@proppy - Is this pull request worth rebasing and landing now?

[proppy]

＠mithro this needs to be rebase against internal BUILD file changes (the iverilog project file structure changed quite a bit in 5 years)

Looks like cocotb tests fail because of the way vvp and iverilog are invoked:

Step #1: //cocotb/tests:cocotb_counter                                            FAILED in 0.3s

with the following error:

Unable to find dependencies (looking under /home/proppy/.cache/bazel/_bazel_proppy/530ec4e06f73c694e11ff02f6133cd51/sandbox/linux-sandbox/2694/execroot/rules_hdl/bazel-out/k8-fastbuild/bin/cocotb/tests/cocotb_runner.sh.runfiles/rules_hdl/external/com_icarus_iverilog/iverilog.runfiles/com_icarus_iverilog).

while the files themselves are in:
