For consistency, we serialize the `finalState` field in the
same (sparse) encoding as Sapling and Sprout use. In the future
we may want to update this to the dense encoding that
incrementalmerkletree::bridgetree::Frontier uses, but that's not
necessary for the moment.
This adds tests to wallet_z_sendmany that demonstrates conditions
where pool-crossing transfers were not being caught by the privacy
policy checks, which were validating only against the transfer
request rather than the actual transfer selected. This missed
cases where sending funds between unified addresses would reveal
amounts via the turnstile.
Making all privacy policy checks after note selection guards against
this error.
If a new Orchard wallet is created after the first Orchard spend
post NU5 activation, it causes an assertion failure because the root
of the wallet's empty note commitment tree does not match the global
note commitment tree root.
The test fails during the final `z_sendmany`, because it is selecting a
note that was detected before restarting the node. Because we force the
wallet to call `SetBestChain` on every block, the wallet doesn't need to
rescan on restart, and thus doesn't repopulate the `position` field of
the in-memory note.
This issue went unnoticed in existing tests that exercise node restarts,
because the RPC tests are fast enough that they never pass the 10-minute
timeout for writing the wallet state. This commit adds a regtest-only
config option that disables the lazy writing.
Make consistent use of "pool", "address type" and "receiver type",
in RPC documentaion, and deprecate bare uses of "type" in RPC APIs.

Orchard output ordering is no longer deterministic, as we now shuffle
spends and outputs during bundle building. But we _can_ still check that
the action index of a note being spent is correct.
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).
- The legacy_random source should only contain Sprout addresses (as
zcashd now only derives transparent addresses from the mnemonic seed).
- Sapling addresses should appear in the mnemonic_seed source, not the
legacy_seed source (as zcashd no longer ever generates keys there).
The RPC test also now has several additional checks:
- `listaddresses` does not return duplicate addresses (an address can
only come from a single source).
- Address sets are now explicitly checked (to ensure that there are no
unexpected addresses under the checked sources).
