assert PARSE_OPT_NONEG in parse-options callbacks
In the spirit of 517fe807d6 (assert NOARG/NONEG behavior of
parse-options callbacks, 2018-11-05), let's cover some parse-options
callbacks which expect to be used with PARSE_OPT_NONEG but don't
explicitly assert that this is the case. These callbacks are all used
correctly in the current code, but this will help document their
expectations and future-proof the code.
As a bonus, it also silences -Wunused-parameters (these were added since
the initial sweep of 517fe807d6, and we can't yet turn on
-Wunused-parameters to remind people because it has too many existing
false positives).
