This implements a framework for opting in to receiving network events asynchronously. It also converts XMLHttpRequest to use them, and paves the way for better support for synchronous XHR using on-demand, targeted event loops instead of spinning the global event loop.

The import in layout has not been changed because of a conflict with the
util mod there.
