android: camera_device: Rework CameraStream handling
The CameraDevice::streams_ vector of CameraStream instances is
currently mostly accessed by index. The current implementation
creates all the CameraStream during the first loop that inspects the
camera3_stream instances and then update the index of the
StreamConfiguration associated with the CameraStream during a second
loop that inspects MJPEG streams. A third loop creates the JPEG encoder
associated with camera streams that produce MJPEG format.
As the index-based association is hard to follow and rather fragile,
rework the creation and handling of CameraStream:
1) Make the StreamConfiguration index a constructor parameter and a
private struct member. This disallows the creation of CameraStream
without a StreamConfiguration index assigned.
2) Create CameraStream only after the associated StreamConfiguration
has been identified. The first loop creates CameraStream for non-JPEG
streams, the second for the JPEG ones after having identified the
associated StreamConfiguration. Since we have just created the
CameraStream, create the JPEG encoder at the same time instead of
deferring it.
This change removes all accesses by index to the CameraDevice::streams_
vector.
No functional changes intended, but this change aims to make the code
easier to follow and more robust.
