[PATCH 0/2] Move info to src/ for SWIM

[Vladislav Shpilevoy]

First commit has enough explanation of this patchset but nonetheless
it is formally required so there it is.

SWIM is a forthcoming independent module which is going to live in
src/lib. And it will have a method swim.info() which dumps SWIM
state to Lua.

But SWIM will be written on C and should not depend on Lua. To
resolve the problem the patchset moves src/box/info to src/info
to make it usable in SWIM.

src/box/info is an interface which allows to dump something to Lua
without getting in touch with Lua API.

Second commit in the patchset removes some false comments about info
interface stating that it throws C++ exceptions.
