Whether the paused videoState is available is dependent on the carrier's
implementation of the VT spec. The original VT implementation assumed
that this was stored in a system property accessed via InCall; these CLs
move this to a Call/Connection capability which will ultimately support
multisim video capable devices.
- Added new connection/call capabilities.
