ide: device version property

Browse source 
This patch adds a new property named 'ver' to ide-drive which allows to
specify the version which the virtual disk/cdrom should report to the
guest.  By default this is the qemu version (i.e. 0.12).  usage:

  -drive if=none,id=disk,file=...
  -device ide-drive,bus=ide.0,unit=0,drive=disk,ver=42

You can also switch the version for all ide drives using:

  -global ide-drive.ver=42
