MD disktab where possible (everything but vax)
the MD disktab was often either empty, or contained entries even for disks
which support geometry autodetection (SCSI), and/or non-interesting/long
obsolete entries
the old records are still available in example disktab in
/usr/share/examples/disktab/disktab in case anyone would need them
for all platforms.
- remove now unnecessary replicated code in the various snap_md_post targets
- remove snap_md_pre; nothing uses it any more
- use ${NETBSDSRCDIR} and ${KERNSRCDIR} as appropriate
needed to fully support the "new distrib world order"):
* remove unnecessary trailing ;
* clean up whitespace
* remove unnecessary chown root or chgrp wheel directives; older code here

* don't barf when we have fdesc mounted; just skip the devices fdesc provides
* when making directories, don't use -p and don't redirect stdout to /dev/null
* add /dev/fd/* support [hp300]
* convert to new pty generation [hp300]
(prevents spurious warning for mfs /dev, amongst other things)
- for mipsco, news68k, newsmips: ensure that "umask 77" is run after $0.local
- for playstation2: add local) target, and use in all) (for consistency)
