Use /dev/fd0 instead of /dev/fd0a. Add mounting of mcd1 if mcd0
fails when searching for a cdrom drive.

Eliminate warning messages about /sbin/sh /sbin/init and /etc/termcap
when extracting the bin or des archives. Note this is also the
place I fixed the libc.so.1.0 problem a long time ago by adding
a --exclude libc.so.1.0 to the tar command.
pair of crunched binaries that are not built by this, but other than
that it is back to an automated procedure. So many changes it is
hard to describe.
Now minor looks like UU DDDDDD, UU - unit, DDDDDD - density.
If density == 0, CMOS-detect format assumed.
For old users/pgms use fake partitions now, i.e.
ln fd0 fd0[a-h]
No new floppy names added (expect fd? and rfd?),
because don't have agreement yet, so make devices
only for CMOS-detected formats.

added new /dev/wt entries for wt.c version 1.3
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.
Thanks to all who helped to test it on the following hardware:
