BUG/MINOR: dns: check and link servers' resolvers right after config parsing

On the Mailing list, Marcos Moreno reported that haproxy configuration
validation (through "haproxy -c cfgfile") does not detect when a
resolvers section does not exist for a server.
That said, this checking is done after HAProxy has started up.

The problem is that this can create production issue, since init
script can't detect the problem before starting / reloading HAProxy.

To fix this issue, this patch registers the function which validates DNS
configuration validity and run it right after configuration parsing is
finished (through cfg_register_postparser()).
Thanks to it, now "haproxy -c cfgfile" will fail when a server
points to a non-existing resolvers section (or any other validation made
by the function above).
