Verify that there are at most `MAX_SPECIALS_PER_BLOCK` objects in `block.specials`. Verify that the quantity of each type of object in `block.specials` is less than or equal to its maximum (see table at the top).
For each `SpecialRecord` `obj` in `block.specials`, verify that its `kind` is one of the below values, and that `obj.data` deserializes according to the format for the given `kind`, then process it. The word "verify" when used below means that if the given verification check fails, the block containing that `SpecialRecord` is invalid.
