Use Google3 naming style to match new projects' and open source google projects' style. Preferred to do this in a massive CL so as to avoid style inconsistencies that plague legacy code bases. This is a relatively NEW code base, may as well keep it up to date. Test: name/style refactor - existing tests pass Change-Id: Ie80ecb78d46ec53efdfca2336bb57d96cbb7fb87
