Conditionally use OPUS_GET_IN_DTX if available

OPUS_GET_IN_DTX was added 2019-04-15, but we still need to support
building on systems with older versions of the Opus headers (eg. Debian
Jessie, released 2015-04-25).  This is needed to fix the "Build From
Tarball" bot [1].

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.

Authoritative list of directories that contain the native API header files.
