This is a problem which we should address in TLS 1.2, but applies to 1.1.

If an app wants to be a *CLIENT* and calls:

    SSLContext.getInstance("TLSv1.1");

we're currently going to be returning an instance which won't have TLSv1.1 enabled by default.  While technically ok by the Javadoc, I think we need to change that or we're going to have some surprised developers.

Probably the easiest is extend SSLContextImpl with SSLv3, TLS1, TLSv1.1, and TLSv1.2 variants:

    public class TLSv11ContextImpl extends SSLContextImpl {

and then update SunJSSE to recognize it:

        put("SSLContext.TLSv1.1",
            "sun.security.ssl.TLSv11ContextImpl");

Then on creation of the SSLContextImpl, we enable the protocol by default.

    return new SSLSocketFactoryImpl(this,
        new String[] { "TLSv1.1", ...other suitable defaults...);
Need to integrate the update of CR 4619276 with this (to add a getDefaultProtocols/getSupportedProtocols to factories).
