There is a macro buffered_String_method_with_retry which does this
little variable buffer dance that is sometimes needed in the ICU4C
API. This macro is the same thing, except the end result is not a
UTF8 string, but a UChar string.
This will come in handy in Issue #141, since
unum.h
comes withquite a few methods that fit this general pattern.
