[ESPResSo-devel] Simplified adding features

[Olaf Lenz]

Hi everybody!

As of now, handling features (a.k.a. compiler switches) in ESPResSo has
become significantly simpler for developers.

Instead of having to add a new feature in config.h, config.c,
myconfig-sample.h, etc., you now have to modify only the single file
src/features.def. In this files, the features are defined in a specific
simple way. Just have a look at the file, I hope it is self-explanatory.

From this file, the above files are automatically generated via a couple
of Python scripts.

What is more, the feature definitions can be used to do a number of
automatic checks:

* Does Jenkins actually compile all features (i.e. are all features used
in testsuite/configs/myconfig-*.h?)

* Are all features documented?

* Are all compiler switches that are used in the code actually defined
in features.def?

* Are all tests in the testsuite run by Jenkins?

Using this, I have already identified some problems in the code. I will
bug some of you with them during the next days. Stay tuned.
