afb-api-js: first step for javascript bindingssandbox/jobol/jsapi

Adds the javascript interpreter duktape 2.3.0
for bindings written in javascript.

This is a first integration. Much more work has to be
done for fully providing an interesting feature.

The option --jsapi allows to load a file that
contains javascript. It exports its verbs using

 exports.verbname = function(req, args) ...

where req is the opaque request object and args
is the object representing arguments as returned
by afb_req_json.

The available functions are:
 - require(path) module load (ex system = require("afb:system"))
 - afb_req_success(req, result, info)
 - afb_req_fail(req, status, info)
 - result = afb_req_subcall(req, api, verb, args)
