Suppose applications call autoFocus in CAF picture mode. If
CAF is in the middle of scanning, the picture is very likely to
be blurry. Change focus callback to return when the scanning
finishes.

Hardware video stabilization reduces camera shake in preview
and in recorded videos. It has no effect on still image capture.
Convenience accessor methods hidden for now.

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().

Adds a new camera parameter for locking auto-white balance to its
current value. Also adds a function for checking if auto-white balance
lock is supported by the current platform. Lock semantics match that
of the auto-exposure lock.

This patch changes CameraService to load a camera HAL module, instead of
linking directly against a library that implements the CameraHardwareInterface
class.
CameraHardwareInterface no longer defines the API to the camera HAL. Instead,
this is now in HAL header hardware/camera.h. We keep CamerHardwareInterface as
a class local to CameraService, which wraps around the new HAL calls. In the
future, we may remove this class entirely and have CameraService call the HAL
methods directly.

We define struct CameraInfo in this camera/Camera.h, even though an identical
struct camera_info is defined in hardware/camera.h (but not in
hardware/camera_defs.h). We may not export struct definitions from the HAL
into headers which may find their way into the NDK.
This commit also renames FRAME_CALLBACK_FLAG_xxx to CAMERA_FRAME_CALLBACK_xxx.

Weigh values must be less than 1000, but have no restriction on their
sum. Weights should be interpreted as per-pixel values, meaning larger
areas will have more influence over focus/metering than smaller areas
of the same weight.

Methods getNumberOfVideoBuffers() and getVideoBuffer() as well as struct
image_rect_struct are no longer used (instead, the necessary information is
passed through ANativeWindow.)

This change enables the use of a SurfaceTexture in place of a Surface as
the destination of camera preview frames.

Now overlay does ROT_90 before FLIP_V or FLIP_H. It should be FLIP_V
or FLIP_H first. The formula should be changed after overlay is fixed.

This constant is not public yet. Continuous autofocus should
behave differently in still camera and camcorder. In camcorder,
lens movement may be more smooth. And the triggers to start a
new focus search may be different. If there is a need,
FOCUS_MODE_CONTINUOUS_PHOTO can be added in the future.

Added CAMERA_CMD_PLAY_RECORDING_SOUND command type to play recording
sound through sendCommand. This is currently needed by time lapse
recording using still mode capture, which disables the shutter sound
but needs to play the recording sound.

- Added enum CAMERA_CMD_ENABLE_SHUTTER_SOUND which corresponds to
command type for enabling/disabling shutter sound.
- The implementation checks if it is legal to disable shutter sound.
If it is, then any process can disable the sound. If not, then only
the mediaserver process is allowed to do this. Currently time lapse
capture needs this functionality to disable shutter sound when still
mode is used to capture time lapse video.

This change makes the camera HAL interface take an ANativeWindow interface from
which all the camera preview buffers will be allocated. The framework code
running in application processes now passes a Surface object rather than an
ISurface to the camera server via Binder when setting the preview surface. The
camera server then forwards that Surface object (which implements the
ANativeWindow interface) to the camera HAL, which uses it to communicate with
SurfaceFlinger to allocate the camera preview buffers.
