Here is the rebased patch.

v4-0001 implements uuid <-> bytea casting
v4-0002 implements base32 encoding/decoding

Unless I missed something, 0001 is ready to be merged.

I only rebased v3 and improved the commit messages, but I didn't
account for Masahiko Sawada's feedback for 0002. Andrey, are you still
working on this or others can pick it up?

The patch is not on the commitfest, so I'm about to add it.
