We do not need serde/std, only serde/alloc. Serde/std breaks no-std
builds, but serde/alloc does not. Depending on serde/alloc is the more
compatible approach, as the entire library already depends on alloc.
Update our `rust-secp256k1` dependency to the latest version.
Requires doing:
- Add a new variant to `Error` for the case where parity of the internal
key is an invalid value (not 0 or 1).
- Use non-deprecated const

Pull request description:
In the first two commits I moved some data from source files to the newly introduced `test_data` dir, including it with `include_[str|bytes]!` macro.
The second-to-last commit introduces a big block in test_data which is very handy in ser/de benchmark (I used it for #672) because with smaller blocks you may not notice performance improvements.
Since I don't want to pollute the package the last commit excludes the `test_data` dir from the published package. I think it's fine to do it because dependent packages don't run dependencies tests.

This documents cargo features in two ways: explictly in text and in code
using `#[doc(cfg(...))]` attribute where possible. Notably, this is
impossible for `serde` derives. The attribute is contitional and only
activated for docs.rs or explicit local builds.
This change also adds `package.metadata.docs.rs` field to `Cargo.toml`
which instructs docs.rs to build with relevant features and with
`docsrs` config activated enabling `#[doc(cfg(...))] attributes.
I also took the opportunity to fix a few missing spaces in nearby code.
Based on the original work by Justin Moon.
*MSRV unchanged from 1.29.0.*
When `std` is off, `no-std` must be on, and we use the [`alloc`](https://doc.rust-lang.org/alloc/) and core2 crates. The `alloc` crate requires the user define a global allocator.
* Import from `core` and `alloc` instead of `std`
* `alloc` only used if `no-std` is on
* Create `std` feature
* Create `no-std` feature which adds a core2 dependency to polyfill `std::io` features. This is an experimental feature and should be
used with caution.
* CI runs tests `no-std`
* MSRV for `no-std` is 1.51 or so
Enabling this feature in the dependency declaration defeats the point
of exposing a feature in rust-bitcoin that enables this because
cargo currently does not provide a way to disable a once activated feature.
Taking an external dependency just to convert ints to byte arrays
is somewhat of a waste, especially when Rust isn't very aggressive
about doing cross-crate LTO.
Note that the latest LLVM pattern-matches this, and while I haven't
tested it, that should mean this means no loss of optimization.
