I would add a bit more context here. The original patch was made by
Sergey O. and I asked for extracting all related functions into its own
'module'. See links below.

The moving of just one function should be sufficient, you're right.
However it is not much more work then extracting all those related
function into tnx.{c,h,lua}. So I think it worth to do just here.

Are you agree that box/lua/txn.* is more proper place for those
functions then box/lua/schema.lua?
