Update fork choice spec comment for clarity
I think this change more clearly specifies the intended behavior. Given the terseness of the spec's code representation, I think we should aim for as much clarity as possible.

Jacek Sieka 56309342c0
Use `Bytes32` for `error_message`
`ErrorMessage.error_message` is a leftover from an older version of SSZ
that was able to encode unbounded lists. This is no longer the case -
all collection types now have a fixed upper bound on length.

In general, the `error_message`, just like the `graffitti` field, should
not be interpreted in any particular way except for debugging and vanity
- as such, using the same type, a `Bytes32`, seems reasonable.

An alternative would be `List[byte, 256]` which maybe could be
"reasonably backwards compatible" with whatever clients are are doing
now - depending on how they are dealing with this field type that no
longer exists in the SSZ spec :) It would however be the only place
where `List[uintN, N]` is used in the current spec.

As an exercise, this could be considered a security issue since it's
essentially unbounded and undefined behaviour.

require blocks to be ordered consecutively in block range request
Per the spec, if I request range 5-10, it is permissible for a client to
answer with block 7, 9 - even if the blocks 5, 6 and 8 exist.

Because blocks 7 and 9 cannot be validated as they arrive in such a
request, it seems better to close this gap - this update adds the spec
language that forbids well-behaving clients from answering this way.
