xmlsecurity: improve handling of multiple X509Data elements
Combine everything related to a certificate in a new struct X509Data.
The CertDigest is not actually written in the X509Data element but in
xades:Cert, so try to find the matching entry in
XSecController::setX509CertDigest().
There was a confusing interaction with PGP signatures, where ouGpgKeyID
was used for import, but export wrote the value from ouCertDigest
instead - this needed fixing.
The main point of this is enforcing a constraint from xmldsig-core 4.5.4:
All certificates appearing in an X509Data element MUST relate to the
validation key by either containing it or being part of a certification
chain that terminates in a certificate containing the validation key.
