Now we can check that the setconfig would actually parse. We do this
by handing NULL to the calback to indicate it's a test, which may not
work in general but works for now.

Changelog-Added: `check` `setconfig` now checks that the new config setting would be valid.
To test, we do min-capacity-sat which is simple. We also update the
listconfigs man page which contained some obsolete information.

We have hacky code to show some listconfigs values as literals; instead
explicitly encode the types.

Clearly, listconfigs shouldn't list these.
Also, hoist the opt_hidden check since it's independent of whether
there's an arg or not.

These are gathered from the config files and the commandline, but the
process is rather complex! We want to remember where the options came
from in future (for a `setconfig` command), and also generalize
and simplify handling.
