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.

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`.
This commit tries to achieve separation of signature- and key-related types, previously mixed in a single ECDSA module.
Rationale: bitcoin key types are not specific for signature algorithm.
This is achieved through
- Remove key mod with its content moved to ecdsa mod
- Re-export keys under key module in util mod - to make git generate diff for the rename of ecdsa mod in the next commit correctly.
This is the initial step towards using and maybe enforcing clippy.
It does not fix all lints as some are not applicable. They may be
explicitly ignored later.
Docs can always do with a bit of love.
Clean up the module level (`//!`) rustdocs for all public modules.
I claim uniform is better than any specific method/style. I tried to fit
in with what ever was either most sane of most prevalent, therefore
attaining uniformity without unnecessary code churn (one exception being
the changes to headings described below).
Notes:
* Headings - use heading as a regular sentence for all modules e.g.,
```
//! Bitcoin network messages.
```
as opposed to
```
//! # Bitcoin Network Messages
```
It was not clear which style to use so I picked a 'random' mature
project and copied their style.
* Added 'This module' in _most_ places as the start of the module
description, however I was not religious about this one.
* Fixed line length if necessary since most of our code seems to follow
short (80 char) line lengths for comments anyways.
* Added periods and fixed obvious (and sometimes not so obvious)
grammatically errors.
* Added a trailing `//!` to every block since this was almost universal
already. I don't really like this one but I'm guessing it is Andrew's
preferred style since its on the copyright notices as well.
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
Taking an external dependency just to convert ints to byte arrays
is somewhat of a waste, especially when Rust isn't very aggressive
about doing cross-crate LTO.
Note that the latest LLVM pattern-matches this, and while I haven't
tested it, that should mean this means no loss of optimization.
* add client side block filters with code from murmel. use siphash from bitcoin_hashes pass Bitcoin Core tests upgrade to bitcoin_hashes 0.7
* add filter.filter_id() test use BlockFilter directly
* fixed edge cases of matching empty query sets or or using empty filter
This is a port of the bitcoin-core CPartialMerkleTree and CMerkleBlock classes.
Here they are called PartialMerkleTree and MerkleBlock.
These are useful for SPV clients that wish to verify that a transaction is
present in a specific block in an authenticated way.
This change also moves the secp256k1::Error wrapper from util::Error to
consensus::encode::Error, since we do not use it anywhere else. We can
add it back to util::Error once we have instances of secp256k1::Error
that are not related to consensus::encode.
- Move network::encodable::* to consensus::encode::*
- Rename Consensus{En,De}codable to {En,De}codable (now under
consensus::encode)
- Move network::serialize::Error to consensus::encode::Error
- Remove Raw{En,De}coder, implement {En,De}coder for T: {Write,Read}
instead
- Move network::serialize::Simple{En,De}coder to
consensus::encode::{En,De}coder
- Rename util::Error::Serialize to util::Error::Encode
- Modify comments to refer to new names
- Modify files to refer to new names
- Expose {En,De}cod{able,er}, {de,}serialize, Params
- Do not return Result for serialize{,_hex} as serializing to a Vec
should never fail
- Add serialize::Error::ParseFailed(&'static str) variant for
serialization errors without context
- Add appropriate variants to replace network::Error::Detail for
serialization error with context
- Remove error method from SimpleDecoders
- Separate serialize::Error and network::Error from util::Error
- Remove unneeded propagate_err and consume_err
- Change fuzzing code to ignore Err type
