TODO: Obvious Sarge amd64 mirror issues
Bump Copyright years at multiple place
Move examples from debian/examples to examples
Use dh_installexamples with a debian/examples file

This was also the reason to move the examples around in the previous
commit. :-)
Switch to a minimal dh style debian/rules

Override dh_auto_build as it triggers the nop target.
Apply wrap-and-sort to debian/control
TODO: Move /usr/lib/xen-tools/ to /usr/share/xen-tools/
Remove redundant unMountImage call
Add optional argument to unMountImage and hence runCommand to allow failure
Trap SIGINT to unmount to temporary mount point

This makes END being called again after Ctrl-C.
Normalize redundant FAIL test
It's said that just "END" is better style than "sub END".
Mention that --keep does not prevent unmounting
Fix "--extension=" with empty parameter
Add --extension option to xen-list-images
xen-list-images now also outputs the name of the config file
Make t/xen-lists-images.t more strict: No more /i
Handle Sarge amd64 case properly

Uses File::Which, (build-) dependency on libfile-which-perl added
Remove redundant and broken second setting of mirror by distribution
unMountImage may fail if $CONFIG{FAIL} is already set
