Summary: Clean up the include guards to be more consistent and unique. Some files used include guards like "KEY_H" and "STORE_H" which were not very unique, and are more likely to collide with definitions provided by header files from other projects. Some of the py-*.h files were missing include guards altogether. This corresponds to Facebook diff D5588670. Test Plan: Confirmed the code still builds and passes tests.
