This commit alters the behavior of the `Read::read_to_end()` method to zero all memory instead of passing an uninitialized buffer to `read`. This change is motivated by the [discussion on the internals forum][discuss] where the conclusion has been that the standard library will not expose uninitialized memory. [discuss]: http://internals.rust-lang.org/t/uninitialized-memory/1652 Closes rust-lang#20314
