Title: enabling the JSHint option undef:true, part 2 of fixes #10692

Either pick this PR or https://github.com/jquery/jquery/pull/601. Whichever one you're comfortable with!

This is code cleanup for the JSHint option undef:true. Obviously, please test the crap out of this. It passes unit tests in the browsers I have access to, but I'd love it if this could get some more heavy review as I obviously want to make sure this works 100%
