I hope putting it on the most notorious type where people actually notice it is enough. I couldn't find a good way to put it on all other `sha256d` automatically, and copy pasting it seems not worth it.

Pull request description:
Add non_exhaustive compiler directive to AddressType
Currently adding variants to enums is a breaking change. In an effort to
reduce the upgrade burden on users we can use the `non_exhaustive`
compiler directive so that adding a new variant does not cause
downstream code to break.
Add `non_exhaustive` to the `AddressType` since it may be extended in
the future.

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.

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.

71bf19621a Use fully qualified path in macro (Tobin Harding)
Pull request description:
The Lightning network defines a type called 'chain hash' that is used to uniquely represent the various Bitcoin networks as a 32 byte hash value. Chain hash is now being used by the DLC folks, as such it is useful to have it implemented in rust-bitcoin.
One method of calculating a chain hash is by hashing the genesis block for the respective network.
Add a `ChainHash` type that can be used to get the unique identifier of each of the 4 Bitcoin networks we support. Add a method that calculates the chain hash for a network using the double sha256 of the genesis block. Do so using hard coded consts and add unit tests (regression/sanity) that show these hard coded byte arrays match the hash of the data we return for the genesis block for the respective network.
The chain hash for the main Bitcoin network can be verified from LN docs (BOLT 0), add a link to this document.

Rust has naming conventions surrounding conversion functions
We have a handful of methods that are not following convention. This PR is done as three patches, separated by incorrect function name (`into_` or `as_`) and by whether or not the original method needs deprecating. Can be squashed if folks prefer.
From the docs: https://rust-lang.github.io/api-guidelines/naming.html

| | | owned -> owned (Copy types)
into_ | Variable | owned -> owned (non-Copy types)
EDIT: I did actually audit all uses of `to_` when I first did this, I did this by grepping for `fn to_` and checking the output against the table.

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.
As things are right now, memory exhaustion protection in `Decodable`
is based on checking input-decoded lengths against arbitrary limits,
and ad-hoc wrapping collection deserialization in `Take`.
The problem with that are two-fold:
* Potential consensus bugs due to incorrect limits.
* Performance degradation when decoding nested structured,
due to recursive `Take<Take<..>>` readers.
This change introduces a systematic approach to the problem.
A concept of a "size-limited-reader" is introduced to rely on
the input data to finish at enforced limit and fail deserialization.
Memory exhaustion protection is now achived by capping allocations
to reasonable values, yet allowing the underlying collections
to grow to accomodate rare yet legitmately oversized data (with tiny
performance cost), and reliance on input data size limit.
A set of simple rules allow avoiding recursive `Take` wrappers.
Fix#997
A better way to write a byte string is to use write all so that
`ErrorKind::Interupted` is not returned.
Use `write_all` to write the non-sense (error indication) string to the
writer when we hit the SIGHASH_SINGLE bug.
Rust convention is to use `to_` for conversion methods that convert from
an owned type to an owned `Copy` type. `as_` is for borrowed to borrowed
types.
Re-name and deprecate conversion methods that use `as_` for owned to
owned `Copy` types to use `to_`.
Rust convention is to use `to_` for conversion methods that convert from
an owned type to an owned `Copy` type. `into_` is for owned to owned
non-`Copy` types.
Re-name and deprecate conversion methods that use `into_` for `Copy`
types to use `to_`.
`self` and the referenced type returned by `as_inner` are both `Copy`
types. There is no need to provide an reference getter method to a
`Copy` type since implementing `Copy` implies that copying is cheap.
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.
