Blue Swirl d741429a9b Add #defines needed by OpenSolaris, fix breakage by the #defines
We need to define _XOPEN_SOURCE and __EXTENSIONS__ macros in order to get
CMSG_ and TIOCWIN macros defined. But then _POSIX_C_SOURCE gets defined, which
is (incorrectly) used as an indicator for existence of posix_memalign() in osdep.c.

Anthony Liguori 4a1418e07b Unbreak large mem support by removing kqemu
kqemu introduces a number of restrictions on the i386 target.  The worst is that
it prevents large memory from working in the default build.

Furthermore, kqemu is fundamentally flawed in a number of ways.  It relies on
the TSC as a time source which will not be reliable on a multiple processor
system in userspace.  Since most modern processors are multicore, this severely
limits the utility of kqemu.

kvm is a viable alternative for people looking to accelerate qemu and has the
benefit of being supported by the upstream Linux kernel.  If someone can
implement work arounds to remove the restrictions introduced by kqemu, I'm
happy to avoid and/or revert this patch.

N.B. kqemu will still function in the 0.11 series but this patch removes it from
the 0.12 series.

Paul, please Ack or Nack this patch.

Paul Brook 88ca2a5988 Add tool_osdep.c
osdep.c is built in both as a toplevel target independant object, and
as a per-target object because of kqemu dependencies.  Under some
circumstances make picks up the wrong one.

Build the former as tool-osdep to avoid this conflict.

We want to globally define WIN_LEAN_AND_MEAN and WINVER to particular values so

Then, we can pepper in windows.h includes where using #includes that require it.

aliguori c2b48b69cb Fix -linux-user build by reverting r5701
Unfortunately, -linux-user doesn't use osdep as it replaces some of those
functions with specific ones.  The code #ifdef code in exec.c needs to
remain in place so instead of introducing a qemu_getpagesize() let's just
use getpagesize() in the non-Windows implementation of qemu_vmalloc.

aliguori 03ff3ca30f Use common objects for qemu-img and qemu-nbd
Right now, we sprinkle #if defined(QEMU_IMG) && defined(QEMU_NBD) all over the
code.  It's ugly and causes us to have to build multiple object files for
linking against qemu and the tools.

This patch introduces a new file, qemu-tool.c which contains enough for
qemu-img, qemu-nbd, and QEMU to all share the same objects.

This also required getting qemu-nbd to be a bit more Windows friendly.  I also
changed the Windows block-raw to use normal IO instead of overlapping IO since
we don't actually do AIO yet on Windows.  I changed the various #if 0's to
 #if WIN32_AIO to make it easier for someone to eventually fix AIO on Windows.

After this patch, there are no longer any #ifdef's related to qemu-img and
qemu-nbd.
