  Added files:
    sys/i386/include     gencount.h 
  Log:
  Implement generation counters as (at least) 64 bit counters. The increment
  and get operations are interrupt safe, but not MP-safe.
  
  The gencount_inc implementation uses critical sections, which is the best
  possible for generic IA32 code.
