Hi,

I rebased the patch series to add fsfreeze for Windows qemu-ga.

changes from v9:
  - Fix conflict with commit e8ef31a3518c "qemu-ga: build it even if !system"

changes from v8:
 - Add hEventTimeout to improve timeout error message (patch 07, see below)
 - Build qga-vss.tlb if configure'd --with-win-sdk (patch 05, 07)
 - Use "qga-vss-dll-obj-$(CONFIG_QGA_VSS)" in Makefile.objs (patch 07)
 - Fix typo in QGAVSSRequesterFunc (patch 07, 08)

v9: http://lists.nongnu.org/archive/html/qemu-devel/2013-07/msg06071.html

* Description
  In Windows, VSS (Volume Shadow Copy Service) provides a facility to
  quiesce filesystems and applications before disk snapshots are taken.
  This patch series implements "fsfreeze" command of qemu-ga using VSS.


* How to build & run qemu-ga with VSS support

 - Download Microsoft VSS SDK from:
   http://www.microsoft.com/en-us/download/details.aspx?id=23490

 - Setup the SDK
   scripts/extract-vsssdk-headers setup.exe (on POSIX-systems)

 - Specify installed SDK directory to configure option as:
   ./configure --cross-prefix=i686-w64-mingw32- \
               --with-vss-sdk="path/to/VSS SDK" \
               --without-systems --without-tools

 - make qemu-ga.exe qga/vss-win32/qga-vss.{dll,tlb}

 - Install qemu-ga.exe, qga/vss-win32/qga-vss.{dll,tlb}, and
   the other required mingw libraries into the same directory in guests

 - Run `qemu-ga.exe -s install' and `net start qemu-ga' in the guests

Any feedback are appreciated.
