  Log:
  Put on my peril sensitive sunglasses and add a flags field to the internal
  sysctl routines and state.  Add some code to use it for signalling the need
  to downconvert a data structure to 32 bits on a 64 bit OS when requested by
  a 32 bit app.
  
  I tried to do this in a generic abi wrapper that intercepted the sysctl
  oid's, or looked up the format string etc, but it was a real can of worms
  that turned into a fragile mess before I even got it partially working.
  
  With this, we can now run 'sysctl -a' on a 32 bit sysctl binary and have
  it not abort.  Things like netstat, ps, etc have a long way to go.
  
  This also fixes a bug in the kern.ps_strings and kern.usrstack hacks.
  These do matter very much because they are used by libc_r and other things.
