hood file: Use different files for www and for checksum comparison
At the moment, we use the same file for detecting changes in a new hood file and for broadcasting the hood information to be used by mesh routers. However, there may be situations where we don't want to broadcast an existing hoodfile. We, on the other hand, cannot delete it then, as we need the file for checking changes in the temporary hoodfile. We also cannot just switch the wXconfig state to achieve this goal, as we need a trigger to do that (which is the same file we are discussing about). So, in this patch, we introduce two files, one for the checksum comparison and one for the hood info broadcast. Those can now be set and deleted (in a later patch) as it is required by their respective tasks. This should also improve code clarity to the reader ...
