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.

8f24c12be7 ac3dec: Don't consume more data than the actual input packet size 
This was handled properly in the normal return case at the end
of the function, but not in this special case.

Returning a value larger than the input packet size can cause
problems for certain library users.

Returning the actual input buffer size unconditionally, since
it is not guaranteed that frame_size is set to a sensible
value at this point.
