GNUtify TUI code, enable TUI

[Andrew Cagney]

Hello,

I think its time to GNUtify the TUI code.  Actually, the code should 
have been GNUtifyed before that faitful first commit, however now is 
better late than never :-)  (Stephane's been careful to ensure that any 
new code is GNUtiful, this will fix the old code).  As for building 
theTUI by default, its been on the things-to-do-today list for too long 
:-(  So the plan is:

~2004-01-10: Rename the files/functions.  Mindless, tedious, but 
relatively "obvious".

~2004-01-17: Enable the TUI by default.
