[PATCH] Android: glretracer for Android.

[Nigel Stewart]

Concerning Android tree versus NDK.  I see apitrace as very user-space
oriented, what I was considering for Regal was to build a
non-functional waffle .so for linking, and assume that the real waffle
is already installed on the device.  Does that same assumption make
sense for apitrace also?
