Add parsing and translation of the FREQ form of E-source devices,
integrated with the existing parsing of AND/NAND/OR/NOR forms (inpcom.c).
For the implementation, add a new analog XSPICE code model, xfer.
Add an example to examples/sp.

When creating a plot vector from XSPICE event history, add a
final point at the end of the vector, so that a plotted line
does not end at the last event, leaving an odd spike.

Apply a patch from Aleksey Morozov to fix a bug that he identified
and reproduced. It is the same as Bug #331 -
"XSpice skips digital output point" except that it applies to the
instance queue, not the event queue.

Change output event setup in evtload.c so that, when making an event call
to a code model, there is no longer a reference to the value of the event
at the head of the free list. That allows all such free lists (with the
same data type) to be combined, probably improving performance.
This is in preparation for full implementation of inertial delay for
digital nodes.

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.
