[tarantool-patches] [PATCH v3 0/2] Transaction boundaries in replication protocol

[Georgy Kirichenko <georgy@tarantool.org>]

This patchset introduces transactional replication and consist of two
commits:
 * the first one forms transaction boundaries in a xlog
 * the second one forms transactions in applier buffers and then
   applies them with correct begin/commit boundaries.


Note: distributed transaction are not supported so we form a
separate transaction for all local triggers effects.

Changes in v3:
 - Change encoding in order to achieve better compaction
 - Transactional replication test

Changes in v2:
 - Rebased against latest 2.1
 - Fixed extraction for local replication effects
