  Log:
  Remove Giant from CAM.  Drivers (SIMs) now register a mutex that CAM will
  use to synchornize and protect all data objects that are used for that
  SIM.  Drivers that are not yet MPSAFE register Giant and operate as
  usual.  RIght now, no drivers are MPSAFE, though a few will be changed
  in the coming week as this work settles down.
  
  The driver API has changed, so all CAM drivers will need to be recompiled.
  The userland API has not changed, so tools like camcontrol do not need to
  be recompiled.
