I've come to realize that many new users struggle with what to include into their application and realized that while we have a good API documentation there is no specific information how to include a certain component. There is some general information about USEMODULE in the doc, but no information about what to add to USEMODULE if I want to include the e.g. net/gnrc/pktbuf.h in your project.

My proposal is that the first section of each module API doc should name the module(s) required for the functionality.

This is a lot of work so before I start it I would like your opinion on that.
