Apart from making it public (see http://bind10.isc.org/ticket/2638), I
want to consider making it a real class instead of a typedef (of
vector<uint8_t>) with static helper functions.

While we get all vector methods everything 'for free' now, the ones
we'd need should be easy to wrap (assuming the member would still be a
vector), and I think we could make compare simpler as we could make
some guarantees about the contents.

Also, depending on whether we prefer a small extra cycle effort or 1
byte per instance, we could get rid of the double size data (currently
both in first byte and as vector size)
