fixes#6518
In a ZIP sync meeting we decided that:
* The minimum cost should be changed to 10000, in order to avoid
penalizing Orchard-using transactions too much relative to other
transactions.
* `low_fee_penalty` should be changed to 40000. This preserves the
property that a transaction paying less than the ZIP 317 conventional
fee is deprioritized relative to a min-cost, conventional-fee
transaction by a factor of 5, as in the original design.
* The recommended default for `mempooltxcostlimit` should remain at
80000000. Rationale: 80000000 was chosen so that the worst-case size
of the mempool would be equal to the worst-case size of 40 blocks,
which is the current default transaction expiry delta. That reasoning
still holds even with the above changes.
* `eviction_memory_entries` remains at 40000. It could have been lowered
given that there will now be at most 80000000/10000 = 8000 transactions
"in-flight", but it doesn't need to be because the rationale that
"40000 [RecentlyEvicted queue] entries can be stored in ~1.6 MB,
which is small compared to other node memory usage" still holds.

zcash/zcash#5987 added a bridge to `orchard::Bundle<Authorized, Amount>`
for `getrawtransaction`. This commit expands it to also cover the
consensus rules, by migrating over missing functionality from the
hand-written FFI methods, and exposing the Orchard `BatchValidator` type
directly (as with Sapling) instead of via the C++ `AuthValidator`
intermediary.
Part of zcash/zcash#6397.
As a pre-check inside `z_sendmany` we estimate the size of the
transaction that would be created, to confirm it won't exceed any
limits. We do this by creating a fake transaction with fake outputs and
measuring its size. In the case of Sapling recipients, we'd push an
empty `OutputDescription`.
In zcash/zcash#6459 we pulled in changes that improved type safety in
the Rust types. One of these changes was that the `cv` field in a
Sapling Output Description is now enforced at parsing time to be not
small order (where previously we enforced this at proof verification
time).
The two above paragraphs collide because when measuring the size of the
fake transaction, we convert a `CMutableTransaction` into a
`CTransaction`; this calls `UpdateHash` to pin its txid, and that causes
the transaction to be serialized and then parsed across the FFI. This
causes the null `OutputDescription` to reach the Rust parser which
treats it as invalid.
There are two solutions to this, which are used in various contexts:
- Avoid pushing a null `OutputDescription` into a `CMutableTransaction`.
This is the fix implemented in this PR for `z_sendmany`: we now call
`RandomInvalidOutputDescription()` which gives us a consensus-invalid
but parser-valid `OutputDescription`, suitable for estimating tx size.
- Use `UNSAFE_CTransaction` to avoid having `UpdateHash` be called on
construction. This type is used in tests where we explicitly want to
construct an invalid type in C++, for consensus checking purposes. One
of the `OutputDescription()` uses was in a test, but didn't trigger
the issue because the test was checking a different part of the
transaction being invalid. Technically no change is needed here;
however we now also call `RandomInvalidOutputDescription()` here for
uniformity.
Part of zcash/zcash#6509.
- Remove `std::optional` from a number of uses,
- simplify `GetUFVKMetadataForAddress` to `GetUFVKIdForAddress`, and
- add a new `GetUFVKMetadataForAddress` as a wrapper around
`GetUFVKMetadataForReceiver`.

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.
This adds two new CuckooCaches in validation, each caching whether all
of a transaction bundle's proofs and signatures were valid.
Bundles which match the validation cache never have proofs or signatures
added to the batch validators. For blocks where all transactions have
been previously observed in the mempool, the final validation of the
batches should be a no-op.
Part of zcash/zcash#6049.
This switches the Merkle tree logic for blocks to one that runs in constant (small) space.
The old code is moved to tests, and a new test is added that for various combinations of
block sizes, transaction positions to compute a branch for, and mutations:
* Verifies that the old code and new code agree for the Merkle root.
* Verifies that the old code and new code agree for the Merkle branch.
* Verifies that the computed Merkle branch is valid.
* Verifies that mutations don't change the Merkle root.
* Verifies that mutations are correctly detected.

Assume that when a wallet transaction has a valid block hash and transaction position
in it, the transaction is actually there. We're already trusting wallet data in a
much more fundamental way anyway.
To prevent backward compatibility issues, a new record is used for storing the
block locator in the wallet. Old wallets will see a wallet file synchronized up
to the genesis block, and rescan automatically.

The change to use Orchard batch validation now requires the Orchard
verifying key to be available even if there are no items in the batch.
For simplicity, we now load all verifying keys in the Boost tests.
Since the wallet ecosystem may not be fully updated to handle
v5 transaction parsing at the point of NU5 activation, some
nodes may prefer to construct V4 transactions when not including
Orchard transaction components.
This change adds a CLI flag that allows node users to specify
that preference.
