Fix syntax highlighting of code fence 
The documentation for RESULT_EXPECT_USED includes this code:

    let res: Result<usize, ()> = Ok(1);
    res?;
    # Ok::<(), ()>(())

Because the code fence didn't start with `rust`, the code wasn't highlighted and the line starting with `#` was displayed on the website. This is now fixed.

Move project_root function to clippy_dev/src/lib.rs 
This allows us to use the method in both `fmt.rs` and `lib.rs` in
multiple places. The downside is that we panic inside the method now,
instead of using the error handling in `fmt.rs`. We may want to
centralize the error handling for clippy_dev at some point, though.

Deprecate util/dev in favor of cargo alias 
If you've been using `./util/dev` before, this now becomes `cargo dev`.

The key part of this change is found in `.cargo/config`.

This means one less shell script and a bit more cross-platform support
for contributors.

Closes #4399
changelog: dont fire `possible_missing_comma` if intendation is present

I suspect there is already a utils function for indentation (but searching indent didn't yield a function for that), and my solution is certainly not universal, but it's probably the best we can do.

add size parameter for `vec_box`  lint

changelog: add size threshold for the `vec_box` lint, currently 4096 bytes (one page) (subject to change). Closes #3547.

diff is a little bit confusing due to some refactoring (moving free functions to lint struct functions), relevant portion is [this](https://github.com/rust-lang/rust-clippy/compare/master...Areredify:vec_box_threshold?expand=1#diff-1096120ca9143af89dcc9175ea92b54aR294-R298). In hindsight should've been different commits, but oh well.
