Extend the output and partial derivatives of the output from the 2/3-D
table lookup models (XSPICE) continuously outside the defined
rectangle or cube, as it may help convergence and avoid ambiguity caused
by rounding at the boundaries. See bug #591 "Wrong 2D table model output".
The value is that of the nearest point in the region while the reported
derivative is ramped to zero outside the boundaries.
Also fixes incorrect output at the upper limit in each dimension.

The AD and DA hybrid XSPICE bridges consume a lot of
memory (one state per time step added). Memory of
previous time steps is not recovered.

dramatically (> factor of 10).
