Currently we derive `impl Debug for PrivateKey` for "std" builds and
manually implement an obfuscated version for "no-std" builds. Since
we enable the `hashes` feature of `rust-secp` this is unnecessary
because secp takes care of obfuscating the secret for us.

Pull request description:
In order to support standard (de)serialization of structs, the
`rust-bitcoin` ecosystem uses the standard `std::io::{Read,Write}`
traits. This works great for environments with `std`, however sadly
the `std::io` module has not yet been added to the `core` crate.
Thus, in `no-std`, the `rust-bitcoin` ecosystem has historically
used the `core2` crate to provide copies of the `std::io` module
without any major dependencies. Sadly, its one dependency,
`memchr`, recently broke our MSRV.
Worse, because we didn't want to take on any excess dependencies
for `std` builds, `rust-bitcoin` has had to have
mutually-exclusive `std` and `no-std` builds. This breaks general
assumptions about how features work in Rust, causing substantial
pain for applications far downstream of `rust-bitcoin` crates.
This is mostly done, I'm still finalizing the `io::Error` commit at the end to drop the `core2` required dep in no-std, but its getting there. Would love further feedback on the approach or code-level review on these first handful of commits.

Pull request description:
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.

3. Public re-exports (using `rustfmt::skip` to prevent merge)

In order to move towards our own I/O traits in the `rust-bitcoin`
ecosystem, we have to slowly replace our use of the `std` and
`core2` traits.
Here we take the second big step, replacing
`{std,core2}::io::Read` with our own `bitcoin_io::io::Read`. We
provide a blanket impl for our trait for all `std::io::Read`, if
the `std` feature is enabled, allowing users who use their own
streams or `std` streams to call `rust-bitcoin` methods directly.
Since we are no longer relying on the blanket `io::Write` impl for
`&mut io::Write`, we should now ensure that we do not require
`Sized` for our `io::Write` bounds, as its unnecessarily
restrictive and can no longer be worked around by simply adding an
`&mut`.
`std::io::Write` is implemented for all `&mut std::io::Write`. This
makes it easy to have APIs that mix and match owned `Write`s with
mutable references to `Write`s.
However, in the next commit we add our own `Write` trait which we
intend to implement for all `std::io::Write`. Sadly, this is
mutually exclusive with a blanket implementation on our own
`&mut Write`, as that would conflict with an `std::io::Write`
blanket impl.
Thus, in order to use the `Write for all &mut Write` blanket impl
in rust-bitcoin, we'd have to bound all `Write`s by
`std::io::Write`, as we're unable to provide a blanket
`Write for &mut Write` impl.
Here we stop relying on that blanket impl in order to introduce the
new trait in the next commit.
In order to support standard (de)serialization of structs, the
`rust-bitcoin` ecosystem uses the standard `std::io::{Read,Write}`
traits. This works great for environments with `std`, however sadly
the `std::io` module has not yet been added to the `core` crate.
Thus, in `no-std`, the `rust-bitcoin` ecosystem has historically

for `std` builds, `rust-bitcoin` has had to have
mutually-exclusive `std` and `no-std` builds. This breaks general
assumptions about how features work in Rust, causing substantial
pain for applications far downstream of `rust-bitcoin` crates.
Here, we add a new `bitcoin_io` crate, making it an unconditional
dependency and using its `io` module in the in-repository crates
in place of `std::io` and `core2::io`. As it is not substantial
additional code, the `hashes` io implementations are no longer
feature-gated.
This doesn't actually accomplish anything on its own, only adding
the new crate which still depends on `core2`.

Currently we have functions on `Address` that call through to a public
`Payload` type. The `Payload` type is an implementation detail and
should never have been public. In preparation for modifying the
`AddressInner` and removing `Payload` altogether lets move all the
functionality from `Payload` into `Address` - this is basically just
code moves so it is feasible to review with some confidence.
This is an API breaking change because it makes `Payload` private and
also removes from the pubic `Address` API functions that accept and
return `Payload`. Apart from that the changes can be seen as
refactoring.
The `AddressEncoding` type exists solely to assist us in implementing
`Display` on `Address`, it may have been used in the past by alt-coins
back when we had a more tolerant outlook on supporting them. Nowadays
we explicitly do not support alts.
Not sure what happened here but our release job didn't catch this? We
should have updated this to "since = 0.31.0" before release. Since we
only deprecate for one release lets go ahead and remove this.
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.

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.

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.
