Instead of providing a mechanism for users to opt out of randomization
we can just feature gate the call site i.e., opportunistically randomize
the global context on creation if `rand-std` feature is enabled.
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.
314e8755df Clarify `global-context` feature (Martin Habovstiak)
d52ab85dd5 Added missing features to docs.rs config (Martin Habovstiak)
Pull request description:
Sadly, I missed two details in #353: features missing in docs.rs configuration and `global-context` being a bit confusing.
This PR fixes those, see commit messages for details.

Pull request description:
(Candidate for most trivial patch of all time.)
Seems to be a typo, change the 'L' to an 'l'.

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.
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
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.
