Authors are not forced to use the clang-format setting, but should
atleast be inspired by the style.
The only thing which is now not allowed are tabs for ident/alignment!
Currently plib/systemstate, pol/uvars, pol/ucfg, pol/multi/multidef
Next step should be to split them based on usage, since its currently a bit of include hell...
Created a new file (msghandl.cpp) and moved the code from pol.cpp there.
Moved related files to the "network" folder, where they belong. Fixed
include names... (we should make this relative to the project root!)
