Fix warning in vl.c

vl.c calls dma_helper_init, so it needs to include dma.h to get a
definition for it, otherwise we get compiler warnings like:

/home/hch/work/qemu/vl.c: In function 'main':
/home/hch/work/qemu/vl.c:5518: warning: implicit declaration of function 'dma_helper_init'...

Implement cancellation method for dma async I/O (Avi Kivity)

Move the dma helpers to a private aio pool, and implement a cancellation

DisplayAllocator interface (Stefano Stabellini)

Hi all,
this patch adds a DisplayAllocator interface that allows display

for the graphical backend to use.

Fix windows build and clean up use of <windows.h>

We want to globally define WIN_LEAN_AND_MEAN and WINVER to particular values so
let's do it in OS_CFLAGS.

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