"Fedora Support", step 1 ->

Several changes:
1) Make sure /bin /sbin /lib and /lib64 are ALWAYS symlinks to /usr/XXX,
   no matter what the current distribution does.
2) Make sure nobody and nogroup exist.
3) Fix various modules making assumptions that are not true on every
   distro.
4) Add symlinks to kdm module since fedora is looking for kdmrc in
   yet another spot.
5) Add detection of fedora, support its package manager

What still breaks: dnbd3
Other distros might not work now, they need adaption to changed logic
in some modules.
