rules (interface was already there). since the nat.conf/pf.conf merge the
parser accepted these but didn't expand them. ugh.

1) Eliminate more if's in favour of 'cond || stmt' or
'cond && stmt' constructs.
2) Global _didnet -> DIDNET, make local _nam a local.
3) Display 'DHCP not supported' error every time user
specifies 'dhcp' but the client is not present.
4) if if_extra is empty, that's ok, so just assign
$resp to it whether $resp is empty or not.
5) Check for DIDNET inside donetconfig() instead of
before each call to donetconfig.
6) Eliminate superfluous 'Aborting' comments, and let
the user draw their own conclusion from getting the
'Extract more sets' message.
7) Minor code tweaks like not continually assigning
$resp to a value in a loop, when all we want is
the final value, and only displaying 'Skipping'
message in tape installs if we are actually
skipping files, etc.

does not work

1) Factor out inquiring for a device. ask_fordev()
now does this for root disk determination, other
disk initialization, install sets disk or cd
inquiry. Also ensures cd devices are created on
the fly like disk devices already were, and
shortens some verbiage.
2) Just ask for root disk if install is skipping
disk initialization, rather than doing the
'df /mnt ...' scan, since 1) we just end up asking
anyway and 2) everything *should* have been
umount'ed when previous install was finished or
interrupted.
3) getrootdisk -> get_rootdisk to conform to
get_<global> naming convention.
4) Add and use new global ROOTDEV rather than
constantly adding 'a' to ROOTDISK. ROOTDEV
default is set in get_rootdisk().
5) Put loop inside get_rootdisk rather than
always putting one around it. If no rootdisk
found/specified just exit install/update.
6) Eliminate getanotherdisk since ask_fordev()
does most of the work.
7) Eliminate parameter to check_fs, just use
ROOTDEV instead.
8) Some typographical and minor code tweaks.

"snapend - l" underflows; this fixes a buffer overflow with malformed
NFS packets, and may fix other buffer overflows with malformed packets.

pmap_t is the exception, it is required by the MI code so pmap_t will
be used instead of using 'struct pmap *' in the code. (consistency)

run destructors on dlclose()
Move more symbols into _dl_ private space, so that the proper (libc)
version of the function will be used.
Add readdir() functionality to perform the proper library searching.
Support DL_PRELOAD
Do not relocate symbols if ld.so is being traced (and will exit).
Misc lint cleanup.

only i810 driver was tested though.
based on the netbsd's lkm, initially ported
by hunter@dg.net.ua and later made into shape by mickey.

to get shared locks for lookup and get the exclusive lock only with
LK_DRAIN on unmount and do the real exclusive locking with flags in
mnt_flags, we now use shared locks for lookup and an exclusive lock for
unmount.
This is accomplished by slightly changing the semantics of vfs_busy.
Old vfs_busy behavior:
- with LK_NOWAIT set in flags, a shared lock was obtained if the
mountpoint wasn't being unmounted, otherwise we just returned an error.
- with no flags, a shared lock was obtained if the mountpoint was being
unmounted, otherwise we slept until the unmount was done and returned
an error.
LK_NOWAIT was used for sync(2) and some statistics code where it isn't really
critical that we get the correct results.
0 was used in fchdir and lookup where it's critical that we get the right
directory vnode for the filesystem root.
After this change vfs_busy keeps the same behavior for no flags and LK_NOWAIT.
But if some other flags are passed into it, they are passed directly
into lockmgr (actually LK_SLEEPFAIL is always added to those flags because
if we sleep for the lock, that means someone was holding the exclusive lock
and the exclusive lock is only held when the filesystem is being unmounted.
More changes:
dounmount must now be called with the exclusive lock held. (before this
the caller was supposed to hold the vfs_busy lock, but that wasn't always
true).
Zap some (now) unused mount flags.
And the highlight of this change:
Add some vfs_busy calls to match some vfs_unbusy calls, especially in
sys_mount. (lockmgr doesn't detect the case where we release a lock noone
holds (it will do that soon)).
If you've seen hangs on reboot with mfs this should solve it (I repeat this
for the fourth time now, but this time I spent two months fixing and
redesigning this and reading the code so this time I must have gotten
this right).

The flag can be either HOOK_REMOVE or HOOK_REMOVE|HOOK_FREE.
o HOOK_REMOVE removes the hook from the list before executing it.
o HOOK_FREE frees the hook after that.
- Let dostartuphooks use HOOK_REMOVE|HOOK_FREE so we can reclaim the memory.
- Let doshutdownhooks use HOOK_REMOVE so that when some shutdown hook
panics (they do that all the #@$%! time these days) we don't loop
for ever. Don't HOOK_FREE, it doesn't matter and I don't want to add
another possible panic condition for shutdown hooks.
- Actually free the pointer we're throwing away in hook_disestablish (I wonder
how much memory this has leaked over the years).
