Getting rid of SPARSE for Initial Circuit Matrix creation. Now KLU is totally independent from SPARSE. This opens up the interface for other solvers as well
SPARSE can still used through '.options sparse', but it isn't possible to switch from KLU to SPARSE and viceversa at run-time

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.
