  SVN rev 184849 on 2008-11-11 14:55:59Z by ed
  
  Several cleanups related to pipe(2).
  
  - Use `fildes[2]' instead of `*fildes' to make more clear that pipe(2)
    fills an array with two descriptors.
  
  - Remove EFAULT from the manual page. Because of the current calling
    convention, pipe(2) raises a segmentation fault when an invalid
    address is passed.
  
  - Introduce kern_pipe() to make it easier for binary emulations to
    implement pipe(2).
  
  - Make Linux binary emulation use kern_pipe(), which means we don't have
    to recover td_retval after calling the FreeBSD system call.
