[Tarantool-patches] [PATCH 0/7] Stacked diagnostics area

[Nikita Pettik]

Branch: https://github.com/tarantool/tarantool/commits/np/gh-1148-stacked-diag
Issue:
https://github.com/tarantool/tarantool/issues/1148
https://github.com/tarantool/tarantool/issues/4778

Patch-set basically consists of two parts: first one fixes undocumented
behaviour of box.error.new() which sets created error to diagnostics
area. The reason why it is required is described in the corresponding
github ticked. Second part is about stacked diagnostics itself: patch
error structure extending it with double linked list, provide Lua and
C interfaces to interact with it, support stacked diagnostics in IProto
protocol and net.box module (all points according to the rfc: 
https://github.com/tarantool/tarantool/commit/1acd32d98f628431429b427df19caa9d269bb9c8).
