RFC: Circular log buffer

[bergzand]

While testing something out, I got a bit annoyed by uhcpc spewing log messages directly in my serial console 😞.
I was thinking that on nodes with a bit of ram to spare, a circular log buffer would be a valuable addition. a KB of ram dedicated to log messages, set up as a circular log buffer. This could then be read out by a shell command or even over CoAP in environments where there is no shell access.

Kind of like syslog with logrotate on Linux? I like this idea, especially being blue to read the log through coap or even through the debugger when trying to fix UART issues 👍

[bergzand]

Yes, the linux kernel log (dmesg) might be the better analogy, but the idea is clear.

I also think that if this project is going to support slipmux, this might be the way to do the message logging.
