This patch series depends on the following two series:
- "android: Exposure times + scaler crop + android metadata"

This patch series makes the following CTS tests pass:
- android.hardware.camera2.cts.StillCaptureTest#testFocalLengths
- android.hardware.camera2.cts.StillCaptureTest#testJpegExif

Mostly by filling out android result metadata and EXIF tags correctly
based on the android request metadata.

---
Changes in v5:
- fix number alignment in exif subsec tag
- improve todos
- fix static metadata size
- cosmetic and small reorganizing changes

Changes in v4:
- cosmetic and small reorganizing changes

Changes in v3:
- drop JIS and Undefined support for generating EXIF tags with undefined
  formats
- clean up exif setString
- fix endianness in exif setString
- merge setting subsec into setTimestamp (in exif)
- fix metadata entries and byte count
- move thumbnail handling to separate patch
- clean up caching request metadata
- set quality of jpeg and thumbnail

Changes in v2:
- move string encoder from utils to exif, and support no-encoding
- expand explanation about the exif orientation values
- make camera.prop file parsing nicer
- split out thumbnailer configuration and processControls into separate
  patch
- handle null request settings
