[Updated on 2006-9-22 again] Linux AIO module, Re: PERFORCE change 105930 for review

Updated file: linux_aio.h

Define the type "linux_aio_context_t" in the same way as genuine Linux
instead of "l_ulong".

1. Flexible on-demand linking to FreeBSD native AIO module. Only when
   linux_io_xxx() is called will native AIO module be loaded.
2. Only two symbols "aio_init_aioinfo" and "aio_aqueue" of the native
   AIO module need to be exported.

Alexander, please roll back "vfs_aio.c", and then apply my new patch
"vfs_aio.c.diff", to conform to POLA (Principle Of Least Astonishment).
And please change the value of "EXPORT_SYMS" in
"/sys/modules/aio/Makefile".
