Modified Files:
	src/sys/ufs/lfs: lfs.h lfs_alloc.c lfs_balloc.c lfs_bio.c lfs_segment.c
	    lfs_vfsops.c lfs_vnops.c
	src/sys/ufs/ufs: ufs_readwrite.c

Log Message:
Keep per-inode, per-fs, and subsystem-wide counts of blocks allocated through
lfs_balloc(), and use that to estimate the number of dirty pages belonging
to LFS (subsystem or filesystem).  This is almost certainly wrong for
the case of a large mmap()ed region, but the accounting is tighter than
what we had before, and performs much better in the typical case of pages
dirtied through write().
