[Tarantool-patches] [PATCH v2 luajit 0/5] Adapt lua-Harness test suite

[Igor Munkin]

Sergey,

Thanks for the series! I've looked onto the updated version on your
branch and it is almost cool! I've polished it a bit: commit message,
typos, etc -- you can see the changes on my branch[1] (CI is green[2]).
If you're OK with them, I'll push the changeset to the trunk.

Speaking about the changes in Tarantool, I almost OK with them except
the test/luajit-test-init.lua. Consider the comments below.
