Add remoting plugin for output streaming

Remoting plugin support streaming image of virtual output on drm-backend
to remote output. By appending remote-output section in weston.ini,
weston loads remoting plugin module and creates virtual outputs via
remoting plugin. The mode, host, and port properties are configurable in
remote-output section.

This plugin send motion jpeg images to client via RTP using gstreamer.
Client can receive by using following pipeline of gst-launch.

gst-launch-1.0 rtpbin name=rtpbin \
   udpsrc caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,
		encoding-name=JPEG,payload=26" port=[PORTNUMBER] !
          rtpbin.recv_rtp_sink_0 \
   rtpbin. ! rtpjpegdepay ! jpegdec ! autovideosink \
   udpsrc port=[PORTNUMBER+1] ! rtpbin.recv_rtcp_sink_0 \
   rtpbin.send_rtcp_src_0 !
          udpsink port=[PORTNUMBER+2] sync=false async=false

where, PORTNUMBER is specified in weston.ini.
