This patch makes configure check zlib devel files installed.
Current configure doesn't check that, so make will fail if they
are not installed.

Replace signalfd with signal handler/pipe.  There is no way to interrupt
the CPU execution loop when a file descriptor becomes readable.  This
results in a large performance regression in sparc emulation during
bootup.
   
This patch switches us to signal handler/pipe which was originally
suggested by Ian Jackson.  The signal handler lets us interrupt the
CPU emulation loop while the write to a pipe lets us avoid the
select/signal race condition.

This adds support for running the sparse checker during the build
process.  Left it off by default for now, build becomes very noisy with
sparse checking turned on as it has to complain alot (partly even in the
system headers!).  The qemu code base needs quite some cleanups before
we should consider turning it on by default.

[..snip..]

A recent kvm merge with qemu brought code for 64bit power that broke cross
compilation. The issue is caused by configure trying to execute target
architecture binaries where configure is executed.

[..snip..]

The patch is based on Hollis's Blanchard idea.

This allows using a host's physical HCI as one of the HCIs attached
to the virtual machine.  This brings various limitations because not
all commands/events are passed through by Linux kernel, some are
interpreted by the host's kernel for a speed gain.

Be more friendly when signalfd() fails, and also add configure checks to detect
that syscall(SYS_signalfd) actually works.  malc pointed out that some installs
do not have /usr/include/linux headers that are in sync with the glibc headers
so why SYS_signalfd is defined, it's #defined to _NR_signalfd which is not
defined in the /usr/include/linux header.

While this is a distro bug, it doesn't hurt to do a more thorough job in
detection.

__GLIBC_PREREQ is defined in such a way that the ! cannot be used in front of
it on FreeBSD.  Also, -lpthread is not implied by the build and we definitely
use it for compatfd support.

While at it, I added a default initialization for posix-aio that seems to
perform well in our testing.

OpenBSD doesn't use AIO so don't try to build compatfd when not using AIO.

Also make sure to call qemu_aio_init() from bdrv_init.  Everything that uses
bdrv calls bdrv_init so it makes sense to init aio from there instead of
in every single tool.

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.

It is not enough to check for pkg-config gnutls.  You may be using a
cross-compiler and have gnutls available on the host but not for the target.
This patch changes the detection to try and build an application using gnutls
and whatever compiler is available.

Instead of having separate option for each card and driver use
--audio-drv-list and --audio-card-list options.

Under Linux it allows to set the default(first probed) driver
to something other than OSS.
