- Allow vmxboot to boot Xen EC2 instances
  In order to do that the boot device setup code now also searches
  for the presence of the 'root=...' information from cmdline as it
  is passed when booting via EC2. If found the given device is used
  and the system boots in LOCAL_BOOT mode
- KIWIImageFormat
  fixed use of qemu-img adapter_type option. If controller ist
  set to 'ide' no adapter_type needs to be specified because ide
  is the default
- Fixed grub2 prefix setup in grub.cfg. if $root is changed by a
  search it's important to update the prefix accordingly

- Fixed grub2-bios-setup call
  If the install disk is loop mounted while calling grub2-bios-setup
  the call fails the install command can't deal with disk devices
  mapped in /dev/mapper
- Added install ISO compatibility link for non standard EFI firmware
  EFI/Boot -> EFI/BOOT
- KIWIManagerZypper, allow package locks
  Using an ignore statement in the <packages> section like this

  <ignore name="some-package"/>

  did not had an effect because kiwi did not set a zypper add lock
  on the specified items. This patch now takes care for the ignore
  setup and allows to prevent the installation of packages even
  if zypper would have selected them. If a hard required package
  e.g glibc is set to become ignored this of course will cause a
  non solvable conflict and the process exits with an error
- Fixed labels configured in isolinux.msg
  The isolinux.msg is the text file displayed if no graphics theme
  could be displayed in the isolinux bootloader. In that message
  file the label "Boot from Hard Disk" was missing
