Fix#27722Fix#27357Fix#25837
1. Fix the typo `BlockingByDependenciesNotPermitted`, which causes the
`not permitted message` not to show. The correct one is `Blocking` or
`BlockedBy`
2. Rewrite the perm check. The perm check uses a very tricky way to
avoid duplicate checks for a slice of issues, which is confusing. In
fact, it's also the reason causing the bug. It uses `lastRepoID` and
`lastPerm` to avoid duplicate checks, but forgets to assign the
`lastPerm` at the end of the code block. So I rewrote this to avoid this
trick.

3. It also reuses the `blocks` slice, which is even more confusing. So I
rewrote this too.

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