  Added files:

  Log:
  Change the C wrappers for mmap/lseek/pread/pwrite/truncate/ftruncate to
  call the pad-less versions of the corresponding syscalls if the running
  kernel supports it.  Check kern.osreldate once per program and cache the
  result to select the appropriate syscall.  This maintains userland
  compatability with kernel.old's from quite a while back.
