When doing round-robin reads from a multi-plex volume, only switch to the
...
next plex if the sector to be read isn't nearby the last read sector.

Change the way the plex lock mutexes work. Previously they were part
...
of the struct plex, which tore apart the mutex linked lists when the
plex table was expanded. Now we maintain a pool of mutexes (currently
32) to be shared by all plexes. This is still a lot better than the
splhigh() method used in other architectures.
Add and clarify comments.

Retire the bogus ioctl DIOCGPART in toto.
...
Once again we can notice that badly thought out hacks ferment and infect
far more code than initially expected.

Stop using the bogus DIOCGPART ioctl, use DIOCGSECTORSIZE and
...
DIOCGMEDIASIZE instead.
The partition type check has been XXX'ed out since we cannot expect
that a BSD disklabel with a type field be available on all platforms.

Change #if VINUMDEBUG to #ifdef VINUMDEBUG. This is a flag, not a variable.
