Most browsers no longer trust 1024bit certificates, or certificates signed by them, instead verifying them by a trusted intermediate or a cross-sign from another trusted certificate.
Unfortunately, as it turns out, OpenSSL prior to 1.0.1g cannot correctly handle certificates chains such as this, even if one of the intermediates is trusted.
The solution is that we need to continue to trust the 1024bit legacy root certificates forthe foreseeable future
This adds the following certificates back into our trust store:
{{{
GTE CyberTrust Global Root
Thawte Server CA
Thawte Premium Server CA
Verisign Class 3 Public Primary Certification Authority
Verisign Class 3 Public Primary Certification Authority - G2
ValiCert Class 1 VA
ValiCert Class 2 VA
RSA Root Certificate 1
Entrust.net Secure Server CA
Equifax Secure Global eBusiness CA
Equifax Secure eBusiness CA 1
America Online Root Certification Authority 1
America Online Root Certification Authority 2
NetLock Business (Class B) Root
NetLock Express (Class C) Root
Verisign Class 3 Public Primary Certification Authority
}}}

This changeset also bundles ca-bundle.crt from the Mozilla project to allow for us to verify SSL certificates on hosts which have an incomplete, outdated, or invalid local SSL configuration.
Props rmccue for major assistance getting this this far. See #25007 for discussion, also Fixes#16606
