Alrighty, let's give this another go...

This patch hasn't changed much.  Just added bitmap_t, typedef'd to 
unsigned long * for passing around bitmaps without breaking the 
abstraction.  I think it's good if we can keep the underlying data type 
hidden to partially future-proof (protect? ;) the code.

Part 1/1 coming up...

Cheers!
