[PATCH 0/1] Add metadataCompleted Signal in Camera

[Harvey Yang]

Hi folks,

To allow partial results in Android adapter, this patch adds another
signal (along with bufferCompleted) metadataCompleted in class Camera.

Although Android allows a partial result to contain both buffers and
metadata, we probably don't need such a feature. Splitting them into
different partial results should fit both MediaTek's and Intel's
requirements.

This patch passed gitlab pipeline:
https://gitlab.freedesktop.org/chenghaoyang/libcamera/-/pipelines/1269599

Patches in Android adapter that implement partial results will follow
this one.

BR,
Harvey
