Add --default-macro-constant-type

* --default-macro-constant-type could be 'signed' or 'unsigned'
  * Its default value is 'unsigned' to use u32/u64
    for C macro constants that fit into the u32/u64 ranges.
  * For old C libraries that use macros as int/long parameter
    and/or return value types, their macros are better declared
    as i32/i64 if the values fit the i32/i64 ranges,
    to be compatible with c_int/c_long types.
    They can use "--default-macro-constant-type signed"
