Decide whether to release rather than flush in onInputFormatChanged

Browse Source 
- This change removes the last piece of logic that could cause deferred
  codec release (i.e., where the decision to release was made in
  processEndOfStream rather than in onInputFormatChanged.
- After this change, whether the codec will be released as a result of
  a format change is always established in onInputFormatChanged.
