Generates the DTLS identity in browser process and returns it to the renderer process.

This is the first part of implementing a persistent identity store for WebRTC in Chrome. It implements the IPC messages to request and return the DTLS identity and the identity generation in browser process. A persistent store based on SQLite DB will be implemented later.

DTLSIdentityService: used in the renderer process to request a DTLS identity. It sends an IPC to the browser process and receives the reply containing the identity in a callback.
DTLSIdentityServiceHost: listens for the IPC message from DTLSIdentityService and passes the request to DTLSIdentityStore.
DTLSIdentityStore: created per RenerProcessHost. For now it always generates a new identity on a worker thread for each request, without any caching or persistent storage.
