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.
