Initial stab at http authentication (basic + digest) in new http stack.

General design:
- class HttpAuth -- utility class for http-auth logic.
- class HttpAuth::ChallengeTokenizer -- parsing of www-Authenticate headers.
- class HttpAuthHandler -- base class for authentication schemes (inspired by nsIHttpAuthenticator)
- class HttpAuthHandlerBasic : HttpAuthHandler -- logic for basic auth.
- class HttpAuthHandlerDigest : HttpAuthHandler -- logic for digest auth.
- The auth integration in HttpNetworkTransaction mimics that of HttpTransactionWinHttp:
  + HttpNetworkTransaction::ApplyAuth() -- set the authorization headers.
  + HttpNetworkTransaction::PopulateAuthChallenge() -- process the challenges.
