Add 'afb_service_call_sync' function
This new function allows to call features for the services synchronously. Also refactoring how are handled arguments to calls. The call to 'json_object_put' is now always done by the binder. Change-Id: I910517da75b179aeafc824da4ce29bc299711990 Signed-off-by: José Bollo <jose.bollo@iot.bzh>
