* Update `tower` to version `0.4.9`
Update to latest version to add support for Tokio version 1.
* Replace usage of `ServiceExt::ready_and`
It was deprecated in favor of `ServiceExt::ready`.
* Update Tokio dependency to version `1.13.0`
This will break the build because the code isn't ready for the update,
but future commits will fix the issues.
* Replace import of `tokio::stream::StreamExt`
Use `futures::stream::StreamExt` instead, because newer versions of
Tokio don't have the `stream` feature.
* Use `IntervalStream` in `zebra-network`
In newer versions of Tokio `Interval` doesn't implement `Stream`, so the
wrapper types from `tokio-stream` have to be used instead.
* Use `IntervalStream` in `inventory_registry`
In newer versions of Tokio the `Interval` type doesn't implement
`Stream`, so `tokio_stream::wrappers::IntervalStream` has to be used
instead.
* Use `BroadcastStream` in `inventory_registry`
In newer versions of Tokio `broadcast::Receiver` doesn't implement
`Stream`, so `tokio_stream::wrappers::BroadcastStream` instead. This
also requires changing the error type that is used.
* Handle `Semaphore::acquire` error in `tower-batch`
Newer versions of Tokio can return an error if the semaphore is closed.
This shouldn't happen in `tower-batch` because the semaphore is never
closed.
* Handle `Semaphore::acquire` error in `zebrad` test
On newer versions of Tokio `Semaphore::acquire` can return an error if
the semaphore is closed. This shouldn't happen in the test because the
semaphore is never closed.
* Update some `zebra-network` dependencies
Use versions compatible with Tokio version 1.
* Upgrade Hyper to version 0.14
Use a version that supports Tokio version 1.
* Update `metrics` dependency to version 0.17
And also update the `metrics-exporter-prometheus` to version 0.6.1.
These updates are to make sure Tokio 1 is supported.
* Use `f64` as the histogram data type
`u64` isn't supported as the histogram data type in newer versions of
`metrics`.
* Update the initialization of the metrics component
Make it compatible with the new version of `metrics`.
* Simplify build version counter
Remove all constants and use the new `metrics::incement_counter!` macro.
* Change metrics output line to match on
The snapshot string isn't included in the newer version of
`metrics-exporter-prometheus`.
* Update `sentry` to version 0.23.0
Use a version compatible with Tokio version 1.
* Remove usage of `TracingIntegration`
This seems to not be available from `sentry-tracing` anymore, so it
needs to be replaced.
* Add sentry layer to tracing initialization
This seems like the replacement for `TracingIntegration`.
* Remove unnecessary conversion
Suggested by a Clippy lint.
* Update Cargo lock file
Apply all of the updates to dependencies.
* Ban duplicate tokio dependencies
Also ban git sources for tokio dependencies.
* Stop allowing sentry-tracing git repository in `deny.toml`
* Allow remaining duplicates after the tokio upgrade
* Use C: drive for CI build output on Windows
GitHub Actions uses a Windows image with two disk drives, and the
default D: drive is smaller than the C: drive. Zebra currently uses a
lot of space to build, so it has to use the C: drive to avoid CI build
failures because of insufficient space.

* Don't expect `services` to be available
Avoid a panic by using the compiler to help enforce the handling of the
case correctly.
* Panic if received gossiped address has no services
All received gossiped addresses have services. The only addresses that
don't have services configured are the initial seed addresses.

* Avoid spurious test failures on busy machines
* Revert "Avoid spurious test failures on busy machines"
This reverts commit 4430a48ef3.
* Increase request delay for mock network service
This is necessary because some tests were having timeouts when running
on macOS for the CI. This meant that it took longer than expected for
the subject under test to end up sending the network request.

* Reorder imports to follow convention
Place the imports from `std` at the top.
* Add transaction errors for double spends
Add a variant for each pool. They represent a double spend inside a
transaction.
* Add `check::spend_conflicts` implementation
Checks if a transaction has spend conflicts, i.e., if a transaction
spends a UTXO more than once or if it reveals a nullifier more than
once.
* Reject transactions with internal spend conflicts
The transaction verifier should reject transactions that spend the same
transparent UTXO or that reveal the same nullifier.
* Add transparent spend consensus rule
Add it to the documentation to help with understanding and auditing it.
Co-authored-by: teor <teor@riseup.net>
* Use different nullifiers by default
Don't use the same nullifier twice when mocking a
`sprout::JoinSplitData` because it will lead to an invalid transaction.
* Test transactions with repeated spend outpoints
Since that represents a spend conflict, they should be rejected.
* Test duplicate nullifiers in joinsplit
Check if a mock transaction with a joinsplit that reveals the same
nullifier twice is rejected.
* Test duplicate nullifiers across joinsplits
Check if a duplicate nullifier in two different joinsplits in the same
transaction is rejected.
* Test V4 transaction with duplicate Sapling spend
Check if a V4 transaction that has a duplicate Sapling spend is
rejected.
* Test V5 transaction with duplicate Sapling spend
Check if a V5 transaction that has a duplicate Sapling spend is
rejected.
* Test V5 transaction with duplicate Orchard actions
Check if a V5 transaction that has duplicate Orchard actions is rejected
by the transaction verifier.

* Wrap `Sleep` timer in a `Pin<Box<_>>`
The `Sleep` type doesn't implement `Unpin` in newer versions of Tokio.
* Wrap `Sleep` type in a `Pin<Box<_>>`
In newer Tokio versions the `Sleep` type doesn't implement `Unpin`, so
it needs to be manually pinned.
* Try simulating a chain growth
* Adjust the transaction expiry height
The mempool evicts expired transactions. When working with mocked data,
appending a new block typically clears the mempool because transactions become
expired. For this reason, the expiry height of each transactions is adjusted so
that it is greater than the new chain tip's height.
* Refactor the code so that it works with `VerifiedUnminedTx`

Newer versions of Tokio panic if `tokio::time::pause()` is called from a
multi-thread executor, and `#[tokio::test]` defaults to a single thread
runtime, so it makes sense to always use a single thread runtime in all
tests.
This matches the settings for `sync_large_checkpoints_mainnet`.
Also reduce the number of blocks synced to reduce network load.
Co-authored-by: Alfredo Garcia <oxarbitrage@gmail.com>
In newer Tokio versions the `Sleep` type doesn't implement `Unpin`, so
it's a little more complicated to use it. In this case it was easier to
refactor the code to not store the `Sleep` type instead of wrapping it
in a `Pin` type.

* Create a `NowOrLater` helper type
A replacement for `FutureExt::now_or_never` that ensures that the task
is scheduled for waking up later when the inner future is ready.
* Use `NowOrLater` to fix possible delay bug
Previous usage of `now_or_never` meant that the underlying task wasn't
being scheduled to awake when the `Downloads` stream produced a new
item. Using `NowOrLater` instead fixes that issue.
