Single Peer Connection for Chrome

This release adds preliminary support for publishing and subscribing streams in the same Peer Connection, which reduces CPU and publishing and subscribing delays.

We have been also working on improving Simulcast by adding new APIs to activate slideshow when the estimated bandwidth is low and to have high quality recordings with simulcast.

We have also fixed several bugs and some known issues that were causing crashes in the MCU.
