This CL includes changes required to support multi-endpoint (see the design doc linked off the bug). Main changes include: - support for indicating if a call/connection is "external" to the device. - support for indicating if an external call can be pulled from the remote device to the local device. - API used to initiate a pull of a call external to the current device to the current device. - Made the "connection event" API public (was previously @hide); this will be used to support passing some error events involving pulling calls to the incall ui. - Added new InCallService metadata which will be used to determine if an InCallService wants to be informed of external calls. - New disconnect causes which will be used to expose the fact that a multi-endpoint call was answered elsewhere and that a call ended because it was pulled to another device. - New call log call types to indicate if calls were answered elsewhere or pulled to another device.
