signature: use &mut impl CryptoRngCore RNG arguments#1147
Merged
Conversation
`rand_core` v0.6.4 added an auto-impl'd `CryptoRngCore` marker trait for types which impl `CryptoRng + RngCore` which is slightly more convenient and less verbose. This commit changes to using `&mut impl CryptoRngCore` as proposed in #1087. This hopefully strikes a balance between least surprise and minimal required syntax, namely &mut references are reusable and don't require knowledge of the blanket impl of `RngCore` for `&mut R: RngCore`

I opened #1148 which spells out the rationale for this type signature a bit more and can hopefully serve as a place to discuss if we should switch to this across the other trait crates (or if not this, then discussing what it should be). |

In #1147, other usages of a CSRNG were changed to use `&mut impl CryptoRngCore`. However, `RandomizedPrehashSigner` was not updated accordingly. This commit updates it as well.

As discussed in RustCrypto/traits#1148, this uses `&mut impl CryptoRngCore` as the API for passing CSRNGs. This removes the need for a generic parameter in the type signature while also keeping syntax to a minimum. The traits in `signature` v2.0.0-pre.2 switched to these APIs. See RustCrypto/traits#1147.
