Create a directory `bitcoin` and move into it the following as is with
no code changes:
- src
- Cargo.toml
- contrib
- test_data
- examples
Then do:
- Add a workspace to the repository root directory.
- Add the newly created `bitcoin` crate to the workspace.
- Exclude `fuzz` and `embedded` crates from the workspace.
- Add a contrib/test.sh script that runs contrib/test.sh in each
sub-crate
- Fix the bitcoin/contrib/test.sh script
Error variants should not end with the same identifier as the enum,
i.e., they should not stutter.

For internal macros used only in this crate we do not need to use
`macro_use` and pollute the top level namespace now that we have edition
2018. We can add a `pub(crate) use` statement to each and then path
imports work for the macros like normal types.
When `rust-bitcoin` was started in 2014 the SPDX license list and short
identifiers where not a thing. Now that we have short identifiers and
they are gaining popularity in other projects we can consider using
them.
- Add links to the SPDX website in the readme
- Shorten the author section to a single line
- Remove all the licence information in each file and replace it with an
SPDX ID (see https://spdx.dev/ids/#how)
Of note:
- If the author of a file is explicitly listed, maintain this
information
- If the 'author' is listed as the generic 'Rust Bitcoin developers'
just remove the attribution, this is implicit. This does loose the date
info but that can be seen at any time from the git index using
`git log --follow --format=%ad --date default <FILE> | tail -1`

Pull request description:
As part of the ongoing error improvement work and as a direct result of [this comment](https://github.com/rust-bitcoin/rust-bitcoin/pull/987#issuecomment-1135563287) improve the `Display` implementations of all our error types so as to not repeat the source error when printing.
The first 5 patches are trivial clean ups around the errors. Patch 6 is the real work.
EDIT: ~CC @Kixunil, have I got the right idea here bro?~ Patch 6 now includes a macro as suggested.

ACK 57dd6739c3. Did not check if we covered all cases. We need to remember to use `write_err!` instead of `write!` in future.

Adding an error variant to a public enum is an API breaking change, this
means making what could be small refactorings or improvements harder. If
we use `non_exhaustive` for error types then we mitigate this cost.
There is a tradeoff however, downstream users who explicitly match on
our public error types must include a wildcard pattern.
We implement `source` for all our error types. This means that we should
not display the source error explicitly because users can call `source`
to get the source error.
However, `std::Error::source()` is only available for "std" builds, so
that we do not loose the error source information in "no-std" builds add
a macro that conditionally adds the source onto the error message.

Pull request description:
Now that we have MSRV of 1.41.1 we should use `source` instead of `cause`. Audit the whole codebase and implement `source` for _every_ error type we have.
The first three patches are preparatory cleanup, patch 3 is particularly shameful (adds parenthesis to make my editor work).
CC @Kixunil because he is championing the error stuff.

Use cargo to upgrade from edition 2015 to edition 2018.
cargo fix --edition
No manual changes made. The result of the command above is just to fix
all the use statements (add `crate::`) and fix the fully qualified path
formats i.e., `::Foo` -> `crate::Foo`.
5afb0eaf40 API to get an iterator for funding utxos in psbt (violet360)
Pull request description:
### Current status
The API returns a vector of UTXOs and has return type `Result<Vec<&TxOut>, Error>`
### Expected
The return statement should be of type `sighash::Prevouts` as pointed in #849

Recently we added a bunch of additional sighash types, some of the code
comments became stale. Use the non-specific term 'sighash type' instead
of a particular sighash identifier in comments to make the comments more
applicable.
Our usage of `SigHash` implies that 'sighash' is _two_ words; 'sighash'
is a well known word in the Bitcoin ecosystem it should appear in
identifiers as `Sighash`.
Rename the `NonStandardSigHashType` type and error variant to
`NonStandardSighashType`.
Recently we (*cough* Tobin) made the `Map` trait private and neglected
to add a public API for combining together two PSBTs. Doing so broke the
`psbt` module.
Pull the merge logic out of the `Map` trait and put it in methods on
each individual type (`Input`, `Output`, `PartiallySignedTransaction`).
Doing so allows for simplification of return types since combining
inputs/outputs never errors.
Use the term 'combine' instead of 'merge' since that is the term used in
BIP 174.
Rust idiomatic style is to put the rustdoc _above_ any attributes on
types, functions, etc.
Audit the codebase and move comments/attributes to the correct place.
Add a trailing full stop at times to neaten things up a little extra.
Based on the original work by Justin Moon.
*MSRV unchanged from 1.29.0.*
When `std` is off, `no-std` must be on, and we use the [`alloc`](https://doc.rust-lang.org/alloc/) and core2 crates. The `alloc` crate requires the user define a global allocator.
* Import from `core` and `alloc` instead of `std`
* `alloc` only used if `no-std` is on
* Create `std` feature
* Create `no-std` feature which adds a core2 dependency to polyfill `std::io` features. This is an experimental feature and should be
used with caution.
* CI runs tests `no-std`
* MSRV for `no-std` is 1.51 or so
