* Cleanup module docs and imports for sapling::arbitrary

* Upgrade dependencies shared with zcashd 5.5.0

```sh
cargo upgrade --workspace << EOF
bellman
bls12_381
group
halo2
halo2_proofs
jubjub
orchard
redjubjub
zcash_address
zcash_note_encryption
zcash_primitives

EOF
```

* Replace orchard::from_bytes_wide() with ff::from_uniform_bytes()

* Revert "disable test (#6285)" to re-enable verify_generated_halo2_proofs

This reverts commit 4d4accc0b9.

fix: Inconsistent Docs for Downloading ZKP Params (#6464)
* Use `ATTEMPTS` instead of `RETRIES`

This commit also removes the prefix `retry_` from the function names
that download the parameters. The reason for removing it was that I
consider the retries implicit, and the primary objective of the
functions is to download the params, not retry to download them.

* Docs cosmetics

* Apply suggestions from code review

Co-authored-by: Arya <aryasolhi@gmail.com>

* Change `ATTEMPTS` back to `RETRIES`

Download Zcash Sapling parameters and load them from cached files (#3057)
* Replace Zcash parameters crates with pre-downloaded local parameter files

* Download Zcash parameters using the `zcashd` script in CI and Docker

* Add a zcash_proofs dependency to zebra-consensus

* Download Sapling parameters using zcash_proofs, rather than fetch-params.sh

* Add a new `zebrad download` subcommand

This command isn't required for nomrmal usage.
But it's useful when testing, or launching multiple Zebra instances.

* Use `zebrad download` in CI to pre-download parameters

* Log a helpful hint if downloading fails

* Allow some duplicate dependencies currently hidden by orchard

* Spawn a separate task to download Groth16 parameters

* Run the parameter download with code coverage

This avoids re-compining Zebra with and without coverage.

* Update Cargo.lock after rebase

* Try to pass `download` as an argument to `zebrad` in coverage CI

* Fix copy and paste comment typos

* Add path and download examples, like zcash_proofs

* Download params in CI just like zcash_proofs does

* Delete a redundant build step

* Implement graceful shutdown for zebrad start

* Send coverage summary to /dev/null when getting the params path

* Use the correct parameters path and download commands in CI

* Explain pre-downloads

* Avoid calling params_folder twice

* Rename parameter types and methods for consistency

```sh
fastmod SaplingParams SaplingParameters zebra*
fastmod Groth16Params Groth16Parameters zebra*
fastmod PARAMS GROTH16_PARAMETERS zebra*
fastmod params_folder directory zebra*
```

And a manual variable name tweak.

Update to Tokio 1.13.0 (#2994)
* 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.

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

Jane Lusby 0ac259430a Implement Async Batch verification API for groth16
This PR is the first step in getting a groth16 proving system fully
integrated with the rest of zebra. This PR implements the initial async
API, but none of the actual batching logic necessary for our eventual
verifier design.

Once the batch verification API from bellman has been implemented we
will need to swap out the "Batch" type defined in this crate with the
new `batch::Verifier` defined in bellman.

Henry de Valence add94c1c45 deps: move to tokio 0.3, tower 0.4
This change is mostly mechanical, with the exception of the changes to the
`tower-batch` middleware.  This middleware was adapted from `tower::buffer`,
and the `tower::buffer` code was changed to implement its own bounded queue,
because Tokio 0.3 removed the `mpsc::Sender::poll_send` method.  See

ddc64e8d4d

for more context on the Tower changes.  To match Tower as closely as possible
in order to be able to upstream `tower-batch`, those changes are copied from
`tower::Buffer` to `tower-batch`.

Henry de Valence 6dd7318d3b deps: use Tower 0.4 from git instead of 0.3.1.
This addresses at least three pain points:

- we were affected by bugs that were already fixed in git, but not in
  the released crate;
- we can use service combinators to transform requests and responses;
- we can use the hedge middleware.

The version in git is still marked as 0.3.1 but these changes will be
part of tower 0.4: https://github.com/tower-rs/tower/issues/431

Henry de Valence 8d4f154c9f consensus: move redjubjub to new primitives module
This will let it sit alongside a groth16 verifier.
