dead kernel debugging. The previous code was a "do nothing".
The most obvious side effect of this is that you can now do things like
this and reasonably expect them to work:
dmesg -M /var/crash/vmcore.3 -N /var/crash/kernel.3
ps -axl -M /var/crash/vmcore.3 -N /var/crash/kernel.3
A good deal of this was lifted from the gdb code to do this, as well as
from NetBSD's libkvm (which has completely different VM macros)
and forwards compatable with version 3. This is needed to enable storing
a run-time library path in the dynamic linking headers. The crt startup
tries version 4 first, and falls back to version 3, so an executable that
is linked on -current will work with the ld.so on 2.1.x and less.

- removed references to nonexistent pathconf-related variables.
- document everything in CTL_MACHDEP(more than in sysctl.8) and
80% of the things in CTL_KERN (same as in sysctl.8).
- old static non-profiled libraries were removed in the wrong directory
if ${ORIG_SHLIBDIR} != ${LIBDIR}.
- old profiled libraries weren't removed.
- new shared compat libraries were installed in the wrong directory if
${ORIG_SHLIBDIR} != /usr/lib.
- some lines were too long.
Added some comments about cases that have caused problems. Changed
libfoo to ${LIB} so that libresolv/Makefile and libgnumalloc/Makefile
are almost identical.
complaints and suggestions about this over the last few days that I
cannot remember who has said what anymore. :-(
There is also a comment here about the intent of the process and another
explicit pointer to the etc/etc/rc change to that has been ignored by
quite a few people it seems.
stuff and detection for the "gnumalloc" port which doesn't exist and
nobody has cared enough about for the past 6 months or so to implement.
As has been pointed out to me (quite a few times) in email, the people
that had been bitten by the changes had failed to follow the instructions
about updating /etc/rc.
Bruce also pointed out that after my last commit, it was no longer
removing /usr/lib/libgnumalloc.so.2.0 as it should have been.
Hopefully this (and the comments in the Makefile) should defuse the problem
a bit.
Various neat features added. More documentation in the manpage.
If your machine has very little RAM, I guess that would be < 16M
these days :-(, you may want to try this:
ln -fs 'H<' /etc/malloc.conf
check the manpage.
Major version bumped (by me) since the ftpGet() public interface has
changed (an "int *" becomes and "off_t *")

as done after a quasi-recursive call to free() had modified what we
thought we knew about the last chunk of pages.
This bug manifested itself when I did a "make obj" from src/usr.sbin/lpr,
then make would coredump in the lpd directory.
