please rename those to WebConntectionType.* (separate CL is ok)

Done. https://codereview.chromium.org/1333613004

net info helper will crash with this (at least until you've updated it), no? can
we avoid that?

The browser side doesn't use wimax yet, and the conversion only goes one way
(browser to renderer).

     ConnectionTypeOther,
     ConnectionTypeNone,
     ConnectionTypeUnknown,
     ConnectionTypeLast = ConnectionTypeUnknown
 };
 
 } // namespace blink
 
 #endif // WebConnectionType_h
