Lint errors

[steveri]

2-unit verilator runs seem to give the most lint errors:

% less tst/regress/examples/190703.log
...
vcs    8  1 1port PASS -   x warnings,    15 lint problems
vcs    8  2 1port PASS -   x warnings,    72 lint problems
vcs    8  4 1port FAIL -   x warnings,     0 lint problems (*)
ver    8  1 1port PASS -   x warnings,    71 lint problems
ver    8  2 1port PASS -   x warnings,   139 lint problems
ver    8  4 1port FAIL -   x warnings,     0 lint problems (*)

(*) NOTE 8-4-1 is supposed to fail...

May as well start with 8-1-1. Plan would be something like

1. mkdir lint; cd lint
2. make -f ../Makefile gen |& tee gen.log0
3. make -f ../Makefile run_verilator |& tee run.log0
4. resolve lint errors by editing elaborated verilog in genesis_veri-whatever
5. goto 3, repeat until lint errors are gone
6. propagate edits to .vp generator files
7. goto 2, repeat until errors are gone
