* Rebuild trees when forking; change finalized state tree getters to not require height
* Pass empty trees to tests; use empty trees by default in Chain
* Also rebuild anchor sets when forking
* Use empty tree as default in finalized state tree getters (for now)

* Reduce DEFAULT_PARTIAL_CHAIN_PROPTEST_CASES and MAX_PARTIAL_CHAIN_BLOCKS
* Reduce DEFAULT_PARTIAL_CHAIN_PROPTEST_CASES and MAX_PARTIAL_CHAIN_BLOCKS even more

* Remove Sprout code, which will be moved to another branch
* Add todo! in Sprout tree append()
* Remove stub request, response *Anchor* handling for now
* Add test for validating Sapling note commitment tree using test blocks

* Add the constraint name to the Amount debug format
* Test consensus-critical serialization for Amount
Previously we were testing `serde` and `bincode` serialization,
which uses a completely different code path.

* Update versions for zebra v1.0.0-alpha.12 release
* Update Cargo.lock
* Update release checklist with latest version changes to help keep track for future releases
* Remove reference to the fact that tower-fallback was not updated
* Refactor to create `verify_sapling_shielded_data`
Move the code to verify Sapling shielded data into a new helper method
that returns `AsyncChecks`.
* Test verifying a Sapling transaction with spends
Use the test vectors to find a transaction that has Sapling spends and
test if it the verifier considers it valid.
* Create a helper method to list test transactions
Transforms the block test vectors into a list of transactions and block
heights for each transaction.
* Use new helper function in V4 Sapling spend test
Also use the block height for that transaction as specified in the test
vector.
* Test V4 tx. with Sapling outputs but no spends
Find a transaction V4 vector that has Sapling outputs but no spends, and
check that the verifier accepts it.
* Update multiple crates to ensure bitvec 0.22.3 is being used and avoid package conflicts
* Add documentation to zebra-chain::sapling to indicate that ZIP-216 rules are enforced by jubjub

* Impl subtle::ConstantTimeEq for orchard SpendingKey, use that in Eq/PartialEq
* Use constant time comparisons for secret key data where applicable
This also makes Clippy happier so that we aren't creating types just to compare.
* Fix clippy::cmp_owned for orchard::keys Eq/PartialEq
By impl'ing ConstantTimeEq for those types where leaks of the value
would compromise access or privacy.
* Make clippy::cmp_owned happy for some sapling::keys
* validate sapling v5 tx
* Make itertools dependency optional
We only need itertools when the `proptest-impl` feature is enabled.
* Check if V4 and V5 coinbase transactions contain PrevOut transparent inputs
This is a bugfix on V4 transaction validation. The PrevOut consensus
rule was not explicitly stated in the Zcash spec until April 2021.
(But it was implied by Bitcoin, and partially implemented by Zebra.)
Also do the shielded sapling input check for V5 transactions.
* Add spec and orchard TODOs to has_inputs_and_outputs
Also make the variable names match the spec.
* Sort transaction functions to match v5 data order
* Simplify transaction input and output checks
Move counts or iterators into `Transaction` methods, so we can remove
duplicate code, and make the consensus rule logic clearer.
* Update sapling_balances_match for Transaction v5
- Quote from the spec
- Explain why the function is redunant for v5
- Rename the function so it's clear that it is sapling-specific
