progs/gallium: Move into src/gallium/tests
Two reasons:
- progs will eventually have its own repository
- it is just to easy to forget updating the
code for interface changes when it is outside of src

+This is an application written in python to replay the traces captured by the
+ trace pipe driver.
+
+
+To use it follow the instructions in src/gallium/drivers/trace/README and
+src/gallium/state_trackers/python/README, and then do
+
+ python src/gallium/state_trackers/python/samples/retrace/interpreter.py filename.trace
+
+
+This is still work in progress:
+- not everything is captured/replayed
+ - surface/textures contents
+- any tiny error will result in a crash
