baf35cb902 Use signalfd() to work around signal/select race 
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.

cd01b4a312 Fix windows build 
Right now, the Windows build is broken because of NBD.  Using a mingw32 cross
compiler is also badly broken.

This patch fixes the Windows build by stubbing out NBD support until someone
fixes it for Windows.  It also santizing the mingw32 cross compiler support
by replacing the --enable-mingw32 option with a compiler check to determine
if we're on windows or not.

Also remove the weird SDL pseudo-detection for mingw32 using a cross compiler.
The hardcoded sdl-config name is seemly arbitrary.  If you cross compiler SDL
correctly and modify your PATH variable appropriately, it will Just Work when
cross compiling.

The audio driver detection is also broken for cross compiling so you have to
specify the audio drivers explicitly for now.

902b27d0b8 Fix CVE-2008-0928 - insufficient block device address range checking 
Qemu 0.9.1 and earlier does not perform range checks for block device
read or write requests, which allows guest host users with root
privileges to access arbitrary memory and escape the virtual machine.
