Initial rewrite for varnish 5.2
* src/betab.c (backend_dfn): Change type of the vpt array. All uses updated. (backend_clear): No need to release vpt entries now. * src/varnish_mib.mib2c (VarnishMib::MIBTable): Change data table to keep entries of const volatile uint64_t *. (varnish_var_lookup, varnish_get_oid, dict_install): Reflect that change. (vd): Rename to vsm. (dict_load): Change arguments to VSC_Iter (post_config): VSC_New takes no arguments.
