Resurrecting tooltip-use-echo-area is unrelated to making the tty version
support tooltips.  It was just a flag that re-directed the output of
tooltip-show-help to the echo area i.e. in the case of normal tooltips back to
where it was displayed before tooltips were turned on.

Normal tooltips and GUD tooltips have quite different internals and 
putting their associated code in separate files was much more modular.
Previously if tooltip-use-echo-area was set to t so that normal tooltips
displayed there, then GUD tooltips would display there.  I can
undo the alias of tooltip-use-echo-area with gud-tooltip-echo-area
and put it in tooltip.el, so that setting it to t only displays normal
tooltip there, if that would keep everyone happy.  Somehow I don't
think it will.

Note that the doc string for tooltip-use-echo-area said:

  "Use the echo area instead of tooltip frames.
This is only relevant GUD display, since otherwise it is equivalent to
turning off Tooltip mode."
