* Send `Response::Nil` instead of sending empty `Message`s
This matches `zcashd`'s behaviour more closely.
In most cases, the network layer filters these out already.
But this change makes the the inbound service code clearer.
* revert changes made to `AdvertiseTransactionIds` and `PushTransaction`
* remove newline

* Remove return of redundant vector length
An attempt to improve readability a bit by not returning a tuple with a
value that can be obtained from a single return type.
* Refactor `unmined_transactions_in_blocks`
Use a more functional style to try to make it a bit clearer.
* Use ranges in `unmined_transactions_in_blocks`
Allow a finer control over the block range to extract the transactions
from.
* Refactor mempool test code to improve clarity
It was previously not clear that only the first genesis transaction was
being used. The remaining transactions in the genesis block were
discarded and then readded later.
* Replace `oneshot` with `call`
Remove a redundant internal `ready_and` call.
* Return an `impl Iterator` instead of a `Vec<_>`
Remove unnecessary deserializations and heap allocations.
* Refactor `mempool_storage_basic_for_network` test
Make the separation between the transactions expected to be in the
mempool and those expected to be rejected clearer.
* Replace `Iterator` with `DoubleEndedIterator`
Allow getting the last transaction more easily.

* Use `MockService` in inbound test
Refactor the `mempool_requsets_for_transactions` test so that it uses a
`MockService` instead of the `mock_peer_set` function.
* Use `MockService` in the basic mempool test
Refactor the `mempool_service_basic` test so that it uses a
`MockService` instead of the `mock_peer_set` helper function.
* Remove the `mock_peer_set` helper function
It is not used anymore, since the usages were replaced with
`MockService`s.
* add tests for mempool inbound requests
* Use MockService for transaction verifier
* Refactor creation of mock `peer_set`
Use the same style as the mock transaction verifier.
* Derive `Eq` for `zebra_network::Request`
Make it easy to use the `MockService::expect_request` method.
* Return mocked peer set service from `setup`
Allow it to be used to respond to requests.
* Add bindings for the transaction used for testing
Allow them to be moved into futures later.
* Respond to transaction download request
Make sure that the test transaction appears to the mempool as if it had
been downloaded by the peer set service.
* Assert that no unexpected requests were received
Check that the mempool doesn't send unexpected requests to the peer set
service.
* add tests for mempool inbound requests
* Use MockService for transaction verifier
* add missing `expect_no_requests` to `mempool_advertise_transaction_ids` test

* Allow deliberate instances of the new nightly clippy::derivable_impls lint
We want our config defaults to be explicit.
Not so sure about the application defaults, but they also contain a config.
* Also allow unknown lint names
Stable doesn't know about this lint, but nightly does.
* Implement initial service mocking helpers
Adds a [`MockService`] type, which can be configured and built for usage
in unit tests or proptests. The mocked service can then be used to
intercept requests and respond indivdiually to them.
* Use `MockService in the `mempool::Crawler` test
Refactor it to remove the helper mock function, and use the new
`MockService` helper type.
* Use `MockService` in `CandidateSet` test vectors
Refactor to remove the manual mocking of the peer set service.
* Panic if a response is not sent by `MockService`
Change the current semantics to require all `MockService` usages to
respond to every intercepted request.
A `must_use` attribute was added to the `ResponseSender` so that the
compiler can warn when this doesn't happen.
* Allow generic error types in `MockService`
Replace the hard-coded `BoxError` as the `Service`'s error type with a
generic type parameter. This allows mocking services in locations that
require specific error types.
* Add a `ResponseSender::request` getter
Allow inspecting the request again before responding, and using
information from the request in the response.

Using `&mut self` as the receiver in the method signatures allows Rust
to infer that the type is properly `Sync`, and therefore `Send`. This
allows removing the `Mutex` work-around.
* Decide if Zebra is at the chain tip
* Avoid division by zero
* Try increasing EVENT_TIMEOUT
* Increase MAX_TEST_EXECUTION
* Implement basic tests

* reply to `Request::MempoolTransactionIds`
* remove boilerplate
* get storage from mempool with a method
* change panic message
* try fix for mac
* use normal init instead of init_tests for state service
* newline
* rustfmt
* fix test build
* Use `TipAction::Reset` for initialization and out-of-order blocks
Needs tests for:
- cloning a `ChainTipChange` resets the cloned instance
- skipped updates reset the cloned instance
- changing forks resets the cloned instance
* Use `TipAction::Reset` for network upgrade activation blocks
* Use an `if` expression

* Rename ChainTipReceiver to CurrentChainTip
`fastmod ChainTipReceiver CurrentChainTip zebra*`
* Update chain tip documentation and variable names
* Basic chain tip change implementation, without resets
Also includes the following name changes:
```
fastmod CurrentChainTip LatestChainTip zebra*
fastmod chain_tip_receiver latest_chain_tip zebra*
```
* Clarify the difference between `LatestChainTip` and `ChainTipChange`
We don't check the authorizing data hash until checkpoint blocks reach the state.
So signatures, proofs, or scripts could be different,
even if the block hash is the same.

* Store a `SyncStatus` handle in the `Crawler`
The helper type will make it easier to determine if the crawler is
enabled or not.
* Pause crawler if mempool is disabled
Implement waiting until the mempool becomes enabled, so that the crawler
does not run while the mempool is disabled.
If the `MempoolStatus` helper is unable to determine if the mempool is
enabled, stop the crawler task entirely.
* Update test to consider when crawler is paused
Change the mempool crawler test so that it's a proptest that tests
different chain sync. lengths. This leads to different scenarios with
the crawler pausing and resuming.
