[comm] First run of error checking normalization
[primary_robot/lpc_prop] Improves debugability
Merge branch 'dev_err_check'
[comm;lpc;net_cfg] Several minor fixes, typo, debug
[comm/arduino/I²C] Fixes major bug causing messages loss
* Yes, the I²C doesn't need delays to work properly...
* It was mutexUnlock() which was reenabling interrupts in isr causing data corruption
* With those evil delays it just delayed enough the next message so that the previous one is already handled and out of isr
* And btw, it only "fixed" the arduino to arduino side of the problem... a very rare scenario in our architecture...

* A better name for mutex{Unl,L}ock would be atomic{Begin,End}
[comm/botNet_core] Fixes future possible bug using bn_popInBuf()
* Copy the right size of data and the interface
* Keep the "mutex" locked while you need the data
