Andreas Kling eeddaa988a ConfigServer+LibConfig: Add pledge_domains() API
This API lets applications specify which configuration domains they
will be accessing throughout their lifetime. It works similarly in
spirit to the kernel's pledge().

You cannot pledge_domains() more than once, and once you have used it,
it's no longer possible to access any other configuration domain.

This is obviously just a first cut of this mechanism, and we may need
to tweak it further as we go.
