machdep.guessed_bootdev, and add code to sysctl to parse its value
and give a (not necessarily correct) name to the device we booted
from (the main motivation for this code is to use the info in the
PicoBSD boot scripts, and the impact on the kernel is minimal).
NOTE: the information available in bootdev is not always reliable,
so you should not trust it too much. The parsing code is the same
as in boot2.c, and cannot cover all cases -- as it is, it seems to
work fine with floppies and IDE disks recognised by the BIOS. It
_should_ work as well with SCSI disks recognised by the BIOS.
Booting from a CDROM in floppy emulation will return /dev/fd0 (because
this is what the BIOS tells us).
Booting off the network (e.g. with etherboot) leaves bootdev unset so
the value will be printed as "invalid (0xffffffff)".
Finally, this feature might go away at some point, hopefully when we
have a more reliable way to get the same information.

volumes are available, instead of getting stuck in a loop calling
getvol(). Normally restore in 'x' or 'i' modes will ask for a new
(earlier) volume when the current inode number on the tape is greater
than the last inode to be restored, since there can be no further
inodes of interest on that volume. However we don't want to change
volumes in this case either if the user explicitly said that there
are no more tapes, or if we are looking at the first volume.
When no more volumes are available but there are still inodes that
we have not found, we now just fall through to the code that prints
out a list of any missing files, so the restore completes normally.
Also simplify the logic a bit by always returning to the start of
the main for(;;) loop whenever the volume has changed.
This should completely fix the "Changing volumes on pipe input" bug
that is often observed when restoring dumps of active filesystems.

to multi-volume restores:
- In findinode(), keep a copy of header->c_type so that we don't
exit the do-while loop until we have processed the current header.
Exiting too early leaves curfile.ino set to 0, which confuses
the logic in createfiles(), so multi-volume restores with the
'x' command don't work if you follow the instructions and supply
the tapes in reverse order. This appears to have been broken
by CSRG revision 5.33 tape.c (Oct 1992).
- The logic in getvol() for deciding how many records to skip after
the volume header was confused; sometimes it would skip too few
records and sometimes too many, leading to "resync restore"
warnings and missing files. Skip to the next header only when
the current action is not `USING'. Work around a dump bug that
sets c_count incorrectly in the volume header of the first tape.
Some of the problems here date back to at least 1991.
- Back out revision 1.23. This appeared to avoid warnings about
missing files in the 'rN' verification case, but it made the
problems with the 'x' command worse by stopping getvol() from
even attempting to find the first inode number on the newly
inserted tape. The bug it addressed is fixed by correcting the
skipping logic as described above.
- Save the value of `tpblksread' in case the wrong volume is
supplied, because it is incremented each time we read a volume
header. We already saved `blksread' for the same reson.
Normally trewind() performs a close-open-close cycle to rewind the
tape when closing the device, but this is not ideal for fifos. We
now skip the final open-close if the output descriptor is a fifo.
