> Remove AudioBuffersState class.
> 
> The AudioBuffersState object doesn't appear to be necessary anymore.
> Most code either completely ignores this information or doesn't actually
> care about the difference between pending_bytes and hardware_delay_bytes.
> Also usually only one of the 2 fields was actually being used at a time.
> This change removes the class and simply uses an int that represent the
> total number of delay bytes.
