Certain paths through vpi_put_value cause a vpip_put_value_event to
be created with no path for deleting in. Add the capability in the
schedule_generic method, so that it can be delete as soon as it is
executed.
The schedule_assign_plucked_vector is a better way to implement the
schedule_assign_vector, or at least no worse, so remove the now
redundent schedule_assign_vector.
The vvp_net_t objects are never deleted, so overload the new operator
to do a more space efficient permanent allocation.
The %assign/v instruction copied the vvp_vector4_t object needlessly
on its way to the scheduler. Eliminate that duplication.(cherry picked from commit d0f303463d)
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.
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.

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.
