Change subject: utils/osmo-install-dbg-pkgs: new script
......................................................................
utils/osmo-install-dbg-pkgs: new script
Add a script that automatically figures out the debug packages for
installed Osmocom programs, libraries and their dependencies, and
installs them.
Install the script via debian/rules instead of
debian/libosmocore-utils.install, so it is possible to install to
/usr/bin/osmo-install-dbg-pkgs (without ".py" at the end).
