Subject: [PATCH 04/14] Add JWT middleware validation failure log (#760)

We will log the middleware log now, but in the next
releases we should provide a generic error that can be
parsed by the dashboard.

Subject: [PATCH 05/14] Add custom ice stdnet implementation (#754)

On Android, because of the hard SELinux policies can not list the
interfaces of the ICE package. Without it can not generate a host type
candidate. In this pull request, the list of interfaces comes via the Java
interface.
