I think I managed to update all call sites using wsgirequest.form
to use parsedrequest.qsparams.
Since behavior of qsparams is to retrieve last value, behavior will
change if a parameter was specified multiple times. But I think this
I'm not a fan of the req.req.qsparams pattern. And some of the
modified code could be written better. But I was aiming for a
straight port with this change. Cleanup can come later.
