Stefan Haberland 3f12bdf4c7 tunedasd: add copy_pair swap capability ...

Add an option to tunedasd to trigger a copy pair swap using the appropriate
ioctl for DASD devices.

      -s, --copy-pair-swap COPY_PAIR

This command requires a comma separated pair of primary,secondary to be
specified. In case of success the old secondary will become the new primary
device and the old primary will become a secondary device.

Example:

tunedasd /dev/dasda -s 0.0.9700,0.0.9740

This will set the old secondary device 0.0.9740 as the new primary.
The old primary device 0.0.9700 will automatically become a secondary
device.
