In kern_physio.c fix tsleep priority messup.

In vfs_bio.c, remove b_generation count usage,
	remove redundant reassignbuf,
	remove redundant spl(s),
	manage page PG_ZERO flags more correctly,
	utilize in invalid value for b_offset until it
		is properly initialized.  Add asserts
		for #ifdef DIAGNOSTIC, when b_offset is
		improperly used.
	when a process is not performing I/O, and just waiting
		on a buffer generally, make the sleep priority
		low.
	only check page validity in getblk for B_VMIO buffers.

In vfs_cluster, add b_offset asserts, correct pointer calculation
	for clustered reads.  Improve readability of certain parts of
	the code.  Remove redundant spl(s).

In vfs_subr, correct usage of vfs_bio_awrite (From Andrew Gallatin
	<gallatin@cs.duke.edu>).  More vtruncbuf problems fixed.
