Recent TTS change altered how the TextToSpeech.synthesizeToFile method operates. Previously, synthesis service was responsible for creating output file. Now, client API creates a file and then sends opened file descriptor using ParcelFileDescriptor. On service side, I forgot to keep a reference to a ParcelFileDescriptor object. When GC was removing it, it was closing underlying file descriptor, resulting in a EBADF error for all following writes to the output file. This change makes use of a ParcelFileDescriptor.AutoCloseOutputStream to keep a reference to the ParcelFileDescriptor. It will be referenced until we are done with writing.
