Fix clippy build failure
Clippy build fails because the feature `result_map_or` has been stabilized in v1.41.0 but we still have an explicit feature attribute for it.

Fix false positive with cast_sign_loss lint
`cast_sign_loss` lint incorrectly suggests that the result of `checked_abs`, `rem_euclid` and `checked_rem_euclid` cannot be casted to an unsigned integer without loss.
Fixes#4818#4764#4743
changelog: Fix false positives in `cast_sign_loss` lint
Add lint to detect transmutes from float to integer
Add lint that detects transmutation from a float to an integer and suggests usage of `{f32, f64}.to_bits()` instead.
Fixes#3993
changelog: Add lint `transmute_float_to_int`
Add lint for pub fns returning a `Result` without documenting errors
The Rust Book recommends that functions that return a `Result` type have [a doc comment with an `# Errors` section](https://doc.rust-lang.org/book/ch14-02-publishing-to-crates-io.html#commonly-used-sections) describing the kind of errors that can be returned. This change adds a lint to enforce this. The lint is allow by default; it can be enabled with `#![warn(clippy::missing_errors_doc)]`.
Closes#4854.
changelog: adds lint for `missing_errors_doc`
The Rust Book recommends that functions that return a `Result` type have
a doc comment with an `# Errors` section describing the kind of errors
that can be returned
(https://doc.rust-lang.org/book/ch14-02-publishing-to-crates-io.html#commonly-used-sections).
This change adds a lint to enforce this. The lint is allow by default;
it can be enabled with `#![warn(clippy::missing_errors_doc)]`.
Closes#4854.
`cast_sign_loss` lint incorrectly suggests that the result of
`checked_abs`, `rem_euclid` and `checked_rem_euclid` cannot
be casted to an unsigned integer without loss.
Fix false positive in `string_add`.
`clippy::string_add` was popping up in macros.
I'm not sure what clippy's general direction is in these matters, but I can change it to be external macros only too.

changelog: Fix false positives for `string_add` in macro expansions.
Rustup to rust-lang/rust#66878
I need to sleep now, feel free to pick it up.
The output of the `lint_without_lint_pass` test seems to disappear, I'm not sure why.. :/

Fix FP in manual_swap lint with slice-like types
Fixes#4853
changelog: Fix FP in [`manual_swap`] lint with slice-like types and make it auto applicable
Less needless_doctest_main false positives
This checks if a) the `fn main() {}` function is empty or if the doctest contains a `static`. In both cases don't lint. While this fixes#4858 at the cost of some false negatives, but this seems a better solution than disabling the lint outright. In the long run, using `syn` should solve the issue in the right way.

Fix master deployment
It was failing because it could not find `.github/deploy_key.enc` in the
current directory (`./out`). Switching to the previous directory should
fix the deployment and the master build.
