Previously, onLoadLanguage was executed without minding synthesis queue.
Now onLoadLanguage is queued item, so it won't be executed before the items
on the queue (previously TTS could receivecall to onLoadLanguage
while synthesizing in completly different language).
I've divided SpeechItem into ControlSpeechItem and UtteranceSpeechItem.
Utterance one dispatches callbacks about synthesis progress.

Previously, getLanguage returned language set on the TTS service side.
In most cases client wants to receive value that was set on the Client side
(value that was set by last call to the setLanguage). That's true, for
example, for android settings app.
This is not an issue if there's only one client, or when all clients use the same
language. In that cases, service and client languages are in sync.
But if there are multiple clients using different languages, getLanguage might
return values that were not set by the client - and that's not what most of clients expect
to happen.

ITextToSpeechService.setCallback (service rpc call) is no longer
executed on UI thread.
I kept OnInitListener.onInit being called on the UI thread. It's
not specified explicitly, but I don't want to introduce subtle
bugs.

- Sets the service connection to null when unbindService is called,
instead of in onServiceDisconnected. This avoids a double disconnect
if a call to onServiceConnected is received before a call to
onServiceDisconnected.
- Extended synchronize on runAction error handling and reconnection.
This prevents from reconnecting N times if N>1 threads enter this method
while there's issue with TTS service.

- Fixes some log spam when done() is called twice.

Will be seen when createStreamingAudioTrack() returns null,
which will happen if the audioflinger / audiomanager are unhealthy.
Also removes some confusing synchronization from this class.

The TTS instantiated from here shouldn't clobber any
existing TTS objects opened within the same package context.
Ideally, the TTS API should work fine with multiple TTS object
instances within the same package context but making that happen
correctly is a larger change.

(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.

When synthesized files are written to app private data dirs,
they are written with owner/grp set to the TTS engine and
are inaccessible by the app itself. This is a reported regression
from gingerbread behaviour. Note that the dir in which the
engine writes files is itself already world writable.

This is made necessary by a bug when the utterance is smaller
than the audio buffer size. In that case, we call stop() to
flush the audio to the mixer, but that causes the playstate to
be set to stopped though some audio is still being mixed. This
breaks our waiting loop.
We now wait a fixed amount of time for such short utterances
and do not observe the playback head position.

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.

AudioTrack buffer. This forces pending buffers to
get mixed.
(b) Introduce a minimum sleep time to avoid spinlocks
if they system is busy

being stopped.

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.
