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.

I considered updating jsonlogger.c to represent NaN as "null" in the

complicated.
