  SVN rev 182760 on 2008-09-04 15:15:39Z by jkim
  
  MFC: Sync. BPF JIT compiler with HEAD.
  
  - r182172:
  Embed scratch memory in the filter structure.
  
  - r182173:
  Fix a typo in copyrights.
  
  - r182220:
  Move empty filter handling to MI source.
  
  - r182376:
  Initialize scratch memory for JIT-compiled filter when it is allocated.
  Previously it may have contained unnecessary (even sensitive) data from
  the previous allocation.
  As a (good) side effect, scratch memory may be used to store the previous
  filter state(s) safely because it is allocated and freed with filter itself.
  However, use it carefully because bpf_filter(9) does not have this behavior.
