* POLLOG* macros use the new formatting
removed all old logging functions
* removed old fmt lib from everything except StreamWriter
removed unneeded functions
* fixed review comments
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...
