Partial fix for #1701
Clarify that state transitions with `uint64` overflows are invalid.

Fix #1735—remove redundant check
As per #1735 the check `if not len(indices) <= MAX_VALIDATORS_PER_COMMITTEE: return False` is redundant. As such this PR should be purely cosmetic.

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.

Hsiao-Wei Wang c10e59bdf7
Fix `INACTIVITY_PENALTY_QUOTIENT`
The amount of inactivity penalty was adjusted to half since we were applying penalty for missing FFG target and source. But now we only apply it for missing target, so `INACTIVITY_PENALTY_QUOTIENT` should be `2**24`.

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.

drop `head_block_root` from BeaconBlocksByRange
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.
