I did some more kibitzing here and there, and committed. Thanks everyone!

I agree the new maps should just replace the old maps altogether, so 
committed that way. I also moved the combined map files to the same .map 
files as the main radix trees. Seems more clear that way to me.

I changed the to/from_unicode properties back to a single direction 
property, with Perl constants BOTH, TO_UNICODE and FROM_UNICODE, per 
your alternative suggestion upthread. Seems more clear to me.

It would be nice to run the map_checker tool one more time, though, to 
verify that the mappings match those from PostgreSQL 9.6. Just to be 
sure, and after that the map checker can go to the dustbin.
