Ah, this seems to require putting encnames.o and wchar.o in src/common's
Makefile and moving pg_encoding_mbcliplen() from mbutils.c to wchar.c.
Fairly simple.

(There's a little bit of additional fallout because libpq also has
encnames/wchar in its roster, but I think this means we can just remove
them from there and let them be acquired via libpgcommon.)
