plugins: allow to configure through multiple call sites

This is the glue needed to be entirely plugin-agnostic, it only
needs new hooks for spots we haven't pluginified yet.  The dns
subsystem is another likely candidate in the long run.

Allows to move these plugins away from core: bsnmpd, igmpproxy,
relayd, miniupnpd.  ACL and menu entries pending...
