There is a range of different wordings used in the docs of constructor
type functions.
Change all to start with `Constructs a new` or `Constructs an empty`.
In functions that act like constructors there is a mixture of the usage
of `creates` and `constructs`.
Replace all occurrences of `creates` with `constructs` in the first line
of docs of constructor like functions.

The length of the slices is not a safety invariant.
Fairly large diff because I had to remove a bunch of `unsafe` blocks
around calls to this function.
Fixes#3531
We have a couple of problems:
1. There are two macros currently for fmt stuff that do similar things,
`arr_newtype_fmt_impl` and `hex_fmt_impl` - the difference is not
immediately obvious, its the way that the byte array is iterated.
2. Our hash types are missing `AsRef<[u8; len]>` and `Borrow<[u8; len]>`.
Introduce a new macro and remove a bunch of other macros. Include
extensive docs but hide the macro from public docs because its not
really for consumers of the library.
The macro requires `$crate::hex` to point to `hex-conservative`.
Note the macro is pretty generic (as in general purpose), `hashes` might
not be the right home for it. Potentially a better place would be in
`hex` itself?
This has been fixed and we use nightly to lint so we have access to the
merged fix.
Removing the attribute uncovers a bunch of real lint warnings, fix
them while we are at it.

Pull request description:
Use `to_vec` and deprecate `to_bytes`, the opposite of what we did in #2585.
For functions that return a `Vec` by first allocating use function name `to_vec`. This explicitly excludes:
- Functions that return an array (`CompressedPublicKey::to_bytes`)
- Functions that consume self and return a `Vec` without allocating (`ScriptBuf::into_bytes`)
See #3025 for discussion and consensus.

As we have been doing in other places deprecate `to_bytes` in favour of
`to_vec`. Note this is only for functions that return a `Vec`, the `key`
module has `CompressedKey::to_bytes` still as it returns an array.
During this release cycle we deprecated `to_vec` in favour of
`to_bytes`, we have since reversed our position on the name.
Remove the deprecation of `to_bytes` from the three types that had it
and use `to_vec`.
In the `script` module remove the wildcards and re-export stuff from
`self` explicitly in both `primitives` and `bitcoin`.
Internal change only, everything is re-exported.
The current feature gating is wrong, this bug is unreleased because it
was introduced #2585.
The `impl_array_newtype` macro is only used in the `bitcoin` crate, it
does not need to be in `internals`. Also, other crates have an `alloc`
feature which `bitcoin` does not have so if we ever need it in other
places we'll need a duplicate with the correct feature gating anyways.
Move the macro to `bitcoin::internal_macros` and remove the incorrect
`alloc` feature gating.
WARNING: This is not like all the other extension traits.
Because of the use of generics on various `Transaction` methods it is
not easily possible to use the `define_extension_trait` macro.
Manually create the extension traits (public and private) for the
`Transaction` type. This is quite ugly but c'est la vie
(Includes two in the `transaction` module and one in the
`consensus_validation` module.)
Currently `script_pubkey_lens` returns a generic `Iterator` using `impl`
syntax. This syntax is not supported in traits and we want to move the
function to the soon-to-be-added `TransactionExt` trait.
Add a struct to hold the iterator returned by `Map`, this is ugly but
its the least ugly thing I could come up with.
Split the `Transaction` impl block into three parts:
- The bits going to `primitives`
- The bits staying in a public extension trait
- The bits staying in a private extension trait
Internal change only.
It is acceptable to use a wildcard import in bench code for the same
reasons it is acceptable in the `tests` module.
In preparation for introducing extension traits in the `transaction`
module use wildcard import in the module's bench code.
66da2266e2 Explicitly re-export stuff from crates down the stack (Tobin C. Harding)
Pull request description:
Up until recently we were using wildcard re-exports for types moved to `units` and `primitives`. We have decided against doing so in favour of explicit re-exports.
Audit `units` and `primitives` using `git grep 'pub enum'` (and `struct`) and explicitly re-export all types.
Remove all wildcards except for the re-exports from `opcodes`, there are too many opcodes, explicitly re-exporting them does not aid clarity.

Pull request description:
The `consensus::deserialize` and `consensus::deserilaize_partial` functions should not return an I/O error. Doing so causes various other error types to include an `io::Error` and the `io::Error` is an annoying type to work with.
This PR is a bunch of steps, and it took me a good while with quite a bit of backtracking to get here. As such you may want to review the final state before looking at each patch.
The `consensus` errors can be further cleaned up but I'd prefer not to spend more time on this unless it has some chance of merging.

The `consensus::encode::Error` contains an IO error but reading from a
buffer only ever errors for EOF. We converted all instances of EOF to
`MissingData` already so now we can split the IO error apart from the
actual encoding errors variants.
The `encode::Error::ParseFailed` variant holds an inner string, this is
suboptimal.
In an effort to patch the `encode::Error` while mimizing the diffs
required add a helper function that creates the variant. The benefit is
that later patches that effect this variant will only need to update the
constructor function and not every call site.
Internal change only.
The extension traits are temporary just while we try to stabalize
`primitives`, they are not intended to be implemented by downstream.
Seal the extension traits so that downstream crates cannot implement
them.

Move the `Witness` over to `primitives` leaving behind any method that
takes or returns a `Script` or a signature.
Includes addition of a feature gate to unit test.
In preparation for moving the `Witness` to `primitives` we need a way to
construct the `Witness` when decoding. In order to maintain the current
performance and not introduce additional allocations we need to be able
to construct a `Witness` from the content buffer, this leaks the
implementation details of `Witness`.
Add a clearly marked unstable constructor to create a `Witness` from
parts. This introduces the concept of `foo__unstable` function names;
add a section to the README describing unstable functions and semver
guarantees.

We want to move the `block_hash` function to `primitives` but it uses
`Encodable` which currently lives in `bitcoin`. Just implement it
manually.
We added a regression test already in a previous commit to check that
this is correct.
We had an initial go at this but we didn't do the `Hash` trait method.
In order to do so we need to hack the serde code a fair bit, note the
public visitor types.
Recently we deprecated `to_vec` in favour of `to_bytes` however we
continued to use `to_vec` in a few places. This wasn't noticed because
of our usage of `TBD` in the `deprecated` attribute.
Use `to_bytes` instead of `to_vec`.
