Camera: Fix passing video native handle for 64-bit app
Add new binder calls to pass video native handle so the video native
handle can be passed between 32-bit and 64-bit processes.
Remove problematic code that used IMemory to pass video native
handle because the sizes of VideoNativeMetadata are different in
32-bit and 64-bit processes.

Camera: Fix client permission check
Modify StageFright's CameraSource to forward calling PID as
client PID when connecting to CameraService so CameraService
can check if the client PID has permission to use camera.
Change CameraService to check calling UID is trusted before
using the passed in client PID and client UID to verify permission.

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().

Make sure that key frame is generated for timelapse video recording if there are at least two input video frames from camera source.
This will fix the stop failure issue where we have to wait n * time_interval before a key frame can be received by the file writer, where
o n is the actual number of buffers advertised by the video encoder
o time_interval is the interval settings for timelapse video recording
specifying the time distance between neighboring input video frames
The fix includes two parts:
o OMXCodec will not submit all n buffers at one time, but instead submit one input
frame at one time if it become available.
o Timelapse camera source made available the first two input frames and do not skip
them so that the first compressed output frame data can be received regardless
the specified time_interval

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.

Call startPreview after stopping for mUseStillCameraForTimeLapse=true case.
In the case when stop is pressed after takePicture has been called
but the CAMERA_MSG_COMPRESSED_IMAGE message from camera has not yet
been received, preview was not getting restarted. The reason was that
CameraSource::stop sets the camera listener to NULL and hence the
dataCallback() function which handles the CAMERA_MSG_COMPRESSED_IMAGE
message and restarts preview never got called.

use usleep instead of sleep.
Minor bugfix. sleep doesn't take fractional value for seconds, so use
usleep instead of sleep for sleeping small times.

Implementing getSupportedPictureSizes
Go through all the supported picture sizes and choose the smallest one with
both dimensions higher than the passed in video width and height.

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.

Allowing setting of time lapse parameters through MediaRecorder.java
added setTimeLapseParameters() to MediaRecorder.java and SetParameter support
in StagefrightRecorder to allow enabling time lapse and setting the corresponding
parameters.

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.
