Remove LIST op limiter
...
It doesn't prevent OSD slow ops but may itself lead to stalls :)

Fix build under clang and some warnings
...
Build problems fixed:
- void* pointer arithmetic which is a GNU extension (works as byte*)
- "variable size object may not be initialized" which is OK under GCC
- nullptr_t related error in json11 (it lacks 'operator <' in clang)
Warnings fixed:
- empty nested struct initializer { 0 } replaced by {}
- removed several unused lambda captures

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.

Do not duplicate blockstore operations when io_uring fills up
...
This bug was leading to OSDs dying with "Assertion `fulfilled == read_op->len' failed"
when testing fio -rw=randread -numjobs=8 -iodepth=128

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.
