at MAXPARTITIONS/OLDMAXPARTITIONS in kernel sources, so that it wouldn't
need to be specified separately in MAKEDEV.conf
change platform MAKEDEV.conf to contain only MD targets and nothing else;
simplify the parsing in MAKEDEV.awk accordingly
this contains information about disk partitions used by platform,
and MD MAKEDEV targets, such as 'init', MD part of 'all',
as well as any other MD-specific targets not covered by MAKEDEV.tmpl
any pipes and running other commands (eg dd).
Measurable speeds up creating pseudo ttys.
(there has to be a better way than editing 51 files! - tedious at only
6 key presses per file)
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
