[Tarantool-patches] [PATCH v3 0/6] qsync: write CONFIRM/ROLLBACK without txn engine

[Cyrill Gorcunov]

In this series we write CONFIRM/ROLLBACK messages into the WAL directly
without involving the txn engine.

Vlad, take a look please, once time permit.

issue https://github.com/tarantool/tarantool/issues/5129
branch gorcunov/gh-5129-journal-3

v3:
 - bootstrap journal left NULL for async write
 - journal_write_async_cb_t type for async callback
 - struct synchro_body_bin type for encoded message
 - xrow_encode_synchro helper to operate with synchro_body_bin

Cyrill Gorcunov (6):
  journal: drop redundant declaration
  journal: bind asynchronous write completion to an entry
  journal: add journal_entry_create helper
  qsync: provide a binary form of syncro entries
  qsync: implement direct write of CONFIRM/ROLLBACK into a journal
  qsync: drop no longer used encoding helpers
