  Modified files:
    sys/sys              systm.h 
    sys/sparc64/include  param.h 
  Log:
  Move the CTASSERT macro from MD code to systm.h alongside KASSERT so other
  code can use it.  This takes a single constant argument and fails to compile
  if it is 0 (false).  The main application of this is to make assertions about
  structure sizes at compile time, in order to validate assumptions made in
  other code.  Examples:
  
  CTASSERT(sizeof(struct foo) == FOO_SIZEOF);
  CTASSERT(sizeof(struct foo) == (1 << FOO_SHIFT));
