fix up local_nvra and fix for a missing localinstall rpm file.

Add working CPU model fact for some ARM devices

Check for terminal capabilities if curses is available

This takes started, stopped and restarted.

Started returns when connecting is possible.
Stopped when connecting is not possible.
Restarted first waits for connecting to be impossible and returns when it is
possible again.
