[tarantool-patches] [PATCH v2 0/3] 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.

Second 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.

Changes in V2:
- added UUID to struct swim_task;
- dropped swim_iping_block structure;
- a few changes in parameter names and comments.
