win32-aio: drop win32_aio_flush_cb()

The io_flush argument to qemu_aio_set_event_notifier() has been removed
since the block layer learnt to drain requests by itself. Fix the
Windows build for win32-aio.o by updating the
qemu_aio_set_event_notifier() call and dropping win32_aio_flush_cb()....

win32-aio: Fix memory leak

The buffer is allocated for both reads and writes, and obviously it
should be freed even if an error occurs.

win32-aio: Fix how win32_aio_process_completion() frees buffer

win32_aio_submit() allocates it with qemu_blockalign(), therefore it
must be freed with qemu_vfree(), not g_free().

block: Workaround for older versions of MinGW gcc

Versions before gcc-4.6 don't support unnamed fields in initializers
(see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10676).

unnamed union. Therefore the original code does not work with older...

aio: rename AIOPool to AIOCBInfo

Now that AIOPool no longer keeps a freelist, it isn't really a "pool"
anymore. Rename it to AIOCBInfo and make it const since it no longer
needs to be modified.

raw-win32: implement native asynchronous I/O

With the new support for EventNotifiers in the AIO event loop, we
can hook a completion port to every opened file and use asynchronous
I/O on them.

Wine's support is extremely inefficient, also because it really does...
