jhb f3dcc2d9e0 - Add 32-bit compat system calls for VFS_AIO. The system calls live in the
aio code and are registered via the recently added SYSCALL32_*() helpers.
- Since the aio code likes to invoke fuword and suword a lot down in the
  "bowels" of system calls, add a structure holding a set of operations for
  things like storing errors, copying in the aiocb structure, storing
  status, etc.  The 32-bit system calls use a separate operations vector to
  handle fuword32 vs fuword, etc.  Also, the oldsigevent handling is now
  done by having seperate operation vectors with different aiocb copyin
  routines.
- Split out kern_foo() functions for the various AIO system calls so the
  32-bit front ends can manage things like copying in and converting
  timespec structures, etc.
- For both the native and 32-bit aio_suspend() and lio_listio() calls,
  just use copyin() to read the array of aiocb pointers instead of using
  a for loop that iterated over fuword/fuword32.  The error handling in
  the old case was incomplete (lio_listio() just ignored any aiocb's that
  it got an EFAULT trying to read rather than reporting an error), and
  possibly slower.
