Release 1.4.7

- Fix another old "BUG: Attempt to overwrite used offset" in a very simple
  case: bs=4k rw=write iodepth=16 from OSD start; add this case to tests
- Fix a rare crash with "unexpected state during flush: 0x51" possible with
  EC since 1.4.2 during rebalance and OSD outages
- Fix a rare write stall with EC & immediate_commit=none caused by sync
  operations reserving unneeded space in the journal
- Fix 32-bit build warnings, most in printf/scanf format strings
