769a1d9b6c Fix single_char_pattern for \n, \t, etc.
Single characters that are escaped weren't being searched / replaced
correctly in the hint string, so it was saying to replace, say,
`"\n"` with `"\n"` rather than `'\n'`.

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.

Fix span so it no longer contains the whole train-wreck of code and only
points to the problem function (for the unwrap_or lint).

span is now shorter

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
