This continues our ongoing effort to get a coherent chain of context.Context all the way from "package main" to all of our calls to external components. Context.Eval doesn't yet do anything with its new context, but we'll plumb this deeper in future. All of the _test.go file updates here are purely mechanical additions of the extra argument. No test is materially modified by this change, which is intentional to get some assurance that isn't a breaking change. Signed-off-by: Martin Atkins <mart@degeneration.co.uk>
