debian/update-helper-*: packaging update helpers
* Add update-helper-control.py script to easen rename packages for new DPDK versions. - This script from libboost helps convert all package names from the old ABI name to the new one. - thanks to Jan Blunck for the conversion from boost! - the script was later updated to be python3 ready and fixing the script for all warnings/errors (but not all info) thrown by python code checkers. * Add update-helper-symbols.sh script to easen modifying the package and soname references in symbols files for new DPDK versions. - We still want to check "real" symbol delta on any update, but to make dpkg-gensymbols find the new libs the symbols files need to be updated.
