Set the LastModified header for raw files (#18356)
Although the use of LastModified dates for caching of git objects should be
discouraged (as it is not native to git - and there are a LOT of ways this
could be incorrect) - LastModified dates can be a helpful somewhat more human
way of caching for simple cases.

This PR adds this header and handles the If-Modified-Since header to the /raw/
routes.

Fix #18354

Add API to query collaborators permission for a repository (#18761)
Targeting #14936, #15332

Adds a collaborator permissions API endpoint according to GitHub API: https://docs.github.com/en/rest/collaborators/collaborators#get-repository-permissions-for-a-user to retrieve a collaborators permissions for a specific repository.

### Checks the repository permissions of a collaborator. 

`GET` `/repos/{owner}/{repo}/collaborators/{collaborator}/permission`

Possible `permission` values are `admin`, `write`, `read`, `owner`, `none`.

```json
{
  "permission": "admin",
  "role_name": "admin",
  "user": {}
}
```

Where `permission` and `role_name` hold the same `permission` value and `user` is filled with the user API object. Only admins are allowed to use this API endpoint.

Add "Allow edits from maintainer" feature (#18002)
Adds a feature [like GitHub has](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request-from-a-fork) (step 7).
If you create a new PR from a forked repo, you can select (and change later, but only if you are the PR creator/poster) the "Allow edits from maintainers" option.
Then users with write access to the base branch get more permissions on this branch:
* use the update pull request button
* push directly from the command line (`git push`)
* edit/delete/upload files via web UI
* use related API endpoints

You can't merge PRs to this branch with this enabled, you'll need "full" code write permissions.

This feature has a pretty big impact on the permission system. I might forgot changing some things or didn't find security vulnerabilities. In this case, please leave a review or comment on this PR.

Closes #17728

Improve dashboard's repo list performance (#18963)
* Improve dashboard's repo list performance

- Avoid a lot of database lookups for all the repo's, by adding a
undocumented "minimal" mode for this specific task, which returns the
data that's only needed by this list which doesn't require any database
lookups.
- Makes fetching these list faster.
- Less CPU overhead when a user visits home page.

* Refactor javascript code + fix Fork icon

- Use async in the function so we can use `await`.
- Remove `archivedFilter` check for count, as it doesn't make sense to
  show the count of repos when you can't even see them(as they are
  filited away).

* Add `count_only`

* Remove uncessary code

* Improve comment

Never use /api/v1 from Gitea UI Pages (#19318)
Reusing `/api/v1` from Gitea UI Pages have pros and cons.
Pros:
1) Less code copy

Cons:
1) API/v1 have to support shared session with page requests.
2) You need to consider for each other when you want to change something about api/v1 or page.

This PR moves all dependencies to API/v1 from UI Pages.

Fix the bug: deploy key with write access can not push (#19010)
Use DeployKeyID to replace the IsDeployKey, then CanWriteCode uses the DeployKeyID to check the write permission.

Add apply-patch, basic revert and cherry-pick functionality (#17902)
This code adds a simple endpoint to apply patches to repositories and
branches on gitea. This is then used along with the conflicting checking
code in #18004 to provide a basic implementation of cherry-pick revert.

Now because the buttons necessary for cherry-pick and revert have 
required us to create a dropdown next to the Browse Source button
I've also implemented Create Branch and Create Tag operations.

Fix #3880 
Fix #17986
