These constants have internal linkage (see http://goto/totw:105 and
http://en.cppreference.com/w/cpp/language/storage_duration). Let's move them
inside HttpAuth and make them static (i.e. "class HttpAuth { public: static
const char kBasicAuthScheme[]; ...}" along with definitions in http_auth.cc.
This is consistent with how //net has historically given symbolic names to
tokens (see http_request_headers.h for example).

Moved to separate header and source files. As discussed, putting these in
HttpAuth adds unnecessary dependencies and code to libnet_nacl.
