  Log:
  Profiling cleanup.
  
  This commit eliminates some duplication in the various heap profiling
  subsystems, and generally centralises much of the machinery.  The key
  concept is the separation of a heap *census* (which is now done in one
  place only instead of three) from the calculation of retainer sets.
  Previously the retainer profiling code also did a heap census on the
  fly, and lag-drag-void profiling had its own census machinery.
  
  Value-adds:
  
     - you can now restrict a heap profile to certain retainer sets,
       but still display by cost centre (or type, or closure or
       whatever).
  
     - I've added an option to restrict the maximum retainer set size
       (+RTS -R<size>, defaulting to 8).
  
     - I've cleaned up the heap profiling options at the request of
       Simon PJ.  See the help text for details.  The new scheme
       is backwards compatible with the old.
  
     - I've removed some odd bits of LDV or retainer profiling-specific
       code from various parts of the system.
  
     - the time taken doing heap censuses (and retainer set calculation)
       is now accurately reported by the RTS when you say +RTS -Sstderr.
  
  Still to come:
  
     - restricting a profile to a particular biography
       (lag/drag/void/use).  This requires keeping old heap censuses
       around, but the infrastructure is now in place to do this.
