Add option to disable multiple overwrites of the same journal sector
...
This makes sense for some SSDs like Intel D3-4510 because they don't
like overwrites of the same sector:
$ fio -direct=1 -rw=write -bs=4k -size=4k -loops=100000 -iodepth=1
write: IOPS=3142, BW=12.3MiB/s (12.9MB/s)(97.9MiB/7977msec)
$ fio -direct=1 -rw=write -bs=4k -size=128k -loops=100000 -iodepth=1
write: IOPS=20.8k, BW=81.4MiB/s (85.3MB/s)(543MiB/6675msec)

Several bug fixes
...
- Do not block flock() requests
- Fix stop_client(0) attempts leading to std::bad_function_call
- Fix degraded writes crashing due to an unset stripes[i].missing (at least with a missing parity device)
- Fix recovery B/W reporting
