in the runtime.

Allow VPI callbacks to var array words.
...
Functions like $monitor need to attach callbacks to array words if
those words are to be monitored. Have the array hold all the callbacks
for words in the array, under the assumption that the monitored words
are sparse.

Remove last vestiges of the the .mem structures.

removed because the arrays to all the jobs of the .mem nodes.

At EOS only save the simulation time if it is asked for.
...
This was causing a core dump for a number of the vpi test cases.
The problem was that they did not need the simulation time, so it
was being set to NULL. The problem was the EndOfSimulation callback
was always setting cb_data.time to the current time. A big problem
when the pointer was NULL. The solution is to only set the time
when the pointer is not NULL

Add a mark at simulation end for vcd/lxt/lxt2 files.
...
This patch adds marks at simulation end if needed and enabled (on
and not over the limit) for vcd/lxt/lxt2 files. End of simulation
callbacks also now have the correct simulation time. The default
file names for lxt and lxt2 now match the vcd file except for the
extension. lx2 is also an alias for lxt2 and the default lxt2 file
extension is lx2. This matches what GTKWave expects. Any lxt2
diagnostic output print LXT2 instead of LXT to make it clear which
dumper you are using.

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.

Make vpi_put_value to a real accept an integer value and add diagnostic code.
...
Modified the code that deals with real variables to accept an integer
value when using vpi_put_value(). Also added some type of diagnostic
message for all switch defaults that have an assert(0) to indicate an
error condition, removed CVS comments and removed a small section of
unreachable code.

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.
