446597bd3c Remove the reset() function from hash functions 
Justification:
- reset() is unnecessary; states that have to be reused can be copied
- reset() is error-prone. Copying a previous state prevents forgetting
  struct members.
- reset() forces implementation to store sensitive data (key, initial state)
  in memory even when they are not needed.
- reset() is confusing as it has a different meaning elsewhere in Zig.

6f9ea9eaef Breaking: sort std/crypto functions into categories 
Instead of having all primitives and constructions share the same namespace,
they are now organized by category and function family.

Types within the same category are expected to share the exact same API.

795033c35f std/crypto: XChaCha20, detached modes and standard AEAD API 
* Factor redundant code in std/crypto/chacha20

* Add support for XChaCha20, and the XChaCha20-Poly1305 construction.

XChaCha20 is a 24-byte version of ChaCha20, is widely implemented
and is on the standards track:
https://tools.ietf.org/html/draft-irtf-cfrg-xchacha-03

* Add support for encryption/decryption with the authentication tag
detached from the ciphertext

* Add wrappers with an API similar to the Gimli AEAD type, so that
we can use and benchmark AEADs with a common API.

5f9953f41f Remove mem.timingSafeEqual() for now

signature verification.

3f0d80f25e Improve curve25519-based crypto 
This is a rewrite of the x25519 code, that generalizes support for
common primitives based on the same finite field.

- Low-level operations can now be performed over the curve25519 and
edwards25519 curves, as well as the ristretto255 group.
- Ed25519 signatures have been implemented.
- X25519 is now about twice as fast.
- mem.timingSafeEqual() has been added for constant-time comparison.

Domains have been clearly separated, making it easier to later add
platform-specific implementations.
