The names of float format family are changed.
old new
dec -> f64
MSGPACK_OBJECT_DOUBLE -> MSGPACK_OBJECT_FLOAT
msgpack::type::DOUBLE -> msgpack::type::FLOAT
Client codes could have compile errors when it use dec, MSGPACK_OBJECT_DOUBLE or msgpack::type::DOUBLE.
The best way to fix such errors, update client code. If it can't, set MSGPACK_USE_LEGACY_NAME_AS_FLOAT macro.
Then both old names and new names are available.
Fixed inttypes.h inclusion problem on MSVC.
Fixed msgpack_object_print implementation using PRIi8, PRIi64, and PRIu64.
If 64bit print is not supported on fprintf, dispatch to fallback print.
