	src/sys/ufs/lfs: lfs.h lfs_extern.h lfs_segment.c lfs_subr.c
	    lfs_syscalls.c lfs_vfsops.c lfs_vnops.c

Log Message:
Add an lfs_strategy() that checks to make sure we're not trying to read
where the cleaner is trying to write, instead of tying up the "live"
buffers (or pages).

Fix a bug in the LFS_UBC case where oversized buffers would not be
checksummed correctly, causing uncleanable segments.

Make sure that wakeup(fs->lfs_iocount) is done if fs->lfs_iocount is 1
as well as 0, since we wait in some places for it to drop to 1.

Activate all pages that make it into lfs_gop_write without the segment
lock held, since they must have been dirtied very recently, even if
PG_DELWRI is not set.
