The macros defined at bw_fixed are important mathematical definitions, specifying masks to get the fractional part and the maximum and minimum values of I64. In order to enable unit tests for bw_fixed, it is relevant to have access to those macros. This commit moves the macros to the header file, making it accessible to future unit tests.
