Hi all,

This series adds virtual pipeline handler, which doesn't depend on any
hardware, like camera sensor or ISP. Currently the configuration
supports test patterns and images.

It passed the gitlab pipeline:
https://gitlab.freedesktop.org/chenghaoyang/libcamera/-/pipelines/1253511
, with only merge-check warnings remaining.

Update in v9: Allocate contiguous memory for planes in the same
FrameBuffer.

BR,
Harvey
