Remove title attributes trac tickets

I’ve created all new tickets for each file referenced from the original remove title attributes trac ticket (https://core.trac.wordpress.org/ticket/24766). I originally split it up into 17 separate tickets, but closed 3 of them already, because they had already been committed into 3.8 or earlier.

I’ve added comments and/or patches, as relevant, on all of the remaining tickets – so please chime in with opinions as relevant! Many of these incorporate situations where a 2nd opinion would be valuable, because the title attribute incorporates relevant information and some alternative handling may be necessary.
