skimage:
Add two new modes: one to write expectations to a json file, and
another to compare results against expectations.
Use SkPATH_SEPARATOR instead of '/'.

gm_expectations:
Split into a static library so it can be used by skimage.
Make functions non static and move function definitions into source
file.
Capitalize static member functions to follow the coding style
guidelines.
