Code Review Request: 8156502, Use short name of SupportedEllipticCurvesExtension.java

[Xuelei Fan]

Hi,

Please review this class name update:

    http://cr.openjdk.java.net/~xuelei/8156502/webrev.00/

The class names of SupportedEllipticCurvesExtension and
SupportedEllipticPointFormatsExtension are very long. The source codes
using the class names are likely to exceed 80 characters each line.
Better to use short names.

Thanks,
Xuelei
