config: add helper function for parsing key names
The config callback functions get keys of the general form: section.subsection.key (where the subsection may be contain arbitrary data, or may be missing). For matching keys without subsections, it is simple enough to call "strcmp". Matching keys with subsections is a little more complicated, and each callback does it in an ad-hoc way, usually involving error-prone pointer arithmetic. Let's provide a helper that keeps the pointer arithmetic all in one place.
