core: fix config.h

While exploring why logging is disabled but still shows up in the binaries
I kind of wondered how all the config.h HAVE_XX checks we have everwhere work.
Apparently they do not work at all, due to missing or misplaced include of config.h.

This affects tons of other checks as well.

The jenkins hook ensures the include order is checked to ensure config.h
does not get misplaced or lost in the future.
