xmlsecurity: replace OOXMLSecParser implementation
This is similar to 12b15be8f4f930a04d8056b9219ac969b42a9784 and following
commits, but OOXMLSecParser has some differences to XSecParser, such as
using a ds:Manifest, and requires a couple extra namespaces.

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.

xmlsecurity: improve handling of multiple certificates per X509Data
It turns out that an X509Data element can contain an arbitrary number of
each of its child elements.
How exactly certificates of an issuer chain may or should be distributed
across multiple X509Data elements isn't terribly obvious.
One thing that is clear is that any element that refers to or contains
one particular certificate has to be a child of the same X509Data
element, although in no particular order, so try to match the 2 such
elements that the parser supports in XSecController::setX509Data().
Presumably the only way it makes sense to have multiple signing
certificates is if they all contain the same key but are signed by
different CAs. This case isn't handled currently; CheckX509Data() will
complain there's not a single chain and validation of the certificates
will fail.

xmlsecurity: avoid exception in DigitalSignaturesDialog::getCertificate()
Fallback to PGP if there's no X509 signing certificate because
CheckX509Data() failed prevents the dialog from popping up.
To avoid confusing the user in this situation, the dialog should
show no certificate, which is already the case.
