RFR: 8210755: Define standard names for EC curves and TLS signature schemes

[Sean Mullan]

Please review this change to define standard names for EC curves, TLS 
signature schemes, and TLS named groups.

These names (which are Strings) are used in security APIs 
(ECGenParameterSpec) and system/security properties (jdk.tls.namedGroups 
and jdk.tls.disabledAlgorithms).

webrev: http://cr.openjdk.java.net/~mullan/webrevs/8210755/webrev.00/
CSR: https://bugs.openjdk.java.net/browse/JDK-8228752

The webrev changes just include links from the APIs to the new sections 
in the Standard Algorithm Names specification. See the CSR for details 
on the new algorithms and changes to the specification.

Thanks,
Sean
