Matt Jacob 57c801f5cf A wad of changes- prepping for 1080/1240 support (which caused a massive 
thwank in register layout goop). A different mboxcmd approach. Some PDB change
infrastructure. Some better management of loopdown/loopup events (keep them
distinct from resource starvation for simq freeze/unfreeze actions).
