Camera clients must be aware of any configured streams
that can support offline processing mode.
A few corner cases that need to be considered:
- Composite streams can support offline mode only
when all internal streams support it as well.
- Streams that use the internal camera buffer manager
will not have support for offline mode.
- Shared streams are also unsupported in offline mode.

Add physical camera ID in OutputConfiguration so that the application
can optionally set physical camera id for an output stream.

The Camera API needs to support the dynamic attach/detach of extra
output surfaces to a given camera stream.

- 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.

- Refactor the OutputConfiguration to contain isDeferred and isShared
flag, and not contain NULL surface.
- Unify the handling of deferred surface and shared surface.

- 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
