theoradec: add properties to enable debugging telemetry overlay

Browse source 
The theora decoder can overlay debugging information on the output
video. This functionality is only available if libtheora has been
compiled with --enable-telemetry. For more details see:

http://people.xiph.org/~xiphmont/demo/theora/demo2.html

Based on original patch by Michael Smith <msmith at xiph org>
