78f49d5e34 android: camera_device: Fix exposure time tag in exif and android
The ExposureTime libcamera control is in microseconds while android and
our exif component use nanoseconds. Convert it appropriately.

CTS also expects the ExposureTime exif tag to match the ExposureTime set
in the android result metadata. Fix it.

1264628d3c android: jpeg: Configure thumbnailer based on request metadata
Configure the thumbnailer based on the thumbnail parameters given by the
android request metadata. Only the thumbnail encoder needs to be
configured, and since it is only used at post-processing time, move the
configuration out of the post-processor constructor and into the
processing step.

Also set the following android result metadata tags:
- ANDROID_JPEG_THUMBNAIL_SIZE
- ANDROID_JPEG_THUMBNAIL_QUALITY

abfabdd6e7 android: Set result metadata and EXIF fields based on request metadata
Set the following android result metadata:
- ANDROID_LENS_FOCAL_LENGTH
- ANDROID_LENS_APERTURE
- ANDROID_JPEG_GPS_TIMESTAMP
- ANDROID_JPEG_GPS_COORDINATES
- ANDROID_JPEG_GPS_PROCESSING_METHOD

And the following EXIF fields:
- GPSDatestamp
- GPSTimestamp
- GPSLocation
  - GPSLatitudeRef
  - GPSLatitude
  - GPSLongitudeRef
  - GPSLongitude
  - GPSAltitudeRef
  - GPSAltitude
- GPSProcessingMethod
- FocalLength
- ExposureTime
- FNumber
- ISO
- Flash
- WhiteBalance
- SubsecTime
- SubsecTimeOriginal
- SubsecTimeDigitized

Based on android request metadata.

This allows the following CTS tests to pass:
- android.hardware.camera2.cts.StillCaptureTest#testFocalLengths
- android.hardware.camera2.cts.StillCaptureTest#testJpegExif

90c193f2a7 android: Modify Encoder interface
In Encoder::encode(), the |source| argument doesn't have to be a
pointer. This replaces its type, const pointer, with const
reference as the latter is preferred to the former.
libcamera::Span is cheap to construct/copy/move. We should deal
with the type as pass-by-value parameter. Therefore this also
drops the const reference in the |destination| argument.

b2b8c4dc94 android: jpeg: Port to PostProcessor interface
Port the CameraStream's JPEG-encoding bits to PostProcessorJpeg.
This encapsulates the encoder and EXIF generation code into the
PostProcessorJpeg layer and removes these specifics related to JPEG,
from the CameraStream itself.
