[PATCH 00/11] SWIM preparation

[Vladislav Shpilevoy]

SWIM is going to use evio to bind to an address, specified by a
user. Evio encapsulates bind/rebind, diagnostics, socket family.

But evio is C++ and SWIM is C. The patchset converts evio to C
alongside with sio, which is used in evio.

During conversion several not critical bugs were found and fixed
in separate commits.
