58459abd0c Allow pass by reference if we return a reference
Currently this code will trigger `trivally_copy_pass_by_ref`:

```
struct OuterStruct {
    field: [u8; 8],
}

fn return_inner(outer: &OuterStruct) -> &[u8] {
    &outer.field
}
```

If we change the `outer` to be pass-by-value it will not live long
enough for us to return the reference. The above example is trivial but
I've hit this in real code that either returns a reference to either the
argument or in to `self`.

This suppresses the `trivally_copy_pass_by_ref` lint if we return a
reference and it has the same lifetime as the argument. This will likely
miss complex cases with multiple lifetimes bounded by each other but it
should cover the majority of cases with little effort.

Bruno Kirschner
fedd3ef711 Allows neg_cmp_op_on_partial_ord for external macros (fixes #2856).
The macro always negates the result of the given comparison in its
internal check which automatically triggered the lint. As its an
external macro there was no chance to do anything about it which lead
to a white listing of all external macros to prevent further issues.

Removing lint for constant usize array indexing
This commit removes the logic in this PR that linted out-of-bounds constant `usize` indexing on arrays. That case is already handled by rustc's `const_err` lint. Beyond removing the linting logic, the test file and its associated stderr were updated to verify that const `usize` indexing operations on arrays are no longer handled by this `indexing_slicing` lint.

Add tests that index with a const value.
In this commit tests were added to ensure that tests with a `const` index behaved as expected.
In order to minimize the changes to the test's corresponding `stderr`, the tests were appended to
the end of the file.

Revisiting indexing_slicing test cases
This commit contains a few changes. In an attempt to clarify which test cases should and should not produce stderr it became clear that some cases were being handled incorrectly. In order to address these test cases, a minor re-factor was made to the linting logic itself.

The re-factor was driven by edge case handling including a need for additional match conditions for `ExprCall` (`&x[0..=4]`) and `ExprBinary` (`x[1 << 3]`). Rather than attempt to account for each potential `Expr*` the code was re-factored into simply "if ranged index" and an "otherwise" conditions.

Second pass at addressing changes requested
The changes reflected in this commit (requested in PR #2790) are as follows:

- Extended `INDEXING_SLICING` documentation to include the array type so that it is clearer when indexing operations are allowed.
- Variable `ty` defined identically in multiple scopes was moved to an outer scope so it's only defined once.
- Added a missing return statement to ensure only one lint is triggered by a scenario.
- Prettified match statement with a `let` clause. (I learned something new!)
- Added `&x[5..].iter().map(|x| 2 * x).collect::<Vec<i32>>()` and `&x[2..].iter().map(|x| 2 * x).collect::<Vec<i32>>()` to the test cases. The first _should trigger the lint/stderr_ and the second _should not_.

This commit represents an attempt to address changes requested in the process of reviewing PR #2790.
The changes reflected in this commit are as follows:

- Revised `IndexingSlicingPass` struct name to IndexingSlicing for consistency with the rest of the code base.
- Revised match arm condition to use `(..)` shorthand in favor of `(_, _, _)`.
- Restored a couple telling variable names.
- Calls to `cx.span_lint` were revised to use `utils::span_help_and_lint`.
- Took a stab at refactoring some generalizable calls to `utils::span_help_and_lint` to minimize duplicate code.
- Revised INDEXING_SLICING declaration to pedantic rather than restriction.
- Added `&x[0..].get(..3)` to the test cases.

Rename instances of array_indexing
This commit renames instances of `array_indexing` to `indexing_slicing` and moves the `indexing_slicing` lint to the `clippy_pedantic` group. The justification for this commit's changes are detailed in the previous commit's message.

Extend indexing_slicing lint
Hey there clippy team! I've made some assumptions in this PR and I'm not at all certain they'll look like the right approach to you. I'm looking forward to any feedback or revision requests you have, thanks!

    Prior to this commit the `indexing_slicing` lint was limited to indexing/slicing operations on arrays. This meant that the scope of a really useful lint didn't include vectors. In order to include vectors in the `indexing_slicing` lint a few steps were taken.

    The `array_indexing.rs` source file in `clippy_lints` was renamed to `indexing_slicing.rs` to more accurately reflect the lint's new scope. The `OUT_OF_BOUNDS_INDEXING` lint persists through these changes so if we can know that a constant index or slice on an array is in bounds no lint is triggered.

    The `array_indexing` tests in the `tests/ui` directory were also extended and moved to `indexing_slicing.rs` and `indexing_slicing.stderr`.

    The `indexing_slicing` lint was moved to the `clippy_pedantic` lint group.

    A specific "Consider using" string was added to each of the `indexing_slicing` lint reports.

    At least one of the test scenarios might look peculiar and I'll leave it up to y'all to decide if it's palatable. It's the result of indexing the array `x` after `let x = [1, 2, 3, 4];`

    ```
    error: slicing may panic. Consider using `.get(..n)`or `.get_mut(..n)`instead
      --> $DIR/indexing_slicing.rs:23:6
       |
    23 |     &x[0..][..3];
       |      ^^^^^^^^^^^
    ```

    The error string reports only on the second half's range-to, because the range-from is in bounds!

    Again, thanks for taking a look.

    Closes #2536

This checks for things like

which should be written using `if let` or `match` instead.

mutated in an expression to utils/usage.rs.

Fix useless_format false positive with macros
Clippy was issuing a warning when `format!` was used inside a macro.
That's a problem because macros have different syntax and can be outside
the control of the user.

This skips the `useless_format` check if the `format!` call is inside a
macro.

Fix false positive in empty_line_after_outer_attr
Before, when you had a block comment between an attribute and the
following item like this:

```rust
\#[crate_type = "lib"]
/*

*/
pub struct Rust;
```

It would cause a false positive on the lint, because there is an empty
line inside the block comment.

This makes sure that basic block comments are detected and removed from
the snippet that was created before.

Fix false positive in empty_line_after_outer_attribute
`empty_line_after_outer_attribute` produced a false positive warning when
deriving `Copy` and/or `Clone` for an item.

It looks like the second point in [this comment][that_comment] is related,
as the attribute that causes the false positive has a path of
`rustc_copy_clone_marker`.

Fixes #2475

8494f57c82 Fix author lint
The author lint was generating invalid code as shown on issue:
https://github.com/rust-lang-nursery/rust-clippy/issues/2442

I've changed the generated code to properly track cast
expressions.

Unfortunatelly, I've had to rewrite the `visit_decl` method, to
avoid that last if of the chain will be added. After looking at the code,
this last line was being added because of the `let x: char` part, but not
because of the `0x45df as char` expression.

It seems that let statements should not generate code on the author
lint, but I'm not sure that this is true or if I'm breaking
something on other code generation parts.

Finally, I've added a test for the author lint, but I'm not sure that
this needs to be added to the testsuite.

Lint multiline attributes properly
This makes it so that the `empty_line_after_outer_attribute` lint only
checks for newlines between the end of the attribute and the beginning
of the following item.

We need to check for the empty line count being bigger than 2 because
now the snippet of valid code contains only `\n` and splitting it
produces `["", ""]`
Invalid code will contain more than 2 empty strings.

Partly fix incorrect useless_attribute suggestion
This fixes an incorrect suggestion from the `useless_attribute` lint
when using `cfg_attr`.

Additionally, it will not show a suggestion anymore, if the attribute
begins on a previous line, because it is much harder to construct the
span of multi-line `cfg_attr` attributes as they don't appear in the AST.

To fix it completely, one would have to parse upwards into the file,
and find the beginning of the `cfg_attr` attribute.

Fix false positive in empty_line_after_outer_attr
Doc comments are syntactic sugar for #[doc] attributes, so this lint was
catching them, too.

This commit makes it so that doc comments are ignored in this lint.

I think, for normal attributes it makes sense to warn about following empty
lines, for doc comments, less. This way the user has some freedom over
the formatting.

7467b83377 Suggest removing inline attributes
This adds a `suggest_remove_item` helper that will remove an item and
all trailing whitespace. This should handle both attributes on the same
line as the function and on a separate line; the function takes the
position of the original attribute.

5f3c340bfb Lint for trait methods without bodies
As discussed in rust-lang/rust#47475 the #[inline] attribute is
currently allowed on trait methods without bodies (i.e. without a
default implementation). This is misleading as it could be interpreted
as affecting the implementations of the trait method. Add a lint for any
use of #[inline] on a trait method without a body.

Fixes rust-lang/rust#47475
