sys: preprocessor successor module
Contribution description
Generate a header file, containing successor definitions up to a fixed maximum.
This allows to use the preprocessor to compute the successor of a number and is useful to construct priority values for auto_init.
This is similar to boost preprocessor arithmetik.
Testing procedure
See usage in tests/external_module_dirs/external_modules/external_module/external_module.c

I think this is useful for external modules to hook into the auto init code in a more robust fashion.
I think that @gdoffe and many @benpicco may be interested in this. IMO, this only needs a rebase to get in.
