Pull out common code from client and host versions of ServerLogEntry.

This also adds unittests for ServerLogEntry client code, with common code
pulled out to a separate file.

This doesn't affect LogToServer classes - they will be refactored in a
separate CL. Also fix some IWYU issues uncovered by the refactor.

TEST=unittests
