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.

0f724e716d Closes #1969. Default fee now sufficient for large shielded tx. 
Sets default min relay tx fee to 100, which is used to initialize
nSatoshisPerK for min fee calculation.  The default z_sendmany
fee of 10000 is now sufficient to cover a tx of size 100000 bytes,
so txs will not be treated as "free" and hit the free rate limiter.
