Stasis events (which get distributed over the ARI WebSocket) are created by subscribing to the channel_all_cached and bridge_all_cached topics, filtering out events for channels/bridges currently subscribed to. There are two issues with that. First was a race condition, where messages in-flight to the master subscribe-to-all-things topic would get sent out, even though the events happened before the channel was put into Stasis. Secondly, as the number of channels and bridges grow in the system, the work spent filtering messages becomes excessive. Since r395954, individual channels and bridges have caching topics, and can be subscribed to individually. This patch takes advantage, so that channels and bridges are subscribed to on demand, instead of filtering the global topics. The one case where filtering is still required is handling BridgeMerge messages, which are published directly to the bridge_all topic. Other than the change to how subscriptions work, this patch mostly just moves code around. Most of the work generating JSON objects from messages was moved to .to_json handlers on the message types. The callback functions handling app subscriptions were moved from res_stasis (b/c they were global to the model) to stasis/app.c (b/c they are local to the app now).

This directory contains templates and template processing code for generating HTTP bindings for the RESTful API's. The RESTful API's are declared using [Swagger][swagger]. While Swagger provides a [code generating toolkit][swagger-codegen], it requires Java to run, which would be an unusual dependency to require for Asterisk developers. This code generator is similar, but written in Python. Templates are processed by using [pystache][pystache], which is a fairly simply Python implementation of [mustache][mustache].
