If we receive an HTTP authentication header with a non-ASCII realm string, the ASCIIToWide call in PopulateAuthChallenge hits a DCHECK failure.  Change the ASCIIToWide call to a base::SysNativeMBToWide call, which produces the correct result when the OS "language for non-Unicode programs" is set to the language of the realm string.
