Subject: [PATCH] unistr/u*-chr: prepare for multibyte tests

* modules/unistr/u16-chr-tests: Depend on u32-to-u16.
* modules/unistr/u8-chr-tests: Depend on u32-to-u8.
* tests/unistr/test-chr.h: Build initial version as UCS-4 then convert.
* tests/unistr/test-u16-chr.c, tests/unistr/test-u32-chr.c,
tests/unistr/test-u8-chr.c: Define U32_TO_U.
