RFR 6722928: Support SSPI as a native GSS-API provider

[Ivan Gerasimov]

Hi Max!

In sspi.cpp native memory is allocated via `new` or `new []`, and 
sometimes the returned pointer is checked for NULL.

If `new` fails, it will throw the `std:: bad_alloc` exception, so I 
believe you should use `new (std::nothrow)` and `new (std::nothrow) []` 
instead.

With kind regards,
Ivan

This code change provides a native GSS-API library inside JDK that can be used without setting the "sun.security.jgss.lib" system property. It is based on Windows SSPI and now only supports the client side using the default credentials.
