Thomas Kolb d6eaef91cd Switch to new logging system
The new system supports:

- time-tagging of log messages
- message priority levels with a threshold below which they are not printed
- colored output of the message priority for easy identification
- compile-time disabling of all logging per C module

So far, it is integrated in the main and rx modules which generate most
messages. Other modules will be migrated in the future.
