Comment (by nickm):
> Is this the expected behavior, or should it fallback to UINT64_MAX?
I think that's a better behavior for config_parse_memunit(). In the case
of config_parse_memunit(), it's better that the user be told about the
problem than to have us silently ignore their request.
> Should lib/intmath/*.h be appended to confmgt .may_include?
Yes, that's fine. The purpose of .may_include is to make sure that low-
level modules don't include headers from high-level modules, and
lib/intmath is a nice low-level module.
