Most middleware throw a 404 in case something is not found e.g. a Repo
that is not existing. But most API endpoints don't include the 404
response in their documentation. This PR changes this.
To avoid deadlock problem, almost database related functions should be
have ctx as the first parameter.
This PR do a refactor for some of these functions.
Adds API endpoints to manage issue/PR dependencies
* `GET /repos/{owner}/{repo}/issues/{index}/blocks` List issues that are
blocked by this issue
* `POST /repos/{owner}/{repo}/issues/{index}/blocks` Block the issue
given in the body by the issue in path
* `DELETE /repos/{owner}/{repo}/issues/{index}/blocks` Unblock the issue
given in the body by the issue in path
* `GET /repos/{owner}/{repo}/issues/{index}/dependencies` List an
issue's dependencies
* `POST /repos/{owner}/{repo}/issues/{index}/dependencies` Create a new

* `DELETE /repos/{owner}/{repo}/issues/{index}/dependencies` Remove an
