Unittest coverage initialization and including .c files

• Increase coverage of connection_manager.c #470

That does not work because c99 does not compile as c++ in this case, and because there probably would be symbol clashes as not everything is declared static. Would need intermediate c file that will reexport some static things, and somehow control the symbol clashes. either new test binary for every included .c, or somehow limit visibility for an .o file, if that is even possible.
