rustfmt: Use now config option fn_params_layout
`rustfmt` warns:

 Warning: the `fn_args_layout` option is deprecated. Use
 `fn_params_layout`. instead

As suggested, use now config option `fn_params_layout`.

Pull request description:

  I was reading the docs for `normalize_s` and got confused what the point was - it says that libsecp "will only accept" signatures that are normalized, which led me to believe it would refuse to deserialize such signatures. This is untrue, it only refuses to *validate* such signatures.

  As per ecosystem wide change, bump the MSRV of both crates to 1.48

  Patch 1 is a typo fix to the changelog, I don't see changelogs cached on crates.io in any way so this fix should be able to quietly go in.

  Note before this is applied there is no mention of the MSRV in secp256k1-sys, was that intentional? If not, with this applied, we have a mention in the readme.

  CI needs some more fixes (wasm job) but because patching CI often leads to me doing 300 pushes I'm leaving it to a separate PR.

secp256k1-sys: Remove custom implementations of Eq, Ord and friends
Note: Only effects code when fuzzing is enabled, as such does not
include a mention in the changelog.

Now that we have Rust 1.48 as the MSRV we no longer need the custom
implementations of `PartialEq`, `Eq`, `PartialOrd`, `Ord`, and `Hash`.
We can just let users of the `impl_array_newtype` macro derive these
traits if they want them.

Remove the custom implementations and add derives to our two users of
the macro.

Pull request description:

  This is a proposed strategy for maintaining tested lockfiles in the rust-bitcoin ecosystem. The idea is that we would have both a "minimal" and a "latest" lockfile, and in both cases we have trusted crev reviews for all dependencies (this is not implemented here, I'd like to start by committing the lockfiles so we can agree what to review).

  Periodically we can update the "latest" one to reflect new versions of deps that we've gotten around to reviewing.

  I have local nix build scripts that are able to test every commit of proposed PRs against both lockfiles. In CI it is probably reasonable to at least do `cargo test --locked --all-features` with both of them, to make sure that the tests at least pass on each PR with them.

  Thoughts?

rewrite ./vendor-libsecp.sh
This rewrite:
   * Fixes some shellcheck issues (bad quoting, use of | instead of ||
     near the beginning of the file)
   * Automatically computes the version prefix, depend directory, etc.,
     and provides instructions to override this with env vars if the
     user really wants to do this.
   * Detects when it would be destructive and refuses to run unless
     passed the -f flag, rather than prompting the user for a yes/no
   * Adds the capability to use cp rather than git clone, which I need
     to run this from within Nix.
   * Whitelists CHANGELOG.md which shouldn't get substituted.

tests: replace cbor with more-recently-deprecated serde_cbor
The `cbor` crate has been unmaintained for several years, and depends on
the ancient `rustc_serialize` crate which (a) doesn't build on WASM, and
(b) doesn't build when we use a minimal-dep Cargo.lock. (The latter is
because cbor specifies rustc_serialize 0.3.0 when it should specify 0.3.1,
but there is nothing we can do to fix that when cbor is unmaintained.)

This changes a hardcoded value in a regression test, but it's because
we're replacing the serialization engine rather than changing our code,
so this is not actually a change.

- Rename symbols to from `0_8_0` -> `0_8_1`, done mechanically (search

- Add changes log notes (includes changelog entry for 0.8.0)
- Bump `secp256k1-sys` crate version 0.8.0 -> 0.8.1, justified because

Merge rust-bitcoin/rust-secp256k1#582: implement `insecure-erase` feature (was: `Zeroize`)
8fffbeab13 implement "non_secure_erase" methods (kwantam)

Pull request description:

  This PR adds [`Zeroize`](https://docs.rs/zeroize) derivations for the following structs:

  - `SecretKey`
  - `KeyPair`
  - `SharedSecret`
  - `Scalar`
  - `DisplaySecret`

  This is *only* a Zeroize impl, and does not make Zeroize happen automatically on drop (doing that would be a breaking change because it would preclude deriving `Copy`). But this is still useful, because it allows downstream libraries to implement `ZeroizeOnDrop` for structs that contain such secrets and/or simply to use the `Zeroizing` container struct.

  Because these new impls are never invoked automatically, performance impact should be zero. Safety-wise, the `Zeroize` library appears to be widely used in cryptographic code. For example, Supranational's [blst](https://github.com/supranational/blst) Rust bindings use it, and in turn are used in one of the most popular eth2 validator implementations.

  Thanks for maintaining a really great library!

implement "non_secure_erase" methods
This PR implements a `non_secure_erase()` method on SecretKey,
KeyPair, SharedSecret, Scalar, and DisplaySecret. The purpose
of this method is to (attempt to) overwrite secret data with
valid default values. This method can be used by libraries
to implement Zeroize on structs containing secret values.

`non_secure_erase()` attempts to avoid being optimized away or
reordered using the same mechanism as the zeroize crate: first,
using `std::ptr::write_volatile` (which will not be optimized
away) to overwrite the memory, then using a memory fence to
prevent subtle issues due to load or store reordering.

Note, however, that this method is *very unlikely* to do anything
useful on its own. Effective use involves carefully placing these
values inside non-Copy structs and pinning those structs in place.
See the [`zeroize`](https://docs.rs/zeroize) documentation for tips
and tricks, and for further discussion.

  Currently we have a wildcard on safety requirements, saying more or less "plus a bunch of other stuff we don't mention". This is not helpful.

  Attempt to fully describe the safety requirements of creating a context from a raw context (all, signing only, and verification only).

  ## Note

  This is best effort only, will require some thought to review. To do this I read https://doc.rust-lang.org/reference/behavior-considered-undefined.html and then I flicked through `depend/secp256k1/src/secp256k1.c` and `util.h` to look for things that could cause things in the linked to list of UB.

Merge rust-bitcoin/rust-secp256k1#578: Implement `Debug` trait for `Scalar` type
8ed8cac2fe Implement `Debug` trait for `Scalar` type. (Arik Sosman)

Pull request description:

  Currently, `Scalar` types do not implement the `Debug` trait, whereas most other types in the library do. Besides that being an upstream requirement for us, I believe it would also be quite useful for users of that type.

  Also implements the `Index` traits for `Scalar`.

Tobin C. Harding e705bcffb5 Fully describe safety requirements
Currently we have a wildcard on safety requirements, saying more or less
"plus a bunch of other stuff we don't mention". This is not helpful.

Attempt to fully describe the safety requirements of creating a context
from a raw context (all, signing only, and verification only).

Fix: #544

d1184156c6 Fix CI (Tobin C. Harding)

Pull request description:

  Currently CI is broken because we use the latest version of `rustfmt` and `clippy` in CI. We can resolve the `rustfmt` issue permanently by removing the `required_version` config option. We also need to fix the latest clippy warnings.

  Done as a single patch so that all patches pass CI.

Pull request description:

  We do not need to use the `hex` module from `bitcoin_hashes` to encode into hex, we have a function in this library.

Merge rust-bitcoin/rust-secp256k1#572: add redundant features for cargo 1.41 bug
fe828d040d add redundant features for cargo 1.41 bug (Andrew Poelstra)

Pull request description:

  It looks like cargo versions up to 1.45 have a bug that sometimes causes dependency resolution to fail. There is a straightforward, somewhat ugly fix, which this PR implements.

  In #571 we implemented this and rush-merged it into 0.24.x because (a) it was breaking our CI, (b) it was clearly harmless, even if it turn out not to be the best decision. For this PR I'd like somebody other than me and Sanket to take a look and sanity check us.

  If we merged this, it will also need a backport to 0.25.x.

  For more details see #571 and the linked issues there.
