Mark udf(4) MPSAFE and add support for shared vnode locks during pathname
lookups:
- Honor the caller's locking flags in udf_root() and udf_vget().
- Set VV_ROOT for the root vnode in udf_vget() instead of only doing it in
  udf_root().
- Honor the requested locking flags during pathname lookups in udf_lookup().
- Release the buffer holding the directory data before looking up the vnode
  for a given file to avoid a LOR between the "udf" vnode locks and
  "bufwait".
- Use vn_vget_ino() to handle ".." lookups.
- Special case "." lookups instead of calling udf_vget().  We have to do
  extra checking for the vnode lock for "." lookups.
