Subject: 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.

+% function RGB=showmask(V,M,hue);
+% Input:
+%    V = image
+%    M = nonnegative mask
+%    hue = a number in [0,1], red,yellow,green,cyan,...,red
+%          a char, 'r','g','b','y','c','m'
+%          or a matrix of the same size of image
+%          eg. hue = mask1 * 0.7 + mask2 * 1;
+%   
+% Output:
+%    RGB = an RGB image with V as shades and M as saturated hues
+%    If no output is required, this image is displayed.
