Start of simulation event needed to be run after initialization events.
...
This patch splits the end of compile and the start of simulation call
backs code into two different procedures. The end of compile events are
still executed at the same time they alway were. The start of simulation
events are now run after initialization.

$finish() now stops at the end of the time step not immediately.
...
The event loop used to check for $finish at every iteration. This patch
alters this behavior to only check just before you advance to the next
time step. This allows events for the current time step to complete.

Variable drivers propogate initial values.
...
Make varable drivers (reg vectors and real) propagate their initial
values using a special init scheduler queue. This causes the net to
be loaded with reasonable initial values.

Major rework of array handling. Memories are replaced with the
...
more general concept of arrays. The NetMemory and NetEMemory
classes are removed from the ivl core program, and the IVL_LPM_RAM
lpm type is removed from the ivl_target API.
