[Tarantool-patches] [PATCH v9 0/5] limbo: implement packets filtering

[Cyrill Gorcunov]

Replication tests are passing but gihutb tests are not: the series
is on top of Serge's branch `sp/gh-6034-empty-limbo-transition` which
is failing yet.

Vlad, I removed txn_limb_terms structure which made me to rework
the series, please take a look if you have some other comments
to address.

branch gorcunov/gh-6036-rollback-confirm-09-notest
issue https://github.com/tarantool/tarantool/issues/6036

v6:
 - use txn_limbo_terms name for structure
 - rebase on fresh sp/gh-6034-empty-limbo-transition branch
 - rework filtering chains
v8:
 - add ability to disable filtering for local recovery
   and join stages
 - update tests
v9:
 - opencode terms tracking
 - fix tests to use wait function since log output might
   be deferred by OS

Cyrill Gorcunov (5):
  latch: add latch_is_locked helper
  say: introduce panic_on helper
  limbo: order access to the limbo terms
  limbo: filter incoming synchro requests
  test: add replication/gh-6036-rollback-confirm
