[Evolution] GNUTLS Support in libsoup

[Thomas F. O'Connell]

In the latest version of libsoup (1.99.28), there's a reference to
GNUTLS_CERT_CORRUPTED, which doesn't seem to exist in the latest version
of gnutls (1.0.8).

In the gnutls Changelog, the only reference to this value dates to 2002:

2002-01-29 11:52  nmav <nmav at gnutls.org>

        Added in CertificateStatus:
                GNUTLS_CERT_CORRUPTED (replaces GNUTLS_CERT_INVALID)
                GNUTLS_CERT_REVOKED

Would it make sense to reference this value only conditionally?
