commit 43ca78b29ea7366bbbc35e28a272fb145771181f
Author: wangjimmy <wangjimmy@chromium.org>

Add interface versioning for javascript.

Methods queryVersion and requireVersion are added to InterfacePtrController.
Support sending and handling control messages by creating control_message_proxy
and control_message_handler. control_message_proxy uses promises as opposed to
callbacks which is what our original cpp code does.
