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

Log Message:
Use VONWORKLST as a heuristic for vnode emptiness, rather than exhaustively
checking the memq.

Take greater care not to dirty the Ifile vnode when unmounting the filesystem.
This should fix a "(vp->v_flag & VONWORKLST) == 0" assertion panic in vgonel
that could occur when unmounting.

Do not allow the Ifile to be mapped for writing.
