ASSIGN transfer data to scheduler efficiently/permalloc vvp_net_t objects.
...
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

[PATCH] Removed #include asm/page.h on GNU/Linux
...
vvp/main.cc was including asm/page.h on GNU/Linux
systems, though that file does not often exist and
is not necessary.

Add vvp flag that allows $stop to act like $finish.
...
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.

Clean up functor counters
...

Start runtime trace aids
...
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.
