[tarantool-patches] [PATCH v3 0/2] Transaction boundaries for applier

[Georgy Kirichenko <georgy@tarantool.org>]

This patchset consists of thwo patches.
* The first 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 second one turns applier into transaction mode - an applier first
  fetches the whole transaction and then applies all rows within
  transaction boundaries.

Changes in v3:
 * rebased against latest 2.1.
 * use n_local_rows/n_remote_rows counters.
 * fixes and refactoring according to review.

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.
