    - gitlab-shell to 2.6.10 + 1 patch to remove unneeded hooks.old in *.git

      ( download speedup patches got improved, and now also properly
        proxy _gitlab_session cookie to auth backend, so raw files for
        private repositories now open in browser ok )

This only updates software and begins SR update to 8.5 - for now gitlab
instance becomes non-working -- we'll pull in configuration files
updates and fixups in the following patches.

P.S. we also pin-up rubygems version, used to build gems, along the way.
