Ivailo Monev 9585bd773c mark certain core component options unsupported 
this is mostly automated change set, a lot to be done later on
especially about the definitions in core component. the goal is
to make most of the options of the core component available so
that they can be utilized in other components and tools without
restrictions as shown by some of the changes done to the GUI
component in this commit

\class QSslCertificate
\brief The QSslCertificate class provides a convenient API for an X509 certificate.
\since 4.3
\reentrant
\ingroup network
\ingroup ssl
\inmodule QtNetwork
QSslCertificate stores an X509 certificate, and is commonly used
to verify the identity and store information about the local host,
a remotely connected peer, or a trusted third party Certificate
Authority.
There are many ways to construct a QSslCertificate. The most
common way is to call QSslSocket::peerCertificate(), which returns
a QSslCertificate object, or QSslSocket::peerCertificateChain(),
which returns a list of them. You can also load certificates from
a DER (binary) or PEM (Base64) encoded bundle, typically stored as
one or more local files, or in a Qt Resource.
You can call isNull() to check if your certificate is null. By
default, QSslCertificate constructs a null certificate. To check
if the certificate is valid, call isValid(). A null certificate is
invalid, but an invalid certificate is not necessarily null. If
you want to reset all contents in a certificate, call clear().
After loading a certificate, you can find information about the
certificate, its subject, and its issuer, by calling one of the
many accessor functions, including version(), serialNumber(),
issuerInfo() and subjectInfo(). You can call effectiveDate() and
expiryDate() to check when the certificate starts being
effective and when it expires.
The publicKey() function returns the certificate
subject's public key as a QSslKey. You can call issuerInfo() or
subjectInfo() to get detailed information about the certificate
issuer and its subject.
Internally, QSslCertificate is stored as an X509 structure. You
can access this handle by calling handle(), but the results are
likely to not be portable.
