be12669982 Add consensus branch ID parameter to SignatureHash, remove SigVersion parameter 
We do not need to be able to calculate multiple SignatureHash versions for a
single transaction format; instead, we use the transaction format to determine
the SigVersion.

The consensus branch ID *does* need to be passed in from the outside, as only
the caller knows the context in which the SignatureHash is being calculated
(ie. mempool acceptance vs. block validation).

JoinSplit signature verification has been moved into ContextualCheckTransaction,
where the consensus branch ID can be obtained.

The argument to the sign command for zcash-tx has been modified to take a height
in addition to the optional sigtype flags.

49274558c6 Auto merge of #2940 - str4d:nu-activation-mempool-expiry, r=str4d 
Mempool improvements, branch ID awareness

Whenever the local chain tip is updated, transactions in the mempool which commit to an
unmineable branch ID (for example, just before a network upgrade activates, where the
next block will have a different branch ID) will be removed.

Includes commits cherry-picked from the following upstream PRs:

- bitcoin/bitcoin#6654
  - Only the mempool index change.
- bitcoin/bitcoin#6776
- bitcoin/bitcoin#7020
- bitcoin/bitcoin#6915

Part of #2074.

cb580c7241 Add rollback limit to block index rewinding 
This will prevent users from starting their nodes if they switch between
software versions that implement different network upgrades. It will also
prevent users from using the testnet if they have more than MAX_REORG_LIMIT
post-upgrade blocks, and the upgrade point is shifted in a newer software
version.

External linkage does not help and just encourages sloppy dependencies
and can lead to weird issues when there are name collisions.

Delta values will be stored for new blocks; old blocks can be filled in by
re-indexing. The net value currently in the Sprout circuit is only calculated
when delta values for all previous blocks are present.
