lib/_tls_common.js had instances of for loops that defined variables
with var such that they were re-declared in the same scope. This
change scopes those variables with let so that they are not
re-declared.

Why wasn't this catched by the linter?

@ChALkeR We don't (yet) have the no-redeclare rule turned on.

In the current code base, that rule fires 227 times.

While that may or may not be an acceptable amount of churn for enabling the rule, I'm not so sure that the fixes don't require some examination and thought for each one. It's not always as simple as "oh, just change it from var to const" or "declare it once at the top" or whatever. Or at least sometimes "declare it once at the top" isn't always the best solution. (This change, in this PR, is an example of that, I think. It makes sense for the variables to be scoped and not hoisted here.) So, I'm doing little digestible bits and pieces.

@ChALkeR If it's useful at all, here's the results of turning on no-redeclare on current master: https://gist.github.com/Trott/7dc16adf550b6a8d06cc
