Reduce struct node size 

* Replace the stat values with a crc32b of them instead (for auto-cache)
* Replace char flag with bitfield
* Remove node generation. nodeid is an unsigned 64bit int. Would take 500K+ years
  to rollover at 1M nodes per second.

nodeid is uint64_t: max value of 18446744073709551616

over 500 thousand years to roll over. I'm fine with risking that.
