sparse: require [section] in sparse config files (BC)

Previously, [include] was implicit and pattern lines before a
[section] were added to includes.

Because the format may change in the future and explicit behavior,
well, more explicit, this commit changes the config parser to
reject pattern lines that don't occur in a [section].

# showstack.py - extension to dump a Python stack trace on signal
