Missing subtags 003 and 172

As far as I can tell, Mark is right here. Note that the 172 code was not
created purely for statistical purposes,
but is an actual region (even if somewhat unstable). This is distinct from
the codes 199, 432, 722, 778.

This is a purely corrective action w.r.t. the rules in the RFC, and the
question of whether these
codes are useful for language tagging is at this point irrelevant. For that
matter, one may wonder
how the code 001 (World) is useful in language tagging...
