Squashed commit of the sb-vbs branch.
Includes the SD-VBS benchmarks modified to:
- Use libextra to loop as realtime jobs
- Preallocate memory before starting their main computation
- Accept input via stdin instead of via argc
Does not include the SD-VBS matlab code.
Fixes libextra execution in LITMUS^RT.
