Add a new extensible GSS-API layer which can support GSS-API plugins,
similar the the Solaris implementation. Repackage the krb5 GSS mechanism as a plugin library for the new implementation. This also includes a comprehensive set of manpages for the GSS-API functions with text mostly taken from the RFC. Reviewed by: Love Hörnquist Åstrand <lha@it.su.se>, ru (build system), des (openssh parts)
