Flash memory endurance

[mcolella]

Since the flash memory endurance is limited to 10000 cycles and there is no counter registry inside the MCU to keep count of how many time a sketch is loaded, in order to estimate remaining board life, how about to introduce a counter handled by bootloader (or something like this) to keep trace of total programming cycle?
Of course this counter should be accessible bay the sketch code...

The memory endurance is guaranteed at 100,000 cycles. But in reality, at least for ATmega328s made after 2014, it's in the millions.
