* Rename type parameter to be more explicit
Replace the single letter with a proper name.
* Remove imports for `Request` and `Response`
The type names will conflict with the ones for the mempool service.
* Attach `Mempool` service to the `Crawler`
Add a field to the `Crawler` type to store a way to access the `Mempool`
service.
* Forward crawled transactions to downloader
The crawled transactions are now sent to the transaction downloader and
verifier, to be included in the mempool.
* Derive `Eq` and `PartialEq` for `mempool::Request`
Make it simpler to use the `MockService::expect_request` method.
* Test if crawled transactions are downloaded
Create some dummy crawled transactions, and let the crawler discover
them. Then check if they are forwarded to the mempool to be downloaded
and verified.
* Don't send empty transaction ID list to downloader
Ignore response from peers that don't provide any crawled transactions.
* Log errors when forwarding crawled transaction IDs
Calling the Mempool service should not fail, so if an error happens it
should be visible. However, errors when downloading individual
transactions can happen from time to time, so there's no need for them
to be very visible.
* Document existing `mempool::Crawler` test
Provide some depth as to what the test expect from the crawler's
behavior.
* Refactor to create `setup_crawler` helper function
Make it easier to reuse the common test setup code.
* Simplify code to expect requests
Now that `zebra_network::Request` implement `Eq`, the call can be
simplified into `expect_request`.
* Refactor to create `respond_with_transaction_ids`
A helper function that checks for a network crawl request and responds
with the given list of crawled transaction IDs.
* Refactor to create `crawler_iterator` helper
A function to intercept and respond to the fanned-out requests sent
during a single crawl iteration.
* Refactor to create `respond_to_queue_request`
Reduce the repeated code necessary to intercept and reply to a request
for queuing transactions to be downloaded.
* Add `respond_to_queue_request_with_error` helper
Intercepts a mempool request to queue transactions to be downloaded, and
responds with an error, simulating an internal problem in the mempool
service implementation.
* Derive `Arbitrary` for `NetworkUpgrade`
This is required for deriving `Arbitrary` for some error types.
* Derive `Arbitrary` for `TransactionError`
Allow random transaction errors to be generated for property tests.
* Derive `Arbitrary` for `MempoolError`
Allow random Mempool errors to be generated for property tests.
* Test if errors don't stop the mempool crawler
The crawler should be robust enough to continue operating even if the
mempool service fails to download transactions or even fails to handle
requests to enqueue transactions.
* Reduce the log level for download errors
They should happen regularly, so there's no need to have them with a
high visibility level.

* Stop crawler if service stops
If `Mempool::poll_ready` returns an error, it's because the mempool
service has stopped and can't handle any requests, so the crawler should
stop as well.

* Minimal recent sync lengths implementation
Also includes metrics and logging, to make diagnosing bugs easier.
* Add logging to check what happens when Zebra reaches the chain tip
* Add tests for recent sync lengths
- initially empty
- pruned to correct length
- newest entries go first
* Drop a redundant `/` from a Cargo.lock URL
This seems to be a nightly or beta Rust change,
but hopefully stable just accepts it.
* Use metrics histograms to avoid overwriting values
* Add detailed syncer monitoring dashboard
* Increase the recent sync length to 4
This length makes it easier to distinguish between temporary and
sustained errors/syncs.

* Reject duplicate sprout nullifiers in the state
* Improve docs and error messages
* Clarify "must be present" assert logs
* Move nullifier checks to their own module
Also:
* make non-finalized nullifier checks and errors generic over
sprout, sapling, and orchard
* create and update module and function documentation
* Fix a block type name in docs
* Move state assertions or skip them during tests
These changes enable state testing, while still asserting in production.
* Add sprout duplicate nullifier tests
* Improve comments
* Set value balance to 0 to pass future chain value pool checks
* Test finalized state in sprout nullifier accept test
* Replace assert with expect
* Improve assertion messages
* 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
* Add a `zebra_test::RUNTIME` shared runtime
Create a lazily instantiated Tokio runtime that can be shared by tests.
* Split tests that require a shared runtime
Split two tests that were previously in one because of the need to share
a single Tokio runtime. With the `zebra_test::RUNTIME`, they can now
share the runtime without having to be a single test.
* Refactor to create `verify_sprout_shielded_data`
Move the join split verification code into a new
`verify_sprout_shielded_data` helper method that returns an
`AsyncChecks` set.
* Test if signed V4 tx. join splits are accepted
Create a fake V4 transaction with a dummy join split, and sign it
appropriately. Check if the transaction verifier accepts the
transaction.
* Test if unsigned V4 tx. joinsplit data is rejected
Create a fake V4 transaction with a dummy join split. Do NOT sign this
transaction's join split data, and check that the verifier rejects the
transaction.
* Join tests to share Tokio runtime
Otherwise one of the tests might fail incorrectly because of a
limitation in the test environment. `Batch` services spawn a task in the
Tokio runtime, but separate tests can have separate runtimes, so sharing
a `Batch` service can lead to the worker task only being available for
one of the tests.
* 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

* Gossip dynamically allocated listener ports to peers
Previously, Zebra would either gossip port `0`, which is invalid, or skip
gossiping its own dynamically allocated listener port.
* Improve "no configured peers" warning
And downgrade from error to warning, because inbound-only nodes are a
valid use case.
* Move random_known_port to zebra-test
* Add tests for dynamic local listener ports and the AddressBook

- Add a custom semver match for `zebrad` versions
- Prefer "line contains string" matches, so tests ignore minor changes
- Escape regex meta-characters when a literal string match is intended
- Rename test functions so they are more precise
- Rewrite match internals to remove duplicate code and enable custom matches
- Document match functions

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

lexical-core 0.7.4 is incompatible with rustc nightly >= ~2021-03-24,
see https://github.com/rust-lang/rust/issues/81654
While we're waiting for zcash_script, rocksdb, and their dependencies to
upgrade, patch lexical-core to 0.7.5 in the zebra workspace.
* Move the preallocate tests into their own files
And move the MetaAddr proptest into its own file.
Also do some minor formatting and cleanups.

* 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

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)
