Add support for signing and verifying XML Signatures with 2048-bit DSA keys. Also add support for the DSA-SHA256 algorithm which was added in XML Signature 1.1: http://www.w3.org/TR/xmldsig-core1/#sec-DSA JDK 8 already includes the underlying support for both of these in the Sun provider. For 2048 bit keys, the ASN.1 parsing code in the XML Signature layer needed to be adapted to handle 2048 bit keys, and for SHA-256 it was just a matter of registering the algorithm URI and instantiating a Signature object with the SHA256WithDSA algorithm.
