Code Review Request 8049321 Support SHA256WithDSA in JSSE

[Xuelei Fan]

Hi,

Please this enhancement to the JSSE implementation:

   http://cr.openjdk.java.net/~xuelei/8049321/webrev.00/

This change will add support for the SHA224withDSA and SHA256withDSA
algorithms in the TLS "signature_algorithms" extension in the SunJSSE
provider.  Note that this extension does not apply to TLS 1.1 and
previous versions.

Thanks,
Xuelei
