[Db] [XmlRpc] Use of undefined classes

[marc-mabe]

As noted in #3496 there some uses of undefined classes:

• Zend\Db\Metadata\Source\AbstractSource uses the not existing class Object\ConstraintKeyObject
• Zend\XmlRpc\Server\Exception\Stdin::____construct() uses new ServerException which is defined as use Zend\XmlRpc\Server\Exception as ServerException but that's a namespace and not a exception class
• Zend\XmlRpc\AbstractValue::_phpVarToNativeXmlRpc checks against Zend\Math\BigInteger

Last two points looks easy to fix.

I'll have a look at that this week, it likely should use it, but I am uncertain. The majority of the work for Metadata source came in from a contributor, so let me get up to speed first.
