nit: avoid the X509Certificate forward decl and duplicate CertificateList
typedef, by including net/cert/x509_certificate.h here, rather than in the cc.

Why can only subclasses get the certificate? GetSelectedCert() is a public
method.

Do not assign default values here, use the constructor's initializer list.

[pneubeck (no reviews), 2015/02/19 20:43:49]

I wonder why, considering that this doesn't require to synchronize with the
initializer list and should thus be less error-prone. It's also style-guide
conformant.

anyways, keeping it consistent with views/ code, I guess.
Done.
