Backport (simple cherry-pick) d33019030c1f0cddca557f9659e3c471bde0e6a9
to gingerbread.

Implement RFC3484 policy table changes from draft-ietf-6man-rfc3484-revise-01.

The changes in a nutshell:

 - Handle v4-mapped as different from v4-compat (this was probably
   an existing bug in our code).
 - Add policy entries for ULA, above most everything else.
 - Put v4-compat, old-style IPv6 site-local and 6bone addresses
   way down in the preference table.

The rest is just shuffling numbers around (no actual changes to
priority).
