Martin Storsjö e8cbdb9adb libfdk-aacdec: Allow explicitly disabling the DRC reference level option 
Previously, it was always left in the automatic mode, if the option
was set to the only special (negative) value. Now there's two separate
special values for this option, -1 for automatic (metadata based)
and -2 for explicitly disabled.
