logilab-common #298658 generated config has unstable section ordering [validation pending]

Craig Hobbs reported on the mailing list:

This causes generated rcfiles (like those of pylint) to be output with random section order. The fix is simple - just sort the section item iteration (see below).

Bug can be reproduced with python 2 using PYTHONHASHSEED=random.
