Additional certificate error types

[Chris Coulson]

We should add support for the following additional flags in OxideQSecurityStatus::CertStatus:

- net::CERT_STATUS_NON_UNIQUE_NAME (The identity of the server can't be validated because it doesn't have a FQDN).
- net::CERT_STATUS_PINNED_KEY_MISSING (The certificate doesn't match the one expected).
- net::CERT_STATUS_VALIDITY_TOO_LONG (The certificate is valid for too long - 10 years for those issued before 1/7/1012, 5 years for those after and 39 months for those after 1/4/2015)

These currently map to OxideQSecurityStatus::CertStatusGenericError.

In addition to that, we should add support for the following related errors in OxideQCertificateError::Error:

- net::ERR_CERT_NON_UNIQUE_NAME
- net::ERR_SSL_PINNED_KEY_NOT_IN_CERT_CHAIN
- net::ERR_CERT_VALIDITY_TOO_LONG

These currently map to OxideQCertificateError::ErrorGeneric.

I'm not sure how best to add these without affecting existing clients
