Undo part of the ktrace/lwp changes. In particular:
...
* Remove the "lwp *" argument that was added to vget(). Turns out
that nothing actually used it!
* Remove the "lwp *" arguments that were added to VFS_ROOT(), VFS_VGET(),
and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted
above, didn't use it).
* Remove all of the "lwp *" arguments to internal functions that were added
just to appease the above.

Make LFS work better (though still not "well") as an NFS-exported
...
filesystem (and other things that needed to be fixed before the tests
would complete), to wit:
* Include the fs ident in the filehandle; improve stale filehandle checks.
* Change definition of blksize() to use the on-dinode size instead of
the inode's i_size, so that fsck_lfs will work properly again.
* Use b_interlock in lfs_vtruncbuf.
* Postpone dirop reclamation until after the seglock has been released,
so that lfs_truncate is not called with the segment lock held.
* Don't loop in lfs_fsync(), just write everything and wait.
* Be more careful about the interlock/uobjlock in lfs_putpages: when we
lose this lock, we have to resynchronize dirtiness of pages in each
block.
* Be sure to always write indirect blocks and update metadata in
lfs_putpages; fixes a bug that caused blocks to be accounted to the
wrong segment.

PR/1796: John Kohl: statfs misbehaves under chrooted environments.
...
- Under chroot it displays only the visible filesystems with appropriate paths.
- The statfs f_mntonname gets adjusted to contain the real path from root.
- While was there, fixed a bug in ext2fs, locking problems with vfs_getfsstat(),
and factored out some of the vfsop statfs() code to copy_statfs_info(). This
fixes the problem where some filesystems forgot to set fsid.
- Made coda look more like a normal fs.
