  Log:
  SVN rev 220456 on 2011-04-08 18:48:57Z by attilio
  
  Reintroduce the fix already discussed in r216805 (please check its history
  for a detailed explanation of the problems).
  
  The only difference with the previous fix is in Solution2:
  CPUBLOCK is no longer set when exiting from callout_reset_*() functions,
  which avoid the deadlock (leading to r217161).
  There is no need to CPUBLOCK there because the running-and-migrating
  assumption is strong enough to avoid problems there.
  Furthermore add a better !SMP compliancy (leading to shrinked code and
  structures) and facility macros/functions.
  
  Tested by:      gianni, pho, dim
  MFC after:      3 weeks
