Please note that the `glyphlist.js` and `unicode.js` files are converted to CommonJS modules instead, since Babel cannot handle files that large and they are thus excluded from transpilation.
Please see http://eslint.org/docs/rules/object-shorthand.
For the most part, these changes are of the search-and-replace kind, and the previously enabled `no-undef` rule should complement the tests in helping ensure that no stupid errors crept into to the patch.
I happened to notice that some inequalities had the wrong order, and was surprised since I thought that the `yoda` rule should have caught that.
However, reading http://eslint.org/docs/rules/yoda#options a bit more closely than previously, it's quite obvious that the `onlyEquality` option does *exactly* what its name suggests. Hence I think that it makes sense to adjust the options such that only ranges are allowed instead.
Note that in `parseCodestream` I purposly left the `throw new Error` instances inside of the `try` block, since we don't want to throw any `Errors` while in recovery mode.
Finally somewhat unrelated to the rest of the patch, but I moved the `doNotRecover` variable declaration outside of the `try` block to avoid variable hoisting given that it's accessed inside the `catch` block.
This patch makes the image from #5349 appear correctly, the artefacts
for the last packet are fixed in #5426.
This patch also optimizes some "in-checks" and adds a few header parsings.
