Support VPN adapter type in WebRTC Android.

The VPN adapter type is not effectively supported in WebRTC Android for
1) the network monitor may not obtain the VPN adapter type from the OS,
e.g. via NetworkInfo.getType, 2) and VPN adapter type is replaced
by the adapter type of an underlying network by the network monitor in
the current implementation. Specifically, WebRTC Android would
previously classify VPNs as either type ADAPTER_TYPE_UNKNOWN, or the
type of the currently active network (which we assume the VPN is
using).

In this CL, VPNs are classified as ADAPTER_TYPE_VPN whenever possible,
and the underlying network type, if available from the VPN, is
separately stored and used to prioritize ICE candidates in network path
selection.

This allows ADAPTER_TYPE_VPN to be used in networkIgnoreMask to ignore
VPNs when gathering ICE candidates.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development

See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.
