Test consensus-critical `Amount` deserialization (#2487) 
* 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.

Refactor validation of Sapling shielded data in `transaction::Verifier` (#2419) 
* 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.

By impl'ing ConstantTimeEq for those types where leaks of the value
would compromise access or privacy.

Add V5 transparent and sapling to transaction::check, add missing coinbase PrevOut check (#2070) 
* 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

Ed25519 async batch verification for JoinSplit signatures (#1952) 
* Ed25519 async batch verification for JoinSplit signatures

We've been verifying JoinSplitSigs one-by-one pre-ZIP-215. Now as we're post-ZIP-215,
we can take advantage of the batch math to validate this signatures.

I would have pumped all the joinsplits in our MAINNET_BLOCKS test vectors but these
signatures are over the sighash, which needs the NU code to compute, and once we're
doing all that set up, we're basically doing transaction validation, so.

Resolves #1944

* Repoint to latest ed25519-zebra commit with note to point at 3.0 when released

Bump versions for v1.0.0-alpha.5 (#1932) 
Zebra's latest alpha checkpoints on Canopy activation, continues our work on NU5, and fixes a security issue.

Some notable changes include:

## Added
- Log address book metrics when PeerSet or CandidateSet don't have many peers (#1906)
- Document test coverage workflow (#1919)
- Add a final job to CI, so we can easily require all the CI jobs to pass (#1927)

## Changed
- Zebra has moved its mandatory checkpoint from Sapling to Canopy (#1898, #1926)
  - This is a breaking change for users that depend on the exact height of the mandatory checkpoint.

## Fixed
- tower-batch: wake waiting workers on close to avoid hangs (#1908)
- Assert that pre-Canopy blocks use checkpointing (#1909)
- Fix CI disk space usage by disabling incremental compilation in coverage builds (#1923)

## Security
- Stop relying on unchecked length fields when preallocating vectors (#1925)

Previously we set the crate versions to 3.x, so that the major version was
aligned with the NU version.  But we want to be able to make API changes

Henry de Valence 4aa00ad216 Align crate versions and user-agent with NU numbers. 
We had a brief discussion on discord and it seemed like we had consensus on the
following versioning policy:

* zebrad: match major version to NU version, so we will start by releasing
  zebrad 3.0.0;

* zebra-* libraries: start by matching zebrad's version, then increment major
  versions of each library as we need to make breaking changes (potentially
  faster than the zebrad version, always respecting semver but making no
  guarantees about the longevity of major releases).

This commit sets all of the crate versions to 3.0.0-alpha.0 -- the -alpha.0
marks it as a prerelease not subject to perfect adherence to compatibility
guarantees.
