  upstream patch to fix build error

- gssproxy.spec - lots of tidy up, particularly using
  pkgconfig() for BuildRequires

- Initial check-in of version 0.7.0
  gssproxy is needed on the NFS server if krb5 is used for NFS
  authentication using an AD directory server.
  /etc/krb5.conf may need "auth_to_local = RULE:[1:$1@$0]" on
  the "realms" section when "winbind" is used for nsswitch.conf.
