[PATCH] anaconda dekudzu-fication, final bits

[Bill Nottingham <notting redhat com>]

This set of patches adds a minimal hardware probing library to anaconda
for the loader to use, and switches to it. It would be simpler to not
have to maintain this code ourselves, but....

Notes:
- Useful descriptions for network devices are not hooked up yet
- Driver disks/manual driver selection is still broken

Tested with CD installs. Network installs seem screwy with network
config (unrelated to this - rawhide is similarly broken)
