top: enable true line input editing with paste support

Browse Source 
This patch changes the TERMIO_PROXY define back to the
former TERMIOS_ONLY thus changing the top default too.

Plus we can now use true line input editing while also
retaining paste capability. That former native termios
support provided only a limited destructive backspace.

Now we exploit the Left/Right arrow keys, Home/End and
Delete. Plus, the Insert key can toggle overtype mode!

[ The stage is now set for a really huge improvement ]
[ to any user input terminated with the <Enter> key. ]
[ So please stay tuned for the next patch to arrive! ]

(everything is perfectly justified plus right margins)
(are completely filled, but of course it must be luck)
