[tarantool-patches] [PATCH v2 0/3] Transaction boundaries for applier

[Georgy Kirichenko]

This patchset consists of three patches.
* The first one removes xstream dependency from applier.
* The second one creates a separate journal transaction for all local
  effects in case of replication what is needed to be able to replicate
  such effects back.
* The third one turns applier into transaction mode - an applier first
  fetches the whole transaction and then applies all rows within
  transaction boundaries.

Changes in v2:
 * Get rid of apply_initial_journal_row and apply_row from box.cc and
   purge box dependency from applier.
 * txn.cc and txn.h changes moved into a separate commit.
 * applier_read_tx uses stailq to form a list of rows in a transaction.
 * use exceptions for applier routines.
 * slight changes according to review.
