tagged queuing support.
Ensure that we report that a device supports tagged queuing even if
the system is waiting a "command count delay" before starting to use
them.
If a user disables disconnects on a device ensure that tagged queuing
is also turned off. We did the right thing during initial configuration,
but could be confused by manual changes.
JAZ drive happy. This shouldn't impact fast drives, and will keep cam
from failing on very slow ones (that are spinning up, say). 20
seconds was almost long enough, but not in all cases.

well) Among them:
[ cd driver ]
1. Old labeling code was still there.
2. Error handling for dsopen() was broken (no test for the `error'
returned by dsopen(); bogus test of an `error' that is known to be 0).
3. cdopen() closed the physical device after certain errors although there
may still be open partitions on it.
4. cdclose() closed the physical device although there may still be open
partitions on it.
5. Some printf format fixes was incomplete or missing.
6. cdioctl() truncated unit numbers mod 256.
7. cdioctl() was missing locking.
[ da driver ]
1. daclose() closed the physical device although there may still be open
partitions on it. This was fixed many years ago in sd.c rev.1.57.
2. A minor optimization (the dk_slices != NULL test) in sdopen() became
uglier in daopen(). It is not worth doing. da only regressed compared
with od and my version of sd, since I never committed the change to sd.
daopen() should probably do less if some partition is already open.
This is not addressed by the diffs.

5. "opt_hw_wdog.h" was not included, so the HW_WDOG code was unreachable.
- Added a getdev CCB call in the cdopen() and daopen() calls so that the
vendor name and device name are available for the disklabel. (suggested
by bde)
- Removed vestigal devfs support in both drivers, since we can't properly
work with devfs yet. (ask bde for details on this)
- Cleaned up the probe code in both drivers in the failure cases. There
were a number of things wrong here. The peripheral driver instances
weren't getting properly cleaned up. Sometimes the wrong probe message
would get printed out (with the failure message appended), so it wasn't
very clear that we failed to attach. SCSI sense information was printed,
even when the error in question wasn't a SCSI error. I put similar fixes
into the changer driver in revision 1.2 of scsi_ch.c.

- Don't whine about nodes we can't stat(); these are usually
symlinks that lead out of the filesystem.
- Autoboot is now controlled by $autoboot_delay, which is a value
in seconds or NO to disable autoboot.
- Don't autoboot at the end of boot.conf if we have already tried.
- Add a 'read' command to complement 'echo'. Both are still hidden.
- Improve the 'source' command/function so that it is possible to
source scripts off removable media. The entire script is read and
saved before beginning execution. Script lines beginning with
'@' will not be echoed when being executed. Script execution will
normally terminate at the first error, however if the script line
begins with '-' this behaviour is overriden for that command.

The scandir() function returns -1 if it fails.
In many cases when this happens, it does not free
the memory that it allocated, resulting in a memory
leak, or close the directory opened with opendir().

(2) Add new variable WRKDIRPREFIX (defaults to ""). The "work"
directories are now in ${WRKDIRPREFIX}${.CURDIR}/work by default.
You can have a read-only ports tree (modulo any broken ports that
write something to places other than ${WRKDIR}) by setting this to
a writable location.
Ports that set WRKDIR explicitly should append this to front so
they will work when the user has WRKDIRPREFIX set.

FreeBSD repository version of this file and the isdn4bsd version,
adopt those changes from the i4b version that make this file
BSD-version independent. I attempted to avoid uglifying this file too
much, thus deviated a little from the i4b version (and hope they will
adopt the changes, too).
The diffs mostly concentrate on:
. #include differences between the systems
. different callout handling between FreeBSD vs. Net/OpenBSD
. interface naming (Net/OpenBSD store the ASCII name including the
unit # in struct ifnet, FreeBSD only the name)
. use of random() in FreeBSD vs. time-based pseudo-randomization in
Net/OpenBSD (for loopback detection ad CHAP challenges -- i
assume at least OpenBSD could also benefit from random(), but that's
the way i've got this file)
. interface address list elements are named a little differently
between FreeBSD and Net/OpenBSD
I attempted to segregate those compat fixes from other code fixes and
enhancements.

NFS_ROOT will produce kernel that cannot mount a UFS /.
Vfs type numbers must be distinct from VFS_GENERIC (and VFS_VFSCONF, but
that has the same value and should go away).
The problem happens because NFS is the first vfs (in sys/conf order) so it
gets type number 0 and conflicts harmfully with VFS_GENERIC which is also 0.
The conflict is apparently harmless in the usual case when another vfs
gets type number 0, because nfs is the only vfs that has sysctls.
