From 6c6a2ae6fc964795304bbe7687e42b2b0cdf81b3 Mon Sep 17 00:00:00 2001
From: Richard Levitte <levitte@openssl.org>
Date: Mon, 5 Dec 2016 15:13:26 +0100
Subject: Test framework: Add the possibility to have a test specific data dir

This data directory is formed automatically by taking the recipe name
and changing '.t' to '_data'.  Files in there can be reached with the
new function data_file()
