Andreas Cadhalpun	7b05b5093e	ac3dec_fixed: always use the USE_FIXED=1 variant of the AC3DecodeContext The AC3DecodeContext has a float (USE_FIXED=0) and an integer (USE_FIXED=1) variant, both of which can be present in the same binary. This is not only very confusing, but it also breaks horribly, when one variant is used by code expecting the other. This currently happens, because eac3dec.c is only compiled for the float variant, but also used from ac3dec_fixed.c, which uses the integer variant. The result is memory corruption, leading to crashes. So compile eac3dec.c once for each variant and adapt it, so that it works with the integer variant.

Jean-Francois Thibert	12df9b9a15	Improved AC3 decoder level support (heavy drc, dialnorm) Added support for AC3 heavy dynamic range compression used to restrict the output range and added a setting to specify the output target level and use the dialog normalization field to apply it in the digital domain.
