[Tarantool-patches] [PATCH v2 luajit 03/26] test: separate LuaJIT helpers from ffi_util.inc

[Sergey Kaplun]

This patch moves common helpers from <LuaJIT-tests/common/ffi_util.inc>
into separate files by analogy with <common/expect_error.lua>. The
`include()` helper isn't touched since it is used in system dependend
tests, which won't be modified for now.
