Issue: Workflow issue in BTIF driver.

Capture: Working
Issue: User handle is required in GetMemory. MTK blobs return null.
Patch: Save a copy of the user handle. Don't know if other devices might work or not. It's better to rebuild a few blobs but I don't have the source for my device…
Issue: Oreo use a ring buffer of native_handles and no more ANativeWindowBuffer.
Patch: A wrapper is required for the libcam.client. (The better way would be rebuild it but again no source…)
HDR: Working with Snap in LOS-15.1
Video recording: Working
Issue: Oreo doesn't support GRALLOC (or I don't know how). The old HAL1 implementation doesn't work too.
In short, need to find a way for the metadata that our old blobs can handled.
Patch:
1. Add libcamera_parameters_mtk for the MTK extra parameters
2. Add another mode to handle Gralloc in stragefright.
3. Patch the OMXNode to handle Gralloc mode.
4. patch the OMXClient to use mediaserver
5. Patch the hardware interface to handle Gralloc Metadata and work with the new OMX interface.

2. Wrap (eventually replaced) the libril from MTK with AOSP patching for MTK
3. Patch the RIL interface/service to work with the MTK vendor library.
