These were removed in PR 9170, since they were unused in the browsers that we'll support in PDF.js version `2.0`. However looking at the output of Travis, where a subset of the unit-tests are run using Node.js, there's warnings about `btoa` being undefined. This doesn't appear to cause any errors, which probably explains why we didn't notice this before (despite PR 9201).
