- fix cut and paste error of comment in the oem-recovery-part-size element
  definition
  + comment is displayed in the generated doc and was misleading
- add unit test for {g,s}etAtaRaidScan method on OEMConfig class
- add unit test for {g,s}setRecoveryPartSize method on OEMConfig class
- fix bug regarding oem_recoveryPartSize
  + the value was never set as member variable thus the get method
    always returned <undef>
- fix naming inconsistency between the get and set method for the
  recovery partition size
- add value check for the recovery partition ID
  + must be a 2 digit hex value
  + also add unit test for this verification
- allow standalone building of initrd images like in older version
  * The image type 'cpio' was handled as initrd image type but
    newer versions of kiwi just use it as an archive type for the
    system image. This is a bad incompatibility and also prevents
    us from just building kiwi initrd images
- added better information about disk Volumes
- fixed partids for LVM setup:
  * The value kiwi_RootPart must always be a number, whereas
    in case of LVM we also provide kiwi_RootPartVol which takes
    the name of the root volume
- fixed missing mount and fstab entry for allfree volume
  * the volume flagged with freespace="all" was ignored in the
    mount and fstab setup code
- revert accidentally added test systemdisk section in
  suse-12.3-JeOS XML description
