We are trying to get rid of the `serde_derive` dependency from our
dependency graph.
Stop using default features for the `schemars` dependency which includes
`schemars_derive` which depends on `serder_derive`.
Manually implement `schemars::JsonSchema` instead of deriving it.
We do not need this dependency because we can get the serde derives
directly from `serde`.

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.

7d695f6b41 Improve public re-exports (Tobin C. Harding)
33774122e0 Remove public re-exports from private module (Tobin C. Harding)
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.
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 {
...,
};
```

0c56131819 fix: FeeRate::checked_mul_by_weight should scale output down by 1000 (conduition)
Pull request description:
Fixes a bug in https://github.com/rust-bitcoin/rust-bitcoin/pull/1864. The `FeeRate::checked_mul_by_weight` and by extension the `FeeRate::fee_wu` methods were returning fee amounts scaled up by a factor of 1000, since the internal representation in `FeeRate` is sats per 1000 weight units.
This PR fixes `checked_mul_by_weight` and its unit tests by scaling the output of these methods down by 1000, so that `X sat/vbyte * Y vbytes = X * Y sats`, instead of `X * Y * 1000 sats` as before.
## Before
This code would pass without panic before this PR.
```rust
let weight = Weight::from_vb(3).unwrap();
let rate = FeeRate::from_sat_per_vb(3).unwrap();
assert_eq!(weight * rate, Amount::from_sat(9));
assert_eq!(rate.checked_mul_by_weight(weight), Some(Amount::from_sat(9000)));
```
## After
```rust
let weight = Weight::from_vb(3).unwrap();
let rate = FeeRate::from_sat_per_vb(3).unwrap();
assert_eq!(weight * rate, Amount::from_sat(9));
assert_eq!(rate.checked_mul_by_weight(weight), Some(Amount::from_sat(9)));

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.
This is the final step in removing the explicit `core2` dependency
for I/O in no-std - replacing the `io::Error` type with our own.
Sadly the `std::io::Error` type requires `std::error::Error` as a
bound on the inner error, which is rather difficult to duplicate in
a way that allows for mapping to `std` and back.
To take a more general approach, we use bound on any `Debug`
instead.
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.
With the new `bitcoin_io` library, implementing `io::Write`
manually is somewhat tricky - for `std` users we really want to
provide an `std::io::Write` implementation, however for `no-std`
users we want to implement against our internal trait.
Sadly we cannot provide a blanket implementation of
`std::io::Write` for all types whcih implement our `io::Write`
trait as its an out-of-crate impl.
Instead, we provide a macro which will either implement
`std::io::Write` or our `io::Write` depending on the feature flags
set on `bitcoin_io`.
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 first real step, replacing
`{std,core2}::io::Write` withour own `bitcoin_io::io::Write`. We
provide a blanket impl for our trait for all `std::io::Write`, 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 the coming commits we'll move our `io` module to having its own
implementations of the usual I/O traits and structs. Here we first
move to re-exporting only exactly what we need, allowing us to
whittle the list down from a fixed set.
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.

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.
