We would like to do away with the `GeneralHash` trait. Currently we
bound `Hmac` and `HmacEngine` on it but this is unnecessary now that we
have added `HashEngine::finalize` and `HashEngine::Hash`.
Bound the `HmacEngine` on `HashEngine` (which has an associated `Hash`
type returned by `finilalize`).
Bound `Hmac` type on `T::Hash` where `T` is `HashEngine`.
Includes some minor shortening of local variable names around hmac
engine usage.
Note this means that `Hmac` no longer implements `GeneralHash`.
da8b85ed7c Implement Debug for Hkdf (Tobin C. Harding)
85652359e8 hashes: Derive Copy and Clone for Hkdf (Tobin C. Harding)
Pull request description:
Currently the `Hkdf` type does not derive any traits.
Derive `Copy` and `Clone` and implement `Debug` based on secret obfuscation algo in `rust-secp` (in the `secret` module).

Currently the `Hkdf` type does not derive any traits.
We would like to derive the common set of traits but there are a bunch
reasons we can't;
- Don't want to leak secrets in `Debug`.
- Don't want to enable timing attacks with Eq/Ord and friends.
For now just derive `Copy` and `Clone`. We will then implement `Debug`
manually.
In preparation for removing a bunch of macros move all the modules to
`<mod>/mod.rs`.
Do so by running the following shell:
```bash
for mod in hash160 ripemd160 sha1 sha256 sha256d sha256t \
sha384 sha512 sha512_256 siphash24 hkdf hmac; do
mkdir $mod
mv "$mod.rs" "$mod/mod.rs"
done
```
Internal change only.
