[PATCH] Android: glretracer for Android.

[Nigel Stewart]

Regal doesn't use Waffle directly.  But I've been experimenting with
Waffle version of the Regal dreamtorus example - working nicely
for Linux and Mac - but Android...  not quite there. (build issue most
likely, on my side)

My primary interest in Waffle is for apitrace playback on Android. :-)
(Get it done! :-)
