Remove last vestiges of the the .mem structures.
...
Before the .array support, we had .mem nodes. These are long since
removed because the arrays to all the jobs of the .mem nodes.

Thread deletion is now scheduled after rosync.
...
Threads used to be deleted when they finished processing code.
The problem with this is that some of the code could be
rescheduled to run at rosync ($strobe, etc.). This allowed the
thread data the code depended on to be reaped too soon. This
patch uses a new queue to schedule thread deletion. The queue
is processed after rosync has finished.

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.
