The EventEmitter API we inherited from Node.js and then bastardized was getting awkward and cumbersome. The number of uses of ve.bind was getting out of control, and removing events meant caching the bound method in a property. Many of the "features" of EventEmitter wasn't even being used, some causing overhead, others just causing bloat. This change cleans up how EventEmitter is used throughout the codebase. The new event emitter API includes: * emit - identical to the previous API, no longer throws an error if you emit error without a handler * once - identical to the previous API, still introduces a wrapper* on - compatible with the previous API but has some new features * off - identical to removeListener in the previous API * connect - very similar to addListenerMethods but doesn't wrap callbacks in closures anymore * disconnect - new, basically the opposite of addListenerMethods Another change that is made in this commit is mixing in rather than inheriting from EventEmitter. Finally, there are changes throughout the codebase anywhere connect/disconnect could be used. Change-Id: Ic3085d39172a8a719ce7f036690f673e59848d3a
