Hi Kevin.

yes. I started with an icarus branch (gnucap-icarus) i found in a
gnucap+ git repo. it seems this is equal to the branch you are pointing
at.

in the meantime ive changed/rewrote most of it. in roughly chronological
order i wrote a gnucap device (replacing the subckt), and replaced the V
and I netlist with gnucap logic. i then skipped the vvp assembly file,
direcly spelling out the compile calls (moving away from tgt-vvp).
finally i moved to an unhacked vvp, doing the event queue on gnucap
side. this seemed natural as the needed extra opcodes for notification
and parameter injection have nothing to do with upstream vvp.

as it was pointed out many times, it would totally make sense to remove
the rest of vvp as well (this seems to be particularly simple now, but i
havent figured out all the details yet).
