Heads-up: Configuration language changes in new varnish version

[Ingvar Hagelund]

varnish is a high performance http accellerator.

I'm just to tag and build the new upstream version 2.1.0 of varnish.
This new version has a change in the vcl configuration language that may
need changes to existing vcl code.

If you are using varnish, please read the release notes carefully.,
