[jdk8u-dev] RFR: 6722928: Provide a default native GSS-API library on Windows [v2]

[Alexey Bakhtin]

> Please review the backport of sspi bridge to JDK8
> 
> The backport is based on the JDK11 version and is almost clean.
> The copyright years are updated manually:
> - NativeFunc.h already has a newer copyright year
> - SunNativeProvider.java updated manually
> The main difference is a build script for sspi_bridge. It is located in SecurityLibraries.gmk
> 
> No regressions on the sun/security/krb5 tests (Windows and Linux platforms)
