If the user specifies the backing file format,
then when opening the backing file, there is no need
to probe the (backing file) image to figure out its format.
This follows my previous patches implementing bdrv_create2
which keeps (for qcow2 only) the backing file format
as a qcow2-extension

This series is broken by design as it requires expensive IO operations at
open time causing very long delays when starting a virtual machine for the
first time.

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.

Rearrange code, help printout and docs so that they are in the same
(hopefully more logical) order for easier maintenance.
Add help and docs for undocumented options.
Reformat slightly for more consistent help output.
Add comments to encourage better synchronization in the future.

Introduce noreturn attribute and attach it to cpu_loop_exit as well as
interrupt/exception helpers for i386. This avoids a bunch of gcc4
warnings.
[ Note that this patch comes with a workaround to include qemu-common.h
even in cases where is currently causes conflicts with dyngen-exec.h.
I've been told that these conflicts will get resolved in the future
(/me will try to have a look as well - as time permits). ]

Data integrity is not important in qemu-img, so open the files with
cache=writeback. This fixes the performance regression seen with qemu-img
since revision 5485, and most particularly with the qcow2 format.
