to avoid compat problems with old ffsv1 by reuse of the old FS_SWAPPED
value for FS_FLAGS_UPDATED, and use of new, larger fields:
- Don't use FS_FLAGS_UPDATED to see if we need to update new fields from
old fields in ffsv1 case.
- when writing back the superblock, copy back the flags to the old location
if only old flags are set (FS_FLAGS_UPDATED won't be set in this case)
in ffsv1 case.

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.
