Log Message:
Add a flag to VOP_LISTEXTATTR(9) so that the vnode interface can tell the
filesystem in which format extended attribute shall be listed.

There are currently two formats:
- NUL-terminated strings, used for listxattr(2), this is the default.
- one byte length-pprefixed, non NUL-terminated strings, used for
  extattr_list_file(2), which is obtanined by setting the
  EXTATTR_LIST_PREFIXLEN flag to VOP_LISTEXTATTR(9)

This approach avoid the need for converting the list back and forth, except
in libperfuse, since FUSE uses NUL-terminated strings, and the kernel may
have requested EXTATTR_LIST_PREFIXLEN.
