* Gracefully shutdown after rejecting to hopefully fix the errors on windows

In #461 I missed that these options are not stable so it breaks our CI. This PR reverts that change while keeping the whitespace changes from #461.

Apologies for the noise.

Similar to #435 that adds the same restrictions to subscriptions too.
To avoid having faulty trait bounds on when the subcription actually returns Result.

* More tweaks

* Move proc macro code out of the "new" folder

* fmt

* Can't add doc-links to dev-dependencies

* rewrite me

* require proc macro API to return result

* send unknown message when error is not CallError

* show example that auto cast StdError doesn't work

* clippy

* replace generic errors with anyhow::Error

* fix nits

* example that anyhow::Error in register_method works

* CallError: add missing From impl

* [types]: add helper methods for Error types

The rationale is to make it possible for users to either use anyhow::Error or use the helper methods.

* fmt

* Revert "register_*_method Into<Error>"

This reverts commit 33b4fa28730b72647ba150659d3c0ab1937e524a.

Also, rework the way we return errors: prefer JSON-RPC errors according to spec (application/json) wherever sensible.

However, `hyper 13` is not fixed but I think we should remove that support anyway?!

* fix(ws client): use query part of URL.

Fixes #428, we didn't take that query part of the URL into account and it wasn't sent in GET request.
