Scheduler cells are small objects that come and go in great quantities.
Even though they are allocated and deallocated a lot, they tend to a
steady state quantity, so put together a heap that is unique for each
cell type.
This heap actually saves memory overall because cells are allocated in
chunks, thus eliminating allocator overhead, and they are pulled/pushed
from/to a heap very quickly so that what overhead remains is slight and
bounded.
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)
vvp/main.cc was including asm/page.h on GNU/Linux
systems, though that file does not often exist and
is not necessary.

This patch adds a new flag to vvp "-n" that can be used to make
$stop and hence <Control-C> act like $finish. This may be desired
when using vvp in a non-interactive environment.
The functor counters were left over from the v0.8 release. Rework
the counters to be relevent to the current state of vvp.

The runtime is a vvp runtime engine debug aid that allows for
detailed dump into a debug log. The trace is enabled by setting
the VVP_DEBUG variable and activating specific debug messages
in the vvp source.

as well as a user specified log file, set log
file to buffer lines.
Add vpi_flush function, and clear up some cunfused
return codes from other vpi functions.
Adjust $display and vcd/lxt messages to use the
standard output/log file.
