cc: Increased robustness of rasterize and record benchmark.

- 'protected' relevent trace events from changes, by putting argument strings
  as constants into separate file.
- fixed a bug in the collection of raster times, that would output wrong 
  statistics for layers with multiple pictures in a pile.
- Added command line parameters to set number of raster and record repeats,
  wait time before starting the benchmark, and wait time before taking the
  measurements. 
- Reduced the default number of raster and record repeats from 100 to 20. 
  This increases variance, but improves overall robustness (e.g. avoiding
  event buffer overflows)
- Added command line option to print statistics after every page run.
