Terminal driver cleanup

[Ethan M. <merritt@u.washington.edu>]

Any objections if I update all terminal drivers in the CVS tree to
explicitly enumerate all entries in TERM_TABLE?

For example:
diff -urNP gnuplot/term/aed.trm gnuplot-enhanced/term/aed.trm
--- gnuplot/term/aed.trm        1999-06-22 04:54:13.000000000 -0700

The reason for doing this is that I would like to add a new
set of TERM_TABLE entries to support enhanced mode
text.  I've split out the driver-independent parts and moved them
to term.c. This requires driver-callbacks to do the actual=20
output.  There is no particular reason that a driver couldn't
support enhanced text without supporting MOUSE or PM3D,
and leaving the various TERM_TABLEs incompletely
specified is just asking for trouble if someone later tries to=20
implement the new call-backs at the end of an incomplete
table.
