Jamil Lambert, PhD d099b9c195 Remove wildcard from prelude import
Wildcards have been replaced with what is actually used.

In a couple of cases an additional use statement was added to the test
module to import `DisplayHex` which is only used in test, but
previously imported with the wildcard at the top.

Merge rust-bitcoin/rust-bitcoin#2921: Make 'use core::fmt' calls consistent
8ee1744b9b Make 'use core::fmt' calls consistent (Shing Him Ng)

Pull request description:

  I started taking a look at #2869 and looked for everything that was implementing the `Display` trait:

  ```rust
  impl fmt::Display for _
  ```

  but found some places where the imports weren't consistent:
  ```rust
  impl Display for _
  ```

  There were only a few instances of the latter, so I went ahead and cleaned those up before starting #2869

  I started pulling this thread when I saw the same thing was happening for `fmt::Debug` and `fmt::Formatter` so I updated the rest of the `use core::fmt::*` statements with a few exceptions:

  - No updates to `use core::fmt::*` if it was being called from within a function since I felt like the function scope was small enough to not cause confusion
  - No updates to `use core::fmt::{self, Write as _};`

bitcoin: remove all use of engine/from_engine on opaque hash types
In the next commits we are going to stop exposing the ability to hash
arbitrary data into wrapped hash types like Txid etc. In preparation for
this, stop using these methods internally.

This makes our internal code a little bit uglier and less DRY. An
alternative approach would be to implement the from_engine and engine
methods, but privately (and maybe having a macro to provide this). But I
think this approach is more straightforward.

The one exception is for the Taproot hashes, which are tagged hashes and
currently do not have their own engine type. I will address these in a
later PR because this one is already too big.

Remove usage of blockdata from paths
the `blockdata` directory is code organisation thing, all the
types/modules are re-exported from other places. In preparation for, and
to make easier, the `primitives` crate smashing work - remove all
explicit usage of `blockdata`.

Note that the few instances remain as they seem required e.g.,

  `pub(in crate::blockdata::script)`

Refactor only, no logic changes.

Enforce script size limit when hashing scripts
There are two limits that the Bitcoin network enforces in regard to
hashing scripts

- For P2SH the redeem script must be less than 520 bytes
- For P2WSH the witness script must be less than 10,000 bytes

Currently we are only enforcing the p2sh limit when creating an address
with `Address::p2sh`.

There are various ways to create addresses from script hashes and if
users manually hash a script then use the `ScriptHash` (or
`WScritpHash`) our APIs assume the script that was hashed is valid. This
means there is the potential for users to get burned by creating
addresses that cannot be spent, something we would like to avoid.

- Add fallible constructors to `ScriptHash` and `WScriptHash`
- Add `TryFrom` impls as well to both types
- Remove the `From` impls

Add inherent functions to hashes
Currently we have a trait `Hash` that is required for `Hmac`, `Hkdf`,
and other use cases. However, it is unegonomic for users who just want
to do a simple hash to have to import the trait.

Add inherent functions to all hash types including those created with
the new wrapper type macros.

This patch introduces some duplicate code but we are trying to make
progress in the hashes API re-write. We can come back and de-dublicate
later.

Includes making `to_byte_array`,`from_byte_array`, `as_byte_array`, and
`all_zeros` const where easily possible.

psbt: Return the internal key for key path spend
When signing a Taproot input (in a PSBT) using a key path spend we
currently return the pubkey associated with key that signs. However it
is common to think of the internal key as being the one that signs even
though this is not technically true. We also have the internal key in
the PSBT so matching against it is less surprising.

When using the `Psbt` type to sign a Taproot input using a key path
spend return the internal key.

Merge rust-bitcoin/rust-bitcoin#2458: Support signing taproot in psbt
41e8fb0863 Support signing taproot in psbt (yu)

Pull request description:

  Hi team, I'm from Keystone Wallet team. currently rust-bitcoin does not support signing taproot transactions in psbt.
  We think this founction should be included in the psbt module, we submit this PR. Some context and discussion about this PR can be found here: #2418.

  For this PR, mostly two new functions are introduced:

  - `bip32_sign_schnorr`:  sign a taproot input.
  - `sighash_taproot`: calculate the sighash message to sign a taproot input along with the sighash type.

  Looking forward to your feedback.

a4d01d0b6c Factor out `io::Error` from sighash errors (Martin Habovstiak)

Pull request description:

  The hadnling of `io::Error` in sighash had a few problems:

  * It used `io::ErrorKind` instead of `io::Error` losing inforation
  * Changing `io::ErrorKind` to `io::Error` would disable `PartialEq`&co
  * The `Io` error wariants were duplicated

  It turns out all of these can be solved by moving the `Io` variant into a separate error.

Improve public re-exports
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 {
    ...,
};
```

yancy b166442fb0 Replace hex_psbt macro with test helper function
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.

Make error types uniform
On our way to v1.0.0 we are defining a standard for our error types,
this includes:

- Uses the following derives (unless not possible, usually because of `io::Error`)

  `#[derive(Debug, Clone, PartialEq, Eq)]`

- Has `non_exhaustive` unless we really know we can commit to not adding
  anything.

Furthermore, we are trying to make the codebase easy to read. Error code
is write-once-read-many (well it should be) so if we make all the error
code super uniform the users can flick to an error and quickly see what
it includes. In an effort to achieve this I have made up a style and
over recent times have change much of the error code to that new style,
this PR audits _all_ error types in the code base and enforces the
style, specifically:

- Is layed out: definition, [impl block], Display impl, error::Error impl, From impls
- `error::Error` impl matches on enum even if it returns `None` for all variants
- Display/Error impls import enum variants locally
- match uses *self and `ref e`
- error::Error variants that return `Some` come first, `None` after

Re: non_exhaustive

To make dev and review easier I have added `non_exhaustive` to _every_
error type. We can then remove it error by error as we see fit. This is
because it takes a bit of thinking to do and review where as this patch
should not take much brain power to review.

Use explicit error::Error impl instead of the default
In a further effort to make the code brain-dead easy to read; use an
explicit implementation of `std::error::Error` that returns `None`
instead of relying on the default trait implementation.
