Eliminate the aio_freejobs list.  Its purpose was to store free
 aiocb's allocated by zalloc().  In other words, zfree() was never
 called.  Now, we call zfree().  Why eliminate this micro-
 optimization?  At some later point, when we multithread the AIO
 system, we would need a mutex to synchronize access to aio_freejobs,
 making its use nearly indistinguishable in cost from zalloc() and
 zfree().

Remove unnecessary fhold() and fdrop() calls from aio_qphysio(),
 undo'ing a part of revision 1.86.  The reference count on the file
 structure is already incremented by _aio_aqueue() before it calls
 aio_qphysio().  (Update the comments to document this fact.)

Remove unnecessary casts from _aio_aqueue(), aio_read(), aio_write()
 and aio_waitcomplete().

Remove an unnecessary "return;" from aio_process().

Add "static" in various places.
