[Tarantool-patches] [PATCH 0/3] Replication status errno

[Vladislav Shpilevoy <v.shpilevoy@tarantool.org>]

The patchset makes box.info.replication*.upstream/downstream show
errno description for system errors.

I made that it shows strerror(errno) of the latest system error,
but probably it would be better to show errno value, and let a
user to translate it manually using Lua errno module. On the other
hand my way is simpler for a user when he manually calls box.info
in a console to check a replication status. That is discussable.
