Allowing only single fork per user/organization

[lafriks]

I think we should allow only single fork for every user/organization from single repository. At least I don't see point of having multiple forks for each user and PR anyway does not work with multiple forks for one user because of url limitation. It could be also source of bad practice that users are creating new forks just for PR instead of normal workflow with new branches.

GitHub also does allow only single fork, just as GitLab.

If that's seem ok, I could create PR for this.

Does this also make it impossible for an individual user to fork a project to multiple organizations?

I described a scenario where that is needed at gogs/gogs#1791 (comment), switched to Gitea because it implemented the feature as noted by @lunny at gogs/gogs#1791 (comment), and am currently using it.
