Layer 1 only does decoding of the FEC, but the CRC check for data integrity is
done in layer 2 now.

Thomas Kolb 0e8e049e0a Replace all perror() calls with LOG() 2024-05-30 11:02:08 +02:00
Thomas Kolb 65daa182ef Use the new logging system everywhere 2024-05-30 10:49:43 +02:00
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.
