Fix crash in XServerPixelBuffer.

XServerPixelBuffer contains x_image_ field, that may be allocated using
XGetImage() or XShmCreateImage() depending how the last frame was captured.
x_image_ is passed XShmGetImage(), which may crash if it gets image
allocated with XGetImage(). Added x_shm_image_ to ensure that SHM and
non-SHM capture paths are separate and XShmGetImage() is allways called
with the correct XImage.

The linked bug appears to be a regressiona after

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.
