Pull request description:
As proposed in https://github.com/rust-bitcoin/rust-bitcoin/issues/510#issuecomment-881686342 this PR raises the MSRV to 1.41.1 it also changes the code to be Edition 2018.
The PR contains a few things:
* Moving to edition 2018 and fixing the imports
* Sorting and combining imports to make them more concise
* Replacing our c_void with `core::ffi::c_void`
* Bumping the `rand` version to latest and modifying our `RngCore` implementations accordingly
* Doing some small refactoring and using the new `TryInto` trait where it makes the code nicer
If people prefer I can split this PR into multiple and/or drop some commits

Recently we fixed a bunch of feature gates to use `rand-std` instead
of `rand` but in doing so did not notice that the same feature gates
were using `alloc` which is meaningless if `std` is enabled.
Feature gate on `std` if we are using `rand-std`.

Pull request description:
In a continued effort to find my feet around here, and inspired by issue #128 I've done a codebase wide audit of the docs (primarily just rustdocs but I glanced at `//` docs as well). Each change is in a separate commit so can be removed if resistance is met. (_"resistance is futile"_).
I've based the stylistic decisions on [work done](https://github.com/rust-bitcoin/rust-bitcoin/pull/704) in rust-bitcoin.
I believe the only controversial change is the last (commit: da161c9 Use rust-bitcoin module doc style), please review that one carefully.

4c43d5e20f Add custom Debug impl for RecoverableSignature (Tobin Harding)
Pull request description:
Currently when debug printing the `RecoverableSignature` we do so byte by byte, this means that the output differs depending on the endianess of the machine. If instead we serialize the signature in compact form then the output is the same irrespective of the endianess.
With this applied the following two commands now pass:
```
cargo test test_debug_output --features=recovery
```
```
cross test --target powerpc-unknown-linux-gnu test_debug_output --features=recovery
```
Fixes: #375

Our API often involves a `Secp256k1` parameter, when users enable the
`global-context` feature they must then pass `SECP256K1` into these
functions. This is kind of clunky since the global is by definition
available everywhere.
Make the API more ergonomic for `global-context` builds by adding
various API functions/methods that use the global context implicitly.
Recently we introduced uniform styling for module docs over in
`rust-bitcoin` repo. We can do the same here but its a bit controversial
because it removes the heading from module docs and every single public
module in rust-secp256k1 uses a heading. Instead we use a full
sentences. Also makes uniform the trailing `//!`.

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.
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.
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`.
This documents the Cargo features making sure docs.rs shows warning for
feature-gated items. They are also explicitly spelled out in the crate
documentation.
With the introduction of Schnorr signatures, exporting a `Signature`
type without any further qualification is ambiguous. To minimize the
ambiguity, the `ecdsa` module is public which should encourage users
to refer to its types as `ecdsa::Signature` and `ecdsa::SerializedSignature`.
To reduce ambiguity in the APIs on `Secp256k1`, we deprecate several
fucntions and introduce new variants that explicitly mention the use of
the ECDSA signature algorithm.
Due to the move of `Signature` and `SerializedSignature` to a new module,
this patch is a breaking change. The impact is minimal though and fixing the
compile errors encourages a qualified naming of the type.
