Add an Option for orientation on JPEG encodes
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.
