Move Origin to its own header so that SkPixmap and SkJpegEncoder need not depend on SkCodec. Add libexif, which is already used by Android, and use it to write the orientation. Write a makefile based on the Android.bp in Android, minus warnings. (libexif has an LGPL license.) Add a test that verifies all the orientations work. Optionally enable writing the orientation (and therefore including libexif). Chromium does not currently need it, and Android does not expose an API that would allow using it. Disable on Windows, where we still have build errors to fix.
