[PATCH] delete and backspace; unimplemented keys

[Manoel Rebelo Abraches]

Hello.
We have made those simple patches to fix some problems with
unimplemented keys in ieee1275 terminals.
The first patch (ofconsole_keys) implements the "backspace" and "delete"
keys.
The second one (ofconsole_unimplemented_keys) will clean the buffer of
unknown keys and prevent garbage to show up in the screen. This patch
was tested in both P5 and P6 machines.
Please review and let me know your opinion about it.
Thank you.
