Patch fixing this bug and adding support for specification of a validation time

The proposed patch would fix this bug.

The Qt5 interface in qt5/src/poppler-form.h gets the following new methods:
QString signerSubjectDN() const;
QString getHashAlgorithmName() const;
const QByteArray& getSignature() const;
QList<qint64> signedRangeBounds() const;
bool signsTotalDocument() const;

Moreover, the interface of method validate in qt5/src/poppler-form.h is
extended 
to take an optional validation time:
SignatureValidationInfo validate(int opt, const QDateTime& validationTime =
QDateTime()) const;

The binary pdfsig with this patch also tells the full Distinguished Name of the
signer and the Hash Algorithm used for signing.</pre>
