Bug 927954 - Adding rendertrace logging to the APZ code. r=botond

Browse Source 
To use this logging, enable the #define at the top of
AsyncPanZoomController.cpp, run through the scenario you wish
to trace and collect the logs, and then paste them into the
textarea on the page at github.com/staktrace/rendertrace/.
