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

Log Message:
Add a sleeper count, to prevent the cleaner from panicing the kernel
when the filesystem is unmounted, relocking the Ifile when its lock is
draining.  (We can't use vfs_busy() since the process is sleeping for a
good long time.)  Clean up / organize lfs.h, while I'm here.

In lfs_update_single, assert that disk addresses are either negative, or
are still positive when converted to int32_t, to prevent recurrence of a
negative/positive block problem.
