We've never released firmware using the alternatives mechanism and our build process makes that difficult anyway. This means that in every file we have ever built (except maybe by hand for testing) the listed alternative was 0. Make the alternative field in the TLVs part of the TLV number (thus expanding that to 32 bits); this gives us more TLV numbers (not really needed) and more importantly protects against rogue firmware files that actually do use the alternatives mechanism -- those will now be rejected since they don't contain any valid TLVs.
