Camera: Rework StreamSplitter for camera use cases
- Merge notifyRequestedSurfaces into getBufferLocked, so that during
getBufferLocked, the stream splitter gets to know which outputs the
current request is on.
- Reserve buffer slot in the output queue during getBufferLocked instead
of during onFrameAvailable. So if there is no slot/buffer available, no
new request is sent to HAL. This aligns with current cameraservice logic.
Do not hold the lock while calling attachBuffer to output queue because
it could block for a slow consumer.
- Instead of setting the consumer buffer count of input buffer queue to
maximum of all shared outputs, set it to sum of them. By doing this,
In the case of a slow consumer, other consumers sharing the same stream
won't be impacted.
- Handle the case where onBufferReleased not being fired for buffer
replaced by attachBuffer/queueBuffer.
- Add function to check the return value of onFrameAvailable so that
when output is abandoned, the error code is propagated back to
queueBuffer.
Test: Camera CTS, and CTS with StreamSplitter enabled for all
implementation defined use cases.

Camera: StreamSplitter: Return overwritten buffer to input
For Async buffer queue, if a pending buffer is overwritten by an
incoming buffer, onBufferReleased callback isn't called. But the stream
splitter depends on the onBufferReleased to return buffer to input.
Fix the problem by checking the bufferReplaced flag in
QueueBufferOutput.

Camera: Combine handling of deferred surface and shared surface
- Refactor the OutputConfiguration to contain isDeferred and isShared
flag, and not contain NULL surface.
- Unify the handling of deferred surface and shared surface.
Test: Camera CTS, and manual testing of GoogleCamera use cases

camera2: Add support for secondary surface for stream
- Enhance OutputConfiguration to contain multiple surfaces for one
underlying stream.
- Create Camera3SharedOutputStream to handle streams with multiple
surfaces.
- Create Camera3StreamSplitter to handle buffer flows between camera and
multiple consumers.
Test: cts, and manually test camera preview/snapshot/recording
