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.

There's room for ambiguity as to what `count` means - this clarifies
that it always relates to the slot, and not the number of blocks in the
response which allows clients to request ranges epoch by epoch (for
example) without worrying about overlaps caused by empty slots.

Tighten restriction on a "seen" attestation
...
Declares that only a verified block can stop an attestation from being propagated.
This achieves two things:
1. Ensures that clients don't need to scan invalid blocks for attestations and then modify their state based upon them.
1. Disallows "muting" attestations by sending around a junk block with that attestation in it.

Add fork version to topic
...
Gossipsub peers are separate from the ETH2 RPC protocol, and thus cannot
rely on the application-level `Status` negotiation to establish if
they're on the same network.
Segregating gossipsub topics by fork version decouples RPC from gossip
further and allows peers to more easily listen only to the traffic of
the network they're interested in, without further negotiation.

This change simplifies the protocol and removes a race condition between
block request and response. In the case of honest server, this helps
serve the canonical / fork-chosen chain better while dishonest or broken
servers still need to be handled the same way.
Might as well get started on versions and upgrade it to 2, since the
change is backwards incompatible.
