[Tarantool-patches] [PATCH v19 0/3] qsync: implement packet filtering (part 1)

[Cyrill Gorcunov]

Please take a look once time permit.

v19 (by Vlad):
 - do not modify box_issue_promote and demote (while they are
   still simply utter code duplication but whatever)
 - make txn_limbo_process being void
 - make txn_limbo_process_begin/commit/rollback being void
 - the real processing of request under the lock named as
   txn_limbo_process_core
 - testcase completely reworked (kudos to SergeP)
 - note that if we import test to the master branch without
   ordering pass it will fire assertion
 - dropped off debug info from box.info interface

Guys, also I noted that the test while being passed pretty fine locally
sometimes doesn't pass on CI due to timeout in waiting record {2} propagation,
so any advices on the test is quite welcome!
