This CL is the first in a series of CL's that will extract the
zoom code from WebView and put it into ZoomManager. This initial
CL only extracts the on-screen zoom controls and required variables
into the ZoomManager. Since the on-screen controls are well defined
I put them into their own class called ZoomControls.
All of WebView's zoom interactions are handled by the ZoomManager.
The ZoomManager can then handle the request internally or as in the
case of on-screen controls pass the request to another class.

The problem is due to a too big difference between the buffer size used at the hardware interface and at the A2DP interface.
When no resampling occurs we don't notice problems but the timing is very tight. As soon as resampling is activated, the AudioTrack underruns.
This is because the AudioTrack buffers are not resized when moving the AudioTrack from hardware to A2DP output.
The AudioTrack buffers are calculated based on a hardware output buffer size of 3072 bytes. Which is much less than the A2DP output buffer size (10240).
The solution consists in creating new tracks with new buffers in AudioFlinger when the A2DP output is opened
instead of just transfering active tracks from hardware output mixer thread to the new A2DP output mixer thread.
To avoid synchronization issues between mixer threads and client processes, this is done by invalidating tracks
by setting a flag in their control block and having AudioTrack release the handle on this track (IAudioTrack)
and create a new IAudioTrack when this flag is detected next time obtainBuffer() or start() is executed.
AudioFlinger modifications:
- invalidate the tracks when setStreamOutput() is called
- make sure that notifications of output opening/closing and change of stream type to output mapping are sent synchronously to client process.
This is necessary so that AudioSystem has the new stream to output mapping when the AudioTrack detects the invalidate flag in the client process.
Previously their were sent when the corresponding thread loop was executed.
AudioTrack modifications:
- move frame count calculation and verification from set() to createTrack() so that is is updated every time a new IAudioTrack is created.
- detect track invalidate flag in obtainBuffer() and start() and create a new IAudioTrack.
AudioTrackShared modifications
- group all flags (out, flowControlFlag, forceReady...) into a single bit filed to save space.

When showing a progress bar instance more than once
it will not animate after the first time.

Fix sampleTable instantiation, this makes sure that the sample table refers to the custom datasource that caches the metadata to prevent needless seeking.
It no longer makes sense to create type info from Java since this
cannot be exported to scripts. The new flow is in the opposite direction.
