[tarantool-patches] [PATCH 0/6] swim suspicion

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

For details of the suspicion component look at the last commit. Here is a
description of the patchset in whole.

Most of the commits are preparatory patches to make suspicion introduction
smoother. First 4 commits refactor the code so as to make it more readable, to
simplify writing new tests.

Next to the last patch about routing is in fact the key part of the patchset. It
introduces new section in SWIM packets for routes. Route is a pair: source and
destination addresses. With help of the routing it becomes possible to send any
SWIM packets indirectly via arbitrary SWIM member to another member.

The last commit just harnesses routing section to send the same ping/ack
messages, but indirectly after several direct attempts.
