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.

jsonlogger: increase pipe buffer to reduce likelihood of corrupted messages
...
Our JSON messages can get rather large which can cause a buffer overrun
when the reading program is not scheduled at the same time. When the
kernel returns EAGAIN we abort writing the current JSON message.
However, the unfinished (and thus invalid) JSON message is still in the
pipe and will be processed by the reading program.
Increase the pipe buffer from the default 65536 to reduce the likelihood
of this happening. It's difficult to completely prevent the issue as we
don't want to slow down the main program due to slow logging.
