      Refactor AIO to allow multiple AIO implementations · a76bab49
      由 aliguori 提交于 
      This patch refactors the AIO layer to allow multiple AIO implementations.  It's
only possible because of the recent signalfd() patch.  

Right now, the AIO infrastructure is pretty specific to the block raw backend.
For other block devices to implement AIO, the qemu_aio_wait function must
support registration.  This patch introduces a new function,
qemu_aio_set_fd_handler, which can be used to register a file descriptor to be
called back.  qemu_aio_wait() now polls a set of file descriptors registered
with this function until one becomes readable or writable.

This patch should allow the implementation of alternative AIO backends (via a
thread pool or linux-aio) and AIO backends in non-traditional block devices
(like NBD).

      Use signalfd() to work around signal/select race · baf35cb9
      由 aliguori 提交于 
      This patch introduces signalfd() to work around the signal/select race in
checking for AIO completions.  For platforms that don't support signalfd(), we
emulate it with threads.

There was a long discussion about this approach.  I don't believe there are any
fundamental problems with this approach and I believe eliminating the use of
signals is a good thing.

I've tested Windows and Linux using Windows and Linux guests.  I've also checked
for disk IO performance regressions.
