- Change the way we create an EC2 image
  + Previously we created an EC2 image as a flat filesystem image
    this requred some special codeing and we ended up calling mkinitrd
    from within kiwi. As mkinitrd evolved to require a live root filesystem
    and with the impending move to dracut we need to start using a kiwi
    generated initrd. Therefore, EC2 image will now be created as disk
    images just like other vmx images. We also drop the use of the
    external ec2-ami-tools. Creating abundle is relatively easy and this
    functionality requires people to add thei EC2 credentials to the config
    file. That makes it easy to accidentally share private information.
  + Remove XML elemnts ec2config and its children
    ec2accountnr, ec2certfile, ec2privatekeyfile, ec2region
  + Introduce "ec2" as a firmware option
    we need this to set the partition table to be gpt instead of msdos
  + Print an error message for format="ec2" during XML validation
    we maintain format="ec2" in the schema for now to allow us to generate
    a more sensible error message than the parser would. This is an
    incompatible schema change
  + Remove EC2 region check in Validator
  + Remove KIWIEC2Region.txt
  + Update unit tests
  + Properly pass the boottimeout setting to the initrd config
  + Remove the XMLEC2Data object and its unit tests
  + Remove special code for EC2 initrd creation calling mkinitrd

- added ec2Flavour profile to create EC2 VMX disk image types along
  with this change the examples using format="ec2" were adapted to
  disk layout instead of flat (filesystem) layout too

- Fixed ec2 kernel profile for 13.1 and SLE11
  the required xen drivers were not added when using ec2 profile
  the xen package must not be installed when using ec2 profile

- Update oem/vmx boot image descriptions to allow selecting
  an ec2 setup profile and an ec2 kernel profile

- Fixed vmx type definition for EC2 usage in all templates
  * use ec2 and ec2k boot and kernel profiles

- fix spelling EC2 not Ec2

- update the documentation for the EC2 image build
  + document new commands to use for uploading images aws-cli vs ec2-*
    commands
  + changes due to the new way of building images
    - we no longer create the bundle in kiwi
    _ adjust for removed XML elements
- update the examples to reflect the new type element setup for EC2

- final touches for EC2 changes
  + let kiwi add root= to the kernel command line for EC2 images
    this is needed to get the drivers to load properly
  + consider installfailsafe setting for grub vmx images

- Fixed docbook syntax for changes recently done in kiwi-doc-ec2.xml

- ec2 example for 13.1
  + forgot to commit this with the doc changes in 87b49253440eda

- 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
- v5.05.49 released
