Roadmap for 2021
[Rendered](https://github.com/flip1995/rust-clippy/blob/roadmap/doc/roadmap-2021.md)
This is the first time Clippy gets its own roadmap. The reason for this roadmap is, that with the Rust language growing, also Clippy is growing. With this keeping track of and implementing bigger projects gets quite hard. This roadmap should help in exactly this regard.
After having the approval of this roadmap by the Clippy team, we want to know from the community:
- What do you think in general about this roadmap?
- Are there any pain points in Clippy, that should be included here?
- What of the points listed here has the highest priority for you?
We're looking forward to getting your feedback!
changelog: Add roadmap for Clippy 2021
r? `@rust-lang/clippy`
This changes the variable used for testing Clippy in the internal test
suite:
```
CLIPPY_TESTS -> __CLIPPY_INTERNAL_TESTS
```
`CLIPPY_TESTS` is understandably used in environments of Clippy users,
so we shouldn't use it in our test suite.
📌 Pin Clippy to a nightly 📌
changelog: Pin Clippy to a specific nightly version (No more master/custom toolchain required to compile Clippy)
Addresses partially #5561. As proposed there in [this comment](https://github.com/rust-lang/rust-clippy/issues/5561#issuecomment-623109095), this kicks off the process, to help us get acquainted with how the syncs should work, before working on improving the tooling.
Open questions:
* When performing a rustup, we will need to exclude the commits that were merged that same day, or else wait until that nightly is released. I did not update the documentation about this part, mainly because I'm not sure about how to do that.
* When should we perform the rustups now? My first idea is to do it at the same time we do the clippyups, to have a clear cadence and to avoid the two copies of the repo to diverge enough to make the process painful.
* Who does the rustups now? If we follow my previous idea and do both rustup and clippyup at the same time, it would be more work for `@flip1995` who currently does the clippyups. I would prefer to establish some kind of rotation to spead the work. Other ideas?
* I'm not sure if this affects the release process in any way.
* ???
`@rust-lang/clippy` thoughts?

Add more infomation about LintStore registration
Backstory: I somehow missed the fact that I needed to register a lint pass in order for it to run, and I spent some time confused until I figured it out. So I wanted to make it clear that a missing `register_(early|late)_pass` call is a likely cause of a lint not running.
changelog: none
Suggest a compatible shell for setup-toolchain.sh
setup-toolchain.sh uses "[[" which is a bash builtin, but the guide
suggests running it with sh. On Ubuntu, /bin/sh points to dash and
running the script fails.

Update release documentation
When updating the beta branch, we want to reset, instead of rebase. Otherwise we might produce again new commits on the beta branch, that aren't on the master branch.
changelog: none
Rename tables to typecheck_result()
While working on #6130, I noticed that part of the documentation was updated to use `LateContext::typeck_results`, but the paragraph still referred to the old `tables` field of `LateContext`.

Clippy dev subcommand to build and serve website
This PR adds `clippy dev serve` which will pop open a browser with a local rendered 'ALL the Clippy Lints' website, and re-render as you edit stuff.

changelog: none
* Add an easy-to-see note at the top of `CONTRIBUTING.md` that points
new contributors to the Basics docs
* Add a note about compiler errors as a result of internals changes
that break Clippy
Update the changelog update documentation
I just started working on updating the changelog. Hopefully the docs are a bit clearer now?
