  Log:
  Use the vnode v_opencount and v_writecount universally.  They were previously
  only used by specfs.  Require that VOP_OPEN and VOP_CLOSE calls match.
  Assert on boundary errors.

  Clean up umount's FORCECLOSE mode.  Adjust deadfs to allow duplicate closes
  (which can happen due to a forced unmount or revoke).

  Add vop_stdopen() and vop_stdclose() and adjust the default vnode ops to
  call them.  All VFSs except DEADFS which supply their own vop_open and
  vop_close now call vop_stdopen() and vop_stdclose() to handle v_opencount
  and v_writecount adjustments.

  Change the VOP_OPEN/fp specs.  VOP_OPEN (aka vop_stdopen) is now responsible
  for filling in the file pointer information, rather than the caller of
  VOP_OPEN.  Additionally, when supplied a file pointer, VOP_OPEN is now
  allowed to populate the file pointer with a different vnode then the one
  passed to it, which will be used later on to allow filesystems which
  synthesize different vnodes on open, for example so we can create a generic
  tty/pty pairing devices rather than scanning for an unused pty, and so we
  can create swap-backed generic anonymous file descriptors rather than having
  to use /tmp.  And for other purposes as well.

  Fix UFS's mount/remount/unmount code to make the proper VOP_OPEN and
  VOP_CLOSE calls when a filesystem is remounted read-only or read-write.
