The old scheme of linking the VPI modules with the vvp exports meant they
did not work when loaded by the compiler. Instead, let each client create
a jump table for the VPI routines and pass that to each VPI module as it
is loaded.
Update the line number for a couple cppcheck suppressions and add one for
the pool variable in the vvp directory.
Also move a check for null to the correct place.
