Currently various features fail to build when enabled without default
features. This is because many tests need feature gating.
Feature gating the import statements quickly turns into spaghetti when
trying to cover all combinations of two features correctly, instead just
allow unused imports on `tests` modules where needed.
Add correct feature requirements to the examples so they also can be run
without default features.
Improve the CI script by doing:
- Add `std` to the feature matrix.
- Add `--no-default-features` to test runs in the CI script.
The examples depend on having the "std" feature [1]. In preparation for
being able to run tests with `--no-default-features` add the "std"
feature as a requirement for all three examples. While we are at it use
the correct rand feature requirement: `rand-std`.
[1] Technically we only need "alloc" but "alloc" is not working with
Rust 1.29 currently so just use "std".
The `Debug` implementation for secrets is feature gated on `std` because
it uses a hasher from `std`. If `bitcoin_hashes` is enabled we can use
it for hashing. If neither `std` nor `bitcoin_hashes` is enabled fall
back to outputting:
<secret requires std or bitcoin_hashes feature to display>
Remove the docs conditional since we now implement `Debug` always.
When building with --no-default-features the compiler emits:
warning: unused import: `mem`
The call site is feature gated so we either need to feature gate the
import or use a fully qualified path. Since 'core' is quite short elect
to use the fully qualified path.

Pull request description:
This PR is an initial attempt to more thoroughly test our public API.
Add examples to various types/methods/functions in the key module.
I'm not entirely sure when is enough, do we want an example on every single public method, function, and type or is this overkill. In this PR I tried to find a balance by doing ever method/function that took an argument that is a custom type from this lib. I think this should be extended to include return values too though ...
Thanks to @thomaseizinger for the idea!
First 2 patches are docs improvements to `lib.rs`.

6fad20ef0c Fix the mess around Parity (Tobin Harding)
Pull request description:
Recently we made a wee mess with the `Parity` opaque type. Let's fix it
up by doing:
- Use an enum with variants `Even` and `Odd`.
- Add explicit conversion methods to/from u8 and i32
- Implement `BitXor`
This PR attempts to follow the plan laid out in the issue but:
- I don't get why`to_u8` is requested, I added it anyways.
- `to_i32` is not mentioned but we need it if we are going to pass the parity back to FFI code after receiving it _without_ having to care about the value. And that is the whole point of this `Parity` type in the first place.
- I don't get why `from_xxx` is fallible, when is an integer not even or odd?
Please note: This patch is an API breaking change that does _not_ follow the deprecation guidelines. Rust does not allow deprecating `From` impl blocks AFAICT.

We recently patched much of the docs in the `key` module, lets attempt
to attain perfection.
Improve docs by doing:
- Use full stops
- Use 100 character column width
- Use plural third person tense
- Use plural for section headings
- Fix any grammar mistakes
- Use code ticks and links as appropriate
Done in an effort to better test our public API.
Add tests in the `Examples` section as is idiomatic in the Rust
ecosystem.
Make other minor improvements to any rusdocs we touch:
- Use full stops
- Use 100 character column width
- Use plural third person tense
- Use plural for section headings
Improve method docs by doing:
- Remove 'batch' comment
- Remove mention of required features, docs already show this
- Use links to types as well as ticks

Pull request description:
Recently we deprecated a bunch of functions/methods that used the term `schnorrsig`. Seems we left `generate_schnorrsig_keypair` in there, along with some stale docs on it.
- Patch 1: Adds method `KeyPair::public_key` that calls through to `XOnlyPublicKey::from_keypair`.
- Patch 2: Deprecates `generate_schnorrsig_keypair` and uses the newly defined `pk.public_key()` everywhere.

Recently we deprecated a bunch of methods/functions. We are still
calling them in test code. Found by Clippy.
Use the shiny new methods/functions instead of the deprecated ones.
We have deprecated all other functions that use the identifier
'schnorrsig' but we missed `generate_schnorrsig_keypair`.
This function is purely a helper function and serves no real purpose
other than to reduce two lines of code to a single line. Downstream
users can write this function themselves if they need it.
Also, we recently added a new public method to `KeyPair` to get the
public key in a slightly more ergonomic fashion. Use `kp.public_key()`
when replacing usage of now deprecated `generate_schnorrsig_keypair`
function.
Currently to get the `XOnlyPublicKey` from a `KeyPair` users must do
`XOnlyPublicKey::from_keypair(&kp)`. While this does the job we can make
the lib more ergonomic by providing a method directly on `KeyPair` that
calls through to `XOnlyPublicKey::from_keypair`.
Add method `KeyPair::public_key(&self)`.

Pull request description:
We can use the linters to help us catch type definitions that are missing 'standard' derives. 'standard' is project defined to be
- Copy
- Clone
- Debug
- PartialEq and Eq
- PartialOrd and Ord
- Hash
(I've assumed this to be true based on the code and an open [PR](https://github.com/rust-bitcoin/rust-bitcoin/pull/587) in rust-bitcoin.)
While neither Rustc nor Clippy can find all of these, Rustc can warn for missing `Copy` and `Debug` implementations and these warnings can assist us find types that may need additional derives.
First two patches are trivial Clippy fixes in preparation for using the linter to improve type definitions crate wide.
Patch 3 adds
```
#![warn(missing_copy_implementations)]
#![warn(missing_debug_implementations)]
```
and fixes newly emitted warnings.

Previously only `global-context-less-secure` was shown in the doc even
though `global-context` may also work. This was strictly correct because
`global-context` implies `global-context-less-secure` which is also
documented but people could miss it or forget about it and then worry
about security or worse, enable less secure feature.
Calling out both fetures seems useful, even important and thankfully
doesn't seem to cause too much noise in the docs.
Currently we have an implementation of `Debug` (also used by `Display`)
for `Signature` that first converts the sig to a `SerializedSignature`
then prints it as hex.
We would like to have an implementation of `Debug` for
`SerializedSignature`, this cannot be derived because of the `data: [u8;
field]`. We can manually implement `Debug` for `SerializedSignature`
exactly as it is currently done for `Signature` and call this new
implementation from `Signature::fmt()`.
This code path is already tested in `lib.rs` in the test function
`signature_display`.
Rustc can warn us when we forget to add `Copy` and `Deubg` trait
implementations to types.
Add lint directives to enable warnings for missing `Copy` and `Debug`
implementations. Use the newly emitted warnings to find types that do
not implement our 'standard' traits. These 'standard' traits are defined
as the set of attributes that it has been found beneficial to
opportunistically add to all types, these are
- Copy
- Clone
- Debug
- PartialEq and Eq
- PartialOrd and Ord
- Hash
