979a631ef5 Be more careful with "volatile". It still worked, but was not a good example. 
- bbl/bbl.c (REG): the cast took the volatile away

1f509de5ad Cleaned up bbl.c and added comments. 
- bbl/bbl.c: PD* macros now contain the REG(), making their use easier
- bbl/bbl.c: added description of the XBurst set/clear concept
- bbl/bbl.c: added comments all over the place

87f1ae7744 Get stdpass from kicad-libs. Added bbl.cmp to make pcbnew happy. 
- bbl.pro: use stdpass in kicad-libs, not the copy in ben-wpan (the latter
  project will use kicad-libs too)
- bbl.cmp: added to stop pcbnew from complaining each time we read the
  netlist
