With the proposed approach, we'll keep binary compatibility, so
this is not much of an issue.

Note: Changes to the binary interface can be done in minor releases,
but we should make sure that it's not possible to load an extension
compiled with 3.1 in 3.2 to prevent segfaults and buffer overruns.

The change affects the Unicode type database which is implemented
in unicodectype.c, not the Unicode database, which already uses UCS4.
