Justin T. Gibbs 471e5fa096 John Dyson's patches (and a few from me too) to LFS to use a different
buffering scheme and make it more in tune with FreeBSD's vfs_bio
implementation.  The filesystem seems fairly stable, but I wouldn't recommend
it to anyone not willing to experience problems.  This is very green code and
has the limitation that YOU CAN ONLY HAVE ONE LFS PARTITION MOUNTED AT A TIME.

What LFS is good for:

	Non fsynced writes	FASTER THAN FFS
	Large deletions		Increadibly fast

Reads are a little bit slower than FFS right now, but that is a factor of
how under optimized this code is.  LFS should in theory perform at least as
well as FFS under fsync (iozone) type loads, and this is what I'm currently
working on.
