If the ktruss(1) output is bufferd, the final output is not flushed
(because it is executing).
