Implement time markers for TTS.
The service can inform the framework at which frame a part of the input
is spoken, and that information is then relayed to the client.
This can be used to highlight the currently spoken word/sentence or to
resume synthesis requests at the start of the last word/sentence.

Restrict audioformat to 8bit, 16bit or float PCM with an annotation and
a warning.
TextToSpeech.synthesizeToFile has only ever worked with 8bit and 16bit
PCM. In case of float PCM an invalid file would be generated and in case
of other encodings the TTS engine would crash.
Also add more annotations to SynthesisCallback.

Add new TTS API.
Much of existing API is reused (mostly on the service side). The new API
provides better support for network-based synthesis, defines explicit
synthesis fallback support, has better error handling, allows for multiple
different voices per locale, features enumeration and custom extensions
on a voice level and many more.
If a service does not provide a V2 implementation, a basic adapter
from V2 to existing V1 implementation is provided.

Simplify the implementation of AudioPlaybackHandler.
Now uses a queue of runnables, one per synthesis. Also
introduce an abstraction that wraps AudioTrack that implements
the blocking semantics that we desire.

Fix regressions in TTS completion callbacks.
(a) onUtteranceCompleted should be called on errors too. Also,
fix up the error handling so that onUtteranceCompleted is
always called.
(b) Don't treat empty utterances as errors, and let the engine
synthesize them, as before.

Don't allow TTS engines to synthesize too for ahead.
For each synthesis request, we inspect the number of
bytes of audio that have not been written to the mixer yet
and if that is above a certain threshold (currently 500ms),
we block the synthesis thread.

Remove the completeAudioAvailable API.
Measurements have shown that the audio track in streaming mode
is pretty efficient as is, thanks to dalvik's JNI implementation.
Also, in streaming mode write( ) blocks until all data has been
copied to the mixer, which is the kind of behaviour we want so
that we don't have to explicitly block in our code. Also,
the java AudioTrack is thread-safe with respect to stop( ) calls
during write, which means we can do everything completeAudioAvailable
did, just as efficiently without it.

Implement QUEUE_FLUSH and QUEUE_DESTROY addition modes.
Note that this change is slightly more flexible, it defines
a priority for each playback request. We needn't really throw
away synthesis requests from other apps. We could just play
them after higher priority ones (for e.g from talkback).
