A release or so ago we added `non_exhaustive` to the `Network` enum,
this turned out to make usage of the enum un-ergonomic for downstream
users. After much debate we decided that a way forward was to just
minimize the usage of the enum in the public API by instead use
`AsRef<Params>` so that downstream could define their own network enum
based on the networks they support.
Minimize usage of `Network` by using `AsRef<Params>` as a parameter type
instead. "minimize" because the `Network` still appears in some places.
Currently `Magic` has per network consts but no way to dynamically get
the magic bytes for a network. Note also that we are currently trying to
reduce the usage of `Network` in the public API.
Add a public constructor to the `Magic` type that accepts a `Params`
parameter to determine the network to use.

Pull request description:
When computing the maximum difficulty transition threshold we forgot to check that the returned `Target` is not bigger than the maximum. This value is network specific so keep the original logic but with `_unchecked` on the function name.
This was noted in the discussion on #2161

The maximum target threshold has a network dependant upper bound.
Currently we are not checking this bound. One complication is that there
is currently heated open debate around the `Network` type.
We can bypass the `Network` issue by using `AsRef<Params>` instead.
Add a function that does the checks based on the `Params` type as well
as an unchecked version.
These two functions calculate the min/max threshold transition which is
a _target_ not a "difficulty" number. Using "difficulty" in the function
name is unnecessarily confusing.
Rename and deprecate the functions.
The maximum "attainable" target is a `rust-bitcoin` thing, Core use max
unattainable.
Deprecated the `Params::pow_limit` field and add a new field
`max_attainable_target`.
The `Params` type is `non_exhaustive` so this is not an API breaking
change.
What we really want is the maximum target, but since this is a const in
`Params` use an `AsRef<Params>` argument in the `difficulty` functions.
Requires implementation of `AsRef<Params> for Params`.
The `difficulty` calculation requires dividing a target value by `self`.
Add an assertion that `self` is not zero to help devs debug this.
Note that this should never really be hit, but its possible there is a
bug somewhere causing the target to be set to zero - so this may help
debugging.
Also, add panics section to rustdocs.
This lint triggers when parsing a reference to a large struct as a
generic argument, which is wrong.
Allow it crate wide because [subjectively] this lint never warns for
anything useful.

Pull request description:
TL;DR As we do for `absolute::LockTime` and for the same reasons; implement `ArbitraryOrd` for `relative::LockTime`.
locktimes do not have a semantic ordering if they differ (blocks, time) so we do not derive `Ord` however it is useful for downstream to be able to order structs that contain lock times. This is exactly what the `ArbitraryOrd` trait is for.

`require_network` is typically called as part of parsing, often in the
same line of code. Counter to our normal errors, it makes
`require_network` more ergonomic to use if we just return a `ParseError`
variant.
Close: #2507
Done in preparation for adding the `NetworkValidationError` as a variant
of `ParseError`.
Move the `NetworkValidationError` type to beneath `ParseError`.
Code move only, no other changes.

When we renamed `dust_value` to `minimal_non_dust` we forgot to keep the

Pub back in deprecated `dust_value`, linking to the rename.
Adds constructors to allow directly creating locktimes from time or
block counts; adds a flooring constructor to Time to match the ceiling
one; adds an explicit constructor to Height since the From<u16> was not
very discoverable.
These two functions are related. We cannot, by definition, get the
witness version from a script that is not a witness program but
currently the code is not linking these two things.
Refactor by doing:
- Move the check of the witness program bip rules to `witness_version`
- Call `witness_version().is_some()` in the predicate
Improve the docs while we are at it to include the bip text in the
rustdoc. Note I didn't bother referencing the segwit bip number, this
bip text is pretty well known.
Add two unit tests that verify we can correctly determine if a
shortest allowed and longest allowed script is a witness program.
Done in preparation for patching the `witness_version` function.
In preparation for release add a changlelog entry and bump the version.
I'm not 100% sure that this release is API breaking, dependencies
definitely changed. The rest might be only additives but I didn't bother
looking exactly because I think its better to bump the minor version and
err on the side of caution.
Note the hashes 0.13.0 dependency stays in the dependency graph because
of secp, we can update secp after releasing `hashes` then update the
secp dependency in `rust-bitcoin` thereby removing the `hashes v0.13.0`
dependency - phew.
We are currently using the `base58::Error` type to create errors in
`bitcoin`, these are bitcoin errors not `base58` errors.
Note that we add what looks like duplicate
`InvalidBase58PayloadLengthError` types but they are different because
of the expected length. This could have been a field but I elected not
to do so for two reasons:
1. We will need to do so anyways if we crate smash more
2. The `crypto::key` one can have one of two values 33 or 34.
With this applied we can remove the now unused error variants from
`base58::Error`.

b816c0bb01 hash_types: add unit tests for display of all hash types in the library (Andrew Poelstra)
Pull request description:
This can be checked against the 0.29.x branch, and against the commit prior to #1659 (40c246743b^) and you will see that it is consistent EXCEPT:
* In rust-bitcoin 0.29.x we did not have multiple sighash types, only `Sighash`; we now have `LegacySighash`, `SegwitV0Sighash`, and `TapSighash`.
* In #1565 we deliberately changed the display direction of the sighashes, to match BIP 143.
