4915014a19 simplify block range request description 
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.

2daa26442b 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.

88fddf2379 Remove unneccessary clock disparity check 
There is no need to mention clock disparity when comparing two static slot values (assuming the clock disparity is less than a slot, even then I don't think that's the intention).

52b45ab9de 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.
