Add iterators for EDID blocks and CEA data blocks, to iterate through all data blocks across all CEA extensions and CTA blocks in DisplayID data blocks. Fix all code assuming only one CEA extension. Fix code assuming CTA blocks contain everything that CEA extensions do. Sprinkle a bunch of cleanups on top. This is completely UNTESTED, didn't even smoke test it. It builds. ;) This superseeds parts of [1] and [2]. BR, Jani.
