linux-kernel and linux kernel modules ABI tools.

linux-kernel and linux kernel modules ABI tools.

The following changes have been implemented:
    1. A new tool "abi-checker" has been created. The tool allows:
       - compare two Module.symvers files.
       - reports which symbols are new, changed or have been removed.
       - create dump all kernel symbols that are present in external kernel
         module.

    2. linux-3.10.spec has been updated to check changes in kernel ABI/API.
       In case if any change kernel installation process aborts. In such case
       user is requested to update kernel version and update ABI dump file.
       ABI dump file should be located in "abi-checker/data" directory.

    3. Output rpm with uImage has been extended by ABI dump. Default location for
       the file is /boot/abi/_kernel_version_.

    4. New output rpm package is build - "abi-tools". The package delivers ABI-checker.
       By default the rpm install ABI-checker tool into /usr/local/bin directory.
