Clippy warns about creating a reference that is immediately
de-referenced.
Remove unnecessary explicit `&`, while we are at it remove unnecessary
explicit types that appear on the same lines of code.

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.

2e7effc604 Feature `use-serde` renamed to `serde` (Martin Habovstiak)
Pull request description:
Features activating external crates are supposed to have same name as
those crates. However we depend on same feature in other crates so we
need a separate feature. After MSRV bump it is possible to rename the
crates and features so we can now fix this inconsistency.
Sadly, derive can't see that the crate was renamed so all derives must
be told to use the other one.
Replaces #373

99f565f932 Add non_exhaustive to all error enums (Tobin C. Harding)
Pull request description:
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.

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.
Features activating external crates are supposed to have same name as
those crates. However we depend on same feature in other crates so we
need a separate feature. After MSRV bump it is possible to rename the

Clippy emits:
warning: you should consider adding a `Default` implementation for
`TaprootBuilder`
As suggested, implement `Default` or `TaprootBuilder`.
Clippy emits:
warning: you are using an explicit closure for copying elements
In one instance we have `map` followed by `flatten`, this can be
replaced by the `flat_map` combinator.
As suggested use `copied` combinator.
Clippy emits:
warning: unnecessary `if let` since only the `Some` variant of the
iterator element is used
Use combinator chain `iter().flatten().any()` to check for an node with
hidden nodes.
Clippy emits:
warning: this expression creates a reference which is immediately
dereferenced by the compiler
As suggested, remove the additional reference.

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.

Parenthesis are not needed around this expression but my editor is going
mad and cannot format the code without them. Since it does not hurt
readability add parenthesis around the expression.
Since commit `commit 275adc6c335a4326699cfbd444949e1725864ea1` on
`bitcoin_hashes` we have the identical implementation of the macro
`sha256t1_hash_newtype` in this crate and in `bitcoin_hashes`.
Remove the `sha256t_hash_newtype` macro from this crate in favour of the
one in `bitcoin_hashes`.
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`.

As has been done in other places in the codebase; improve the docs in
the `taproot` module by doing:
- Use full sentences (capital letters + full stops)
- Use back ticks and links for types where appropriate
- Fix grammar
- Fix stale docs
- Use third person for describing functions
- Use 100 character line width
- Use markdown sections (`# Examples`, `# Returns`) where appropriate
- Separate brief heading from extended description when appropriate
- Use `///` for all functions/types (both private and public)
I also did:
- Build the docs and check all the links
- Read all the built docs, check for sanity and pretty-ness
208eb65f1b Make NodeInfo API public (sanket1729)
Pull request description:
Reported by @shesek. Users might find it convenient to manually construct the tree using `NodeInfo` API
```rust
let leaf1 = NodeInfo::from_leaf_with_ver();
let leaf2 = NodeInfo::from_leaf_with_ver();
let root = NodeInfo::combine(leaf1, leaf2);
let spend_info = TaprootSpendInfo::from_node_info(&secp, internal_key, root);

The exact code formatting we use is not as important as uniformity.
Since we do not use tooling to control the formatting we have to be
vigilant ourselves. Recently I (Tobin) changed the way default type
parameters were formatted (arbitrarily but uniformly). Turns out I
picked the wrong way, there is already a convention as shown in the rust
documentation online (e.g. [1]).
Use 'conventional' spacing for default type parameters. Make the change
across the whole repository, found using
git grep '\<.* = .*\>'
[1] - https://doc.rust-lang.org/book/ch19-03-advanced-traits.html
In this library we specifically do not use rustfmt and tend to favour
terse statements that do not use extra lines unnecessarily. In order to
help new devs understand the style modify code that seems to use an
unnecessary number of lines.
None of these changes should reduce the readability of the code.
