Upgrade all crates to the 2024 edition and bump MSRV to 1.85

[baloo]

This currently excludes:

• dsa because it's getting ported over to crypto-bigint

This depends on:

• elliptic-curve: bump rand_core to 0.9.0 traits#1751
• elliptic-curve: relax Sized requirements on Rng traits#1767
• Bump rand_core from 0.6.4 to 0.9.0 crypto-bigint#762
• Bump version to v0.7.0-pre crypto-bigint#765
• Bump rand to 0.9 zkcrypto/ff#122
• Bump to rust-random 0.9 zkcrypto/group#56
• Upgrade all crates to the 2024 edition and bump MSRV to 1.85 hashes#652
• Upgrade all crates to the 2024 edition and bump MSRV to 1.85 MACs#178

Opinion about RandomizedSignerMut signature?

[baloo]

We kind of eat the error here. This might be a bad idea.

I wish we could do Error::from_source instead, but that would require the RandomizedSignerMut to change its signature to something like:

fn try_sign_with_rng<E: core:error::Error, R: TryCryptoRng<Error = E>>(
        &mut self,
        rng: &mut R,
        msg: &[u8],
    ) -> Result<Signature<Mode>, Error> {
``
Not sure.

[tarcieri]

We can potentially consider something like that

similar situation here.

@baloo can you rebase?

[erik-3milabs]

Would it be possible to include new elliptic-curve and ecdsa pre-releases with this PR? 😄

Currently, ecdsa@0.17.0-pre.9 and crypto-bigint@0.6.0 do not work together, because:

• elliptic-curve@0.14.0-rc.1 (on which ecdsa depends) pins serdect=0.3.0-rc.0, while
• crypto-bigint@0.6.0 requires ^0.3.

elliptic-curve has already been updated to use 0.3.0; it just needs a new release for these packages to work together again.

I might be mistaken, but all I think needs to happen is:

• release elliptic-curve@0.14.0-rc.2
• have ecdsa depend on this new release, and
• release ecdsa@0.17.0-pre.9.

If this is not the right place and/or time, I'm happy to create a separate issue for it :)

@erik-3milabs we generally do releases in separate PRs to keep ones like this focused

[baloo]

Just to mitigate expectations, I don't know if we'll be able to release elliptic-curve until the situation of group and ff support of rand_core 0.9 is sorted out. (RustCrypto/traits#1751 (comment))

@erik-3milabs we generally do releases in separate PRs to keep ones like this focused

In that case, would there be a point in raising an issue for this?

[tarcieri]

Sure, please open a separate issue
