[Tarantool-patches] [PATCH 00/12] Raft module, part 2 - relocation to src/lib/raft

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

The patchset is a second part of Raft relocation to a new module for the sake of
unit testing. This part does the relocation itself.

It entirely consists of removal of box dependencies from raft code.

The third part will virtualize Raft event loop at compile-time, and will
introduce customizable implementations for network, disk, event loop, and time
to perform unit tests.
