machine-independent code and try mounting the devices in the
lists instead of guessing alternative root devices in a machine-
dependent way.
autoconf.c:
Reject preposterous slice numbers instead of silently converting
them to COMPATIBILITY_SLICE.
Don't forget to force slice = COMPATIBILITY_SLICE in the floppy
device name.
Eliminated most magic numbers and magic device names in setroot().
Fixed dozens of style bugs.
vfs_conf.c:
Put the actual root device name instead of "root_device" in the
mount struct if the actual name is available. This is useful after
booting with -s. If it were set in all cases then it could be used
to do mount(8)'s ROOTSLICE_HUNT and fsck(8)'s hotroot guess better.
- don't announce `mtree' as `mtools'.
- don't install to ${DESTDIR}/usr/sbin (which often doesn't exist if
DESTDIR is set and may be read-only if DESTDIR is not set).
- install to (${WORLDTMP}/usr/sbin so that the new mtree is actually
in $PATH if DESTDIR is set.
- don't use the host make or the host sys.mk. This is probably
unimportant.
- use a temporary obj dir like the one for `make'. This was mainly
necessary because I forgot to remove the MAKEOBJDIRPREFIX unsetting
which was just a bug for mtree. A non-quick fix would handle mtree
more like a bootstrap tool (the only additional complications are to
create ${BINDIR} and avoid excessive cleaning). Except a non-quick
fix would change much more.

enough aliases to fill MAXHOSTNAMELEN * 2 characters in them.
Good candidate for merging back into -stable. Lightly tested by me, but
it came from OpenBSD a while ago.

use strncat correctly
check buffer size in graph_name
Change paths from /tmp to /var/run for server sockets
This has been building in my tree for ages, but has remained lightly
tested.

o Add more checks for buffer overflows
o Use snprintf rather than strcat/cpy and have better checks for max
length exceeded.
Most of these changes are not exploitable buffer overruns, but it never
hurts to be safe.

In particular, don't generate an include of "opt_compat.h" if it
wouldn't affect anything we create. This will fix recent breakage
of the ibcs2 LKM. The ibcs2 syscall files were not regenerated
properly, so the LKM didn't break immediately when we started
generating this extraneous include.

rename("D1/X/", "D2/Y/") gives a wrong link count for D2.
