StageFrightRecorder: do not use meta-data mode for software encoders
Camera HAL v1 uses vendor-specific camera-source meta-data mode, but
software encoders use generic gralloc-source mode, so they are not
compatible.

Add framework support for camcorder zoom.
The purpose of ICameraRecordingProxy and ICameraRecordingProxyListener is to
allow applications using the camera during recording.
Camera service allows only one client at a time. Since camcorder application
needs to own the camera to do things like zoom, the media recorder cannot
access the camera directly during recording. So ICameraRecordingProxy is a proxy
of ICamera, which allows the media recorder to start/stop the recording and
release recording frames. ICameraRecordingProxyListener is an interface that
allows the recorder to receive video frames during recording.
ICameraRecordingProxy
startRecording()
stopRecording()
releaseRecordingFrame()
ICameraRecordingProxyListener
dataCallbackTimestamp()
The camcorder app opens the camera and starts the preview. The app passes
ICamera and ICameraRecordingProxy to the media recorder by
MediaRecorder::setCamera(). The recorder uses ICamera to setup the camera in
MediaRecorder::start(). After setup, the recorder disconnects from camera
service. The recorder calls ICameraRecordingProxy::startRecording() and
passes a ICameraRecordingProxyListener to the app. The app connects back to
camera service and starts the recording. The app owns the camera and can do
things like zoom. The media recorder receives the video frames from the
listener and releases them by ICameraRecordingProxy::releaseRecordingFrame.
The recorder calls ICameraRecordingProxy::stopRecording() to stop the
recording.
The call sequences are as follows:
1. The app: Camera.unlock().
2. The app: MediaRecorder.setCamera().
3. Start recording
(1) The app: MediaRecorder.start().
(2) The recorder: ICamera.unlock() and ICamera.disconnect().
(3) The recorder: ICameraRecordingProxy.startRecording().
(4) The app: ICamera.reconnect().
(5) The app: ICamera.startRecording().
4. During recording
(1) The recorder: receive frames from ICameraRecordingProxyListener.dataCallbackTimestamp()
(2) The recorder: release frames by ICameraRecordingProxy.releaseRecordingFrame().
5. Stop recording
(1) The app: MediaRecorder.stop()
(2) The recorder: ICameraRecordingProxy.stopRecording().
(3) The app: ICamera.stopRecording().

Implemented frequent read returns for quick stop in time lapse.
If the frame capture interval is large, read will block for a long time.
Due to the way the mediaRecorder framework works, a stop() call from
mediaRecorder waits until the read returns, causing a long wait for
stop() to return. To avoid this, we return a copy of the last read
frame with the same time stamp if a frame is not available quickly.
This keeps the read() call from blocking too long. This method is
triggered when startQuickReadReturns() is called on
CameraSourceTimeLapse.
In the still camera case, also using waitRelative on Condition
instaed of sleeping, so that we can wake it up.
Also for the idle check instead of sleeping, we now wait on a
condition variable, which is woken up when the last takePicture
callback gets called.

Moving decision to use still camera to CameraSourceTimeLapse
CameraSourceTimeLapse now decides whether to use still or video
camera automatically. It checks if the passed in size is a valid
preview size and if it is, then uses the video camera else uses
the still camera.
Removed from StagefrightRecorder the support to set parameter
useStillCameraForTimeLapse.

Support for video size to be different from captured picture size.
Adding support to allow video size to be different than the supported
picture sizes. A picture size larger than the demanded video size is
chosen. Captured pictures are then cropped to the size of the desired
video size. Cropping is done from the the center portion of the picture.

Restart preview after each takePicture is done.
Preview is called when CAMERA_MSG_COMPRESSED_IMAGE is recieved by
dataCallback(). It needs to be started as a new thread so that the
callback can return, and the camera can know that takePicture() is
done.

Adding support for timelapse capture using still camera's takepicture.
Also moving entire implementation into a new class CameraSourceTimeLapse
which inherits from CameraSource.
For timelapse capture using still camera, we start a thread which runs a
loop in which it calls Camera::takePicture() and then sleeps until the next
frame should be captured.
The function dataCallback() handles the callback from the camera with the
raw image data. This function copies the data and creates an artificial
timestamp corresponding to one frame time ahead of the last encoded frame's
time stamp. It then calls dataCallbackTimestamp() of the base class which
will think that it recieved the frame from a video camera and proceed as usual.
For moving the implementation to the subclass CameraSourceTimeLapse, added a
few virtual functions to CameraSource, which do the current thing for the base
class, but specialized things for CameraSourceTimeLapse.
E.g. startCameraRecording() in the base class just calls mCamera->startRecording(),
while in CameraSourceTimeLapse it may start a thread for the still camera case.
