[Tarantool-patches] [PATCH 2.X v2.1 1/4] module api: export box_tuple_validate

[Timur Safin <tsafin@tarantool.org>]

For external merger we need means to validate tuple data,
thus exporting `box_tuple_validate` which is wrapper around
`tuple_validate_raw` without revealing access to tuple
internals.
