This left number/double values completely uncovered in test-visitor-serialization tests. Fixing this exposed a bug in our handling of large whole number values in QEMU's JSON parser which is now fixed. Simplify the code while we're at it by dropping the calc_float_string_storage() craziness in favor of GStrings.
