[B.A.T.M.A.N.] [PATCHv2 1/4] batman-adv: Remove explicit compat.h include and split compat.h
The current approach for the compat layer is to include the compat.h file at exactly the right time to provide additional functionality and to live patch the batman-adv sources. This has the problem that the compat.h file becomes harder to read over time. Also live patching and adding of missing functionality partially conflict. This becomes obvious when the include order in some files is different compared to the one the author of an compat.h entry expected.
A different approach is to inject intermediate header files which add additional features. This allows to reduce the size of compat.h and only leaves the live patching part in it. The compat.h can then added automatically to each compile run before anything else is included. compat.h has therefore the control which headers must be included before the live patching of the batman-adv source can begin.

The header files could not be build indepdent from each other. This is happened because headers didn't include the files for things they've used. This was problematic because the success of a build depended on the knowledge about the right order of local includes.
Also source files were not including everything they've used explicitly. Instead they required that transitive includes are always stable. This is problematic because some transitive includes are not obvious, depend on config settings and may not be stable in the future.
The order for include blocks are:
* primary headers (main.h and the *.h file of a *.c file) * global linux headers * required local headers * extra forward declarations for pointers in function/struct declarations
