  uuid: Change semantics of uuid_is_partial_string().

Until now, uuid_is_partial_string() returned the number of characters at
the beginning of a string that were the beginning of a valid UUID.  This
is useful, but all of the callers actually wanted to get a value of 0 if
the string contained a character that was invalid for a UUID.  This makes
that change.

Examples:

  "123" previously yielded 3 and still does.
  "xyzzy" previously yielded 0 and still does.
  "123xyzzy" previously yielded 3, now yields 0.
  "e66250bb-9531-491b-b9c3-5385cabb0080" previously yielded 36, still does.
  "e66250bb-9531-491b-b9c3-5385cabb0080xyzzy" previously yielded 36, now 0.
