except for places where people forget to update one of them. We now
collect only one set of stats for both of these routines. Other
changes in this commit include:
- Start acquiring Giant again in vn_fullpath(), since it is required
when crossing a mount point.
- Expand the scope of the cache lock to avoid dropping it and
picking it up again for every pathname component. This also
makes it trivial to avoid races in stats collection.
- Assert that nc_dvp == v_dd for directories instead of returning
an error to userland when this is not true. AFAIK, it should
always be true when v_dd is non-null.
- For vn_fullpath(), handle the first (non-directory) vnode
separately.

dropping the cache lock. This protects the vnodes identity until we
have locked it.

we lookup the last component.
- Acquire VFS_ROOT and dp locks based on the cn_lkflag.

- Avoid an extra mutex acquire and release in the common case of vgonel()
by checking for OWEINACT at the start of the function.
- Fix the case where we set OWEINACT in vput(). LK_EXCLUPGRADE drops our
shared lock if it fails.
