===============
This hotfix remediates memory exhaustion vulnerabilities that zcashd inherited
as a fork of bitcoind. These bugs could allow an attacker to use peer-to-peer
messages to fill the memory of a node, resulting in a crash.

1000 blocks was selected as a balance between limiting the likely
maximum memory usage of the batch scanner, and avoiding
artificially restricting scanning throughput of small/fast blocks
due to the second-boundary lock synchronization point.
This also removes the `zcashd.wallet.batchscanner.usage.bytes` gague
value that was previously made available when `-prometheusport` was
specified.

These features were deprecated at least 3 minor releases ago. I found
one mistake which was that `z_validateaddress` had not been placed
behind the `addrtype` deprecated feature; this has been fixed.
The RPC method handler is left in as a tombstone, to redirect callers to
the replacement method (as this is an upstream Bitcoin Core RPC method
that users may expect to be present).
