2021-12-06android: Introduce PlatformFrameBufferAllocatorHirokazu Honda
The existing FrameBufferAllocator is not allowed to allocate a new buffer while Camera is running. This introduces PlatformFrameBufferAllocator. It allocates FrameBuffer using cros::CameraBufferManager on ChromeOS and gralloc on non ChromeOS platform. The allocated FrameBuffer owns the underlying buffer but must be destroyed before PlatformFrameBufferAllocator is destroyed.

2021-12-06libcamera: framebuffer: Enable attaching additional data to FrameBufferHirokazu Honda
We cannot have a subclass of FrameBuffer because it is marked as final. This adds a FrameBuffer constructor with FrameBuffer::Private. So we can attach some additional resources with FrameBuffer through a customized FrameBuffer::Private class.

2021-12-06libcamera: ipu3: Only process focus if we have a lensKieran Bingham
If there is no lens detected by the system, then we will not be able to set the control, so we can skip processing of the list. Furthermore, if the IPA has not set a V4L2_CID_FOCUS_ABSOLUTE control, then a warning will be printed as the lensControls.get() will not succeed. Break out of the control parsing when there is no CameraLens device, or if there is no absolute focus control set by the IPA.
