The difficulty is a ratio of the max and current targets, since the
max is network specific the difficulty calculation is also network
specific.
We already have network specific maximum target constants, use them when
calculating the difficulty.
Make the `sha512_256` module use similar code layout to the other hash
modules by putting the call to `hash_type` at the top followed by the
`from_engine` function.
Code move only, no other changes.
Currently we are defining the `sha512::Hash` type manually instead of
using the `hash_type` macro.
The generated code using the macro is identical to that without
it (although I didn't actually look at the generated code :)
e21ee381bc Split Prevouts errors out into specific error types (Tobin C. Harding)
Pull request description:
Done as part of the great error clean up.
Currently we are returning a general `Error` from `Prevouts` functions, this is un-informative, we can do better by returning specific types that indicate the exact error path.

fde6479c6a Create uniform build script (yancy)
Pull request description:
Previously, each unique compiler cfg attribute that appeared in the codebase was hard coded and emitted to stdout at compile time. This meant keeping the file up to date as different compiler cfg attributes changed. It's inconsequential to emit a compiler version that's not used, so this change just emits all possibilities to reduce the maintenance burden of the build script.
Note that there is a bit of diff noise in one of the `build.rs` since I simply did a copy of one to the other to make them uniform.

Improve the public exports in two ways:
1. Inline re-exports into the docs of the module that re-exports them.
2. Separate public and private use statements
Recently we discussed a way to separate the public and private import
statements to make the code more clear and prevent `rustfmt` joining
them all together.
Separate public exports using a code block and `#[rustfmt::skip]`. Has
the nice advantage of reducing the number of `#[doc(inline)]` attributes
also.
1. Modules first, as they are part of the project's structure.
2. Private imports
3. Public re-exports (using `rustfmt::skip` to prevent merge)
Use the format
```rust
mod xyz;
mod abc;
use ...;
pub use {
...,
};
```

Add two signing examples to showcase signing a simple one input two

This patch is the result of the recent rust-bitcoin TABConf workshop,
wit bug fix by Sanket, updated to use APIs from tip of master branch.
This code, depending on v0.30.0 is what is being introduced to the
cookbook at the moment.
In an effort to consolidate knowledge spread out over time in various
places on GitHub add a `Policy` section to `CONTRIBUTING.md`.
Add initial sections on import statements, errors, rustdocs,attributes,
and licensing.

875545517d Add clippy exceptions for needless_question_mark lint (Steven Roose)
Pull request description:
This lint forces you to write semantically different code that is in most cases inferior, just to save you 5 characters.
The reason why the code is inferior is because it doesn't do error conversion so it would break when either of the two function signatures changes while in the original code using the `?` operator, nothing would break if the inner error can be converted into the outer error.

d391ada5b8 ci: nightly rustfmt PR scheduled/manual (Einherjar)
Pull request description:
## Summary
- Removes nightly `rustfmt` checks from CI and `CONTRIBUTING.md`. Superseds #2127
- Adds automated nightly `rustfmt` PR creations manual and every Sunday 00:00 UTC. Closes#2128. Closes#1712.
## Details
The new `.github/workflows/rustfmt.yml` action does the following:
1. Checkouts the repo
1. Install the nightly Rust toolchain with `rustfmt` component
1. Run `cargo +nightly fmt` which format all the codebase with the nightly Rust toolchain writing the changes
1. Add the current date in `YYYY-MM-DD` format as an GH action ENV var
1. If changes are detected, create a PR with the following details:
- Title: Automated nightly rustfmt (`DATE`)
- Body: Automated nightly `rustfmt` changes by [create-pull-request](https://github.com/peter-evans/create-pull-request) GitHub action
- Commit message: `DATE` automated rustfmt nightly
- label: `rustfmt`
I did a test run (with `workflow_dispatch` and some minor changes to trigger the PR) in my fork.
Check how the PR looks in https://github.com/realeinherjar/rust-bitcoin/pull/5
Of course, all of these things can be changed.
They are all suggestions...
## Security Disclaimer
We are only introducing a new action, which is quite battle-checked, [`peter-evans/create-pull-request`](https://github.com/peter-evans/create-pull-request) with ~2k stars and proper maintained.

track_caller to accuretly report the test name and line number

The test helper files can panic when calling hex_psbt(). hex_psbt()
will report the calling function, instead of the offending test. Adding
track_caller to functions that call hex_psbt will report the line number
of the failing test.

hex_psbt was added as a macro so that a panic would reveal the line
number of the failing test by expanding the macro at the test location.
However, a stack trace can be used to reveal the test that caused the
failure using RUST_BACKTRACE=1. Furthermore, the track_caller macro is
added to the helper methods which will reveal the line number of the
calling function (the offending test). More detailed information for
debugging has been added to hex_psbt() so that the offending string
will be included in the panic message.
The macro psbt_with_values is used by the psbt test module. Since
there is no pre-processing required, there is no reason to use
metaprogramming here, so this commit moves the logic from a
macro to common function in the test module.

38005f6aa7 Use Target for pow_limit (Tobin C. Harding)
Pull request description:
The `Params::pow_limit` field is currently a `Work` type, this is incorrect. The proof of work limit is the highest _target_ not the lowest work (even though these have a relationship).
Note that we use the highest _attainable_ target, this differs from Bitcoin Core and the reasoning is already documented in the code.
Add new consts and document where they came from as well as how they differ to Core.
Use the new consts in the various network specific `Params` types.

Upgrade the `secp256k1` dependency to the newly released `v0.28.0`.

- Use `secp256k1::Keypair` instead of `secp256k1::KeyPair`.
But to stay in line with the keypair change we deprecate and rename the tweaked alias.
