Add unit tests for odrefresh - step 1
- Define `class OnDeviceRefresh` in the header file and expose some
public methods.
- Changed the ordering of functions. (Function bodies are
not changed.)
- Move static functions to the anonymous namespace, outside of the
class.
- Cleanup "static" keywords inside the anonymous namespace.
- Move the `main` function and related functions about argument parsing
and usage help to a separate file `odrefresh_main.cc`.
- Move `Concatenate` and `QuotePath` to separate files
`odr_common.h`/`odr_common.cc`.
