It's still a library function. As said earlier, I think _all_
of what's now in lib.c should move to lib/. That's how it
should have been from the beginning, or stuff shouldn't have
been put in lib.c.

The one alternative I see is to move the code next to
parse_bool() / parse_boolean(), in kernel.c, or put all
parse_*() into a new common/parse.c.
