Pull request description:

  `hashes 1.0.0` can't be far away, here is a quick polish (done while I waited for my car to get fixed).

  Everything here is internal except stuff to docs. Note please I claim "internal change only" in a bunch of patches that do code moves but these effect the docs build because order is preserved in some instances.

hashes: Move engine functions
The `sha256t` module is unique in that it implements its methods
manually (as call throughs) instead of using the macros. To make it more
clear what is implemented re-order the engine constructor and getter to
better mirror the layout in the macros.

Internal change only.

hashes: Re-order from_byte_array
The `hashes` crate has a bunch of similar types defined by a bunch of
similar macros and impl blocks, all of which makes it difficult to tell
exactly what is implemented where. In an effort to make the code easier
to read order the `from_byte_array` constructor in the same place across
the crate. Note also we typically put constructors up the top, also
`from_byte_array` is the likely most used constructor so put it first.

FWIW I discovered this while polishing the HTML docs.

Internal change only.

hashes: Rename hash_type macro
Conceptually (and using traits) we split the hashes into "general"
hash types and more restricted hash types (`Hash`). Also we observe that
the `hash_type` macro defines all the inherent functions name
identically to the `GeneralHash` trait methods.

Rename the trait to describe better what it does.

Internal change only.

hashes: Move from_engine function to other macro
The `from_engine` function is associated with a general hash type but we
are defining it in the `hash_type` macro which holds nothing but
functions associated with the `Hash` trait. By "associated" I mean
methods on the type as opposed to trait methods.

In preparation for re-naming the `hash_type` macro move the
`from_engine` function there. Requires duplicating the code in the
`siphash` impl block, this is as expected because the `siphash` requires
a custom implementation of the general hashing functionality.

Internal change only.

Warn on future deprecations
We use `TBD` in our `deprecated` string and it was discovered that there
is an exception on this string so as not to warn because it is used
internally by the Rust language. However there is a special lint to
enable warnings, lets use it.

Add `#![warn(deprecated_in_future)]` to the coding conventions section
of all crates except `fuzz`.

Merge rust-bitcoin/rust-bitcoin#3296: Remove the `SliceIndex` implementation from hash types
3b7ba4f977 Remove the SliceIndex implementation from hash types (Tobin C. Harding)

Pull request description:

  If folk really want to index into a hash they can us `as_byte_array` then index that.

  Includes a bump to the version number of `hashes` to `v0.15.0` - this is because otherwise `secp` won't build since we are breaking an API that is used in the current release of secp.

Pull request description:

  In b9643bf3e9 we introduced an incorrect `cfg` attribute, that has just shown up, no clue why clippy only just presented me with this error now. Anywho, the current code is buggy and the rustdoc tests are never being run.

  Fix `cfg` attribute to use the feature name correctly and fix the imports so the code runs.

  Maintain the explicit `main` so that we can return an error using the `?` operator. Remove the empty `main` because its not needed anymore, it is a hang-over from Rust back in the day (before main was automatically added, IIUC).

Martin Habovstiak fb5971cc2b Fix UB in `siphash24`
The code in `siphash24` was obtaining the pointer in buffer at offset by
accessing an element at that offset instead of accessing a range or
simply computing the offset of the pointer from the start. This is UB
because one canot access past `T` even if the allocation is known to be
large enough. This change fixes it by using a range and also replaces
complicated code with simpler use of `from_le_bytes`.

It's quite likely that this can be improved further, possibly even
removing the `unsafe` without speed penalty but it's a larger task
that's not a priority right now.

d72f730211 hashes: Use $crate in internal macros (Tobin C. Harding)

Pull request description:

  These are only called from within the crate but it is still more correct to use `$crate` and saves this from biting us later if we copy the code someplace else.

Deprecate `from_slice()` in sha256.rs
Support for Rust arrays is now much better so slice-accepting
methods that require a fixed length can be replaced with a method that
accepts an array.

`from_slice()` has been deprecated. A `from_byte_array()` function
already exists to be used instead.

Allow unused imports when running bench code
Running the bench code results in a million warnings, instead of
solving these just allow unused imports as we do for fuzz code.

94c0614bda Enforce that `Hash::Bytes` is an array (Martin Habovstiak)

Pull request description:

  This makes sure `Hash::Bytes` is an array. We've discussed this somewhere but I don't remember where.

  I'm not sure if the second commit is actually valuable but hopefully shouldn't make things worse.

Martin Habovstiak be13397570 Make hmac & hkdf more robust against buggy `Hash`
Use the newly added requirement that `Hash::Bytes` is an array to
protect the implementation of hmac and hkdf against implementations that
would accidentally return slices of different sizes from the `AsRef`
impl.
