This commit moves any tables specific to the encoder from aacenc and aaccoder to a separate file called 'aacenctab.c/.h'. This was done as a clean up attempt as the encoder was filled with tables pasted in between functions which made it confusing to follow and track where each table and definition had been used. This commit solves this by simply exporting the smaller tables out to the aacenctab.h while the larger ones are compiled using aacenctab.c and are referenced from the header file.
