2020-10-07libcamera: ProcessManager: make ProcessManager lifetime explicitly managedPaul Elder
If any Process instances are destroyed after the ProcessManager is destroyed, then a segfault will occur. Fix this by making the lifetime of the ProcessManager explicit, and make the CameraManager construct and deconstruct (automatically, via a member variable) the ProcessManager. Update the tests accordingly.

When requesting one RAW stream and one YUV stream the StreamConfiguration assigned to the RAW stream is the first one added to the CameraConfiguration, while the YUV stream gets assigned to the main output. At configure() time the viewfinder output needs to be configured with the same format as the main output, but since the introduction of RAW capture support, the pipeline has not been updated and still assumes the main output configuration is the first one in the CameraConfiguration. This causes the viewfinder to be configured with the same format as the raw stream, breaking capture operations.

This commit plumbs the user transform from the Raspberry Pi pipeline handler through to the IPA.

Once in the IPA we add it to the CameraMode description, so that it becomes automatically available to all the individual control algorithms.

Note that the validate() method has to work out what the final Bayer order of any raw streams will be, before configure() actually applies the transform to the sensor.
