2021-10-26android: post_processor: Consolidate contextual informationUmang Jain
Save and provide the context for post-processor of a camera stream via Camera3RequestDescriptor::StreamBuffer. We extend the structure to include source and destination buffers for the post processor, along with CameraStream::Type::Internal buffer pointer (if any). In addition to that, a back pointer to Camera3RequestDescriptor is convenient to get access to overall descriptor (status, metadata settings etc.). Also, migrate CameraStream::process() and PostProcessor::process() signature to use Camera3RequestDescriptor::StreamBuffer only. This will be helpful when we move to async post-processing in subsequent commits.

2021-10-19android: camera_stream: Plumb process() with Camera3RequestDescriptorUmang Jain
Data (or broader context) required for post processing of a camera request is saved via Camera3RequestDescriptor. Instead of passing individual arguments to CameraStream::process(), pass the Camera3RequestDescriptor pointer to it. All the arguments necessary to run the post-processor can be accessed from the descriptor.

2021-03-03android: post_processor: Use CameraBuffer APIJacopo Mondi
Use the newly introduced CameraBuffer class as the type for the destination buffer in the PostProcessor class hierarchy in place of the libcamera::MappedFrameBuffer one and use its API to retrieve the length and the location of the CameraBuffer plane allocated for JPEG post-processing. Remove all the assumption on the underlying memory storage and only go through the CameraBuffer API when dealing with memory buffers. To do so rework the Encoder interface to use a raw pointer and an explicit size to remove access to the Span<uint8_t> maps that serve as memory storage for the current implementation but might not be ideal for other memory backend. Now that the whole PostProcessor hierarchy has been converted to use the CameraBuffer API remove libcamera::MappedBuffer as base class of the CameraBuffer interface and only reply on its interface.
