Fix var conversions that ESLint could not do automatically
This mainly involves the `crypto_spec.js` file which declared most
variables before their usage, which is not really consistent with the
rest of the codebase. This also required reformatting some long arrays
in that file because otherwise we would exceed the 80 character line
limit. Overall, this makes the code more readable.
