Vitaliy Filippov 1cec62d25d Sync only completed writes 
Should be a final remaining fix to EC + non-capacitor (non-immediate-commit) write hangs :).

First it was breaking non-EC ("instantly stable") writes because they sometimes
complete out of order which was leading to the following error:

terminate called after throwing an instance of 'std::runtime_error'
  what():  BUG: Unexpected dirty_entry 1000000000001:29480000 v65540 unstable state during flush: 0x151

But it is easily fixed by scanning previous and next dirty_entries in mark_stable.

Vitaliy Filippov b7e4d0c9bf Fix journal dirty_start position tracking and some debug prints 
Fixes two bugs found during HDD testing :-)
1) OSD crashed with "BUG: Attempt to overwrite used offset of the journal" during
   `fio -bs=900k -iodepth=128` test with 16 MB journal
2) OSD stalled during `fio -bs=512k -iodepth=128` test with 64 MB journal

Vitaliy Filippov 238037ae31 Make journal trimmer wait until reads are completed when inmemory_journal is false 
Without this new writes may in theory overwrite journal data being read at that time

Vitaliy Filippov f93491bc6c Implement journal write batching and slightly refactor journal writes 
Slightly reduces WA. For example, in 4K T1Q128 replicated randwrite tests
WA is reduced from ~3.6 to ~3.1, in T1Q64 from ~3.8 to ~3.4.

Only effective without no_same_sector_overwrites.

Vitaliy Filippov 98f1e2c277 Rework write/sync ordering 
Make syncs wait for all previous writes because it's the only way
to make sure that OSDs do not receive incomplete writes in LIST results
during peering when some writes are still in progress.

Also simplify blockstore submission queue logic.
