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.
