This commit mostly: * removes some (very) old messages or hacks (like those for ubuntu 10.4...). * Moves lib-specific dependencies installations to upper level (simpler to manage, and those are small enough packages). * Uses new dnf package manager for fedora (sigh, we now have tree different commands for fed/suse/rehl). * fixes or enhances some options for commandline tools. * Force anew building of oiio package, due to insane dependencies of this one in recent distro. Part of D1933.
