network upgrades:
* after Blossom, there is an extra halving of the block reward;
* after NU5, `nExpiryHeight` must be equal to the block height;
* after NU6, we need to take into account the lockbox value.
Also we rename `hashFinalSaplingRoot` to `hashBlockCommitments`,
and make `CBlock.rehash` implicitly recalculate the `hashMerkleRoot`
and `hashAuthDataRoot` fields.

This also updates to zcash/librustzcash@5a4a3e06dc
in order to ensure consistency between constants defined in librustzcash
and the constants defined here.
* used "fee" to mean "fee rate", "kB" to mean 1000 bytes, "satoshis"
to mean zatoshis, or that incorrectly used "BTC" in place of "ZEC";
* used obsolete concepts such as "zero fee" or "free transaction"; or
* did not accurately document their applicability.
Uses of "satoshis" as a JSON key are not altered.

Remove all coin age priority functionality from unit tests and RPC tests.
(cherry picked from commit bitcoin/bitcoin@0315888d0d)
Zcash:
* We cannot remove the `pool` parameter from the `CTxMemPool` constructor
because we do not have bitcoin/bitcoin#9138. (Backporting that PR is
unnecessary and would be a distraction from the purpose of this one;
the changes made by it are orthgonal.)
* We don't have `prioritise_transaction.py`, `MempoolAncestorIndexingTest`,
`MempoolSizeLimitTest`, or the `estimateSmartFee` functionality, so omit
the changes for those.

- still support explicit fixed fees everywhere – if a caller provides a fee, we
don’t adjust it
- treat negative fees as signifier for use of ZIP 317 fees when a fee needs to
be provided because of additional positional arguments
and an incompatibility with Python 3.9 in the test framework that
affected the `receivedby` extended RPC test.

Without this fix we will get:
AttributeError: 'SpendDescriptionV5' object has no attribute 'anchor'
On certain V5 transactions rehash / calc_sha256, for example:

This change improves clock management for zcashd by ensuring
that all clock methods (obtaining seconds, milliseconds, and
microseconds since the epoch) agree under testing conditions
using `-mocktime`, and also adds a feature that allows tests
to specify an offset to the system clock; this is useful to
allow comprehensive testing of the "timejacking attack mitigation"
consensus rules.
That is, without having to launch with test_runner.py. There are
several places where the BITCOIND environment variable determines the
executable, but the default is "bitcoind"; change the default to
"src/zcashd". This does require running the test from the top-level
directory.
Also change the environment variable from BITCOIND to ZCASHD. This could
conceivable break someone, but it just makes too much sense not to do.
Also fixes a bug in the `nuparams` helper, which would have caused MSB
zeroes in consensus branch IDs to not be rendered in the `-nuparams`
option. This hadn't been encountered because we haven't yet generated a
consensus branch ID with a zero MSB.
We need to bump the `zcashd` protocol version because the new rules are
not compatible with existing rules followed by 170015 nodes, but we
_also_ need to ensure we can still bump it again once we set the testnet
reactivation height (changing node network behaviour again). This commit
also enables RPC tests to run (because previously the nodes considered
each other to be too old for NU5 to be active, and were disconnecting).
This includes:
- `orchard =0.1.0-beta.3` which includes the final circuit changes.
- The new NU5 consensus branch ID.
- Updated ZIP 244 test vectors (which use the NU5 consensus branch ID).
