Add support for triggering webhook notifications on wiki changes.
This PR contains frontend and backend for webhook notifications on wiki actions (create a new page, rename a page, edit a page and delete a page). The frontend got a new checkbox under the Custom Event -> Repository Events section. There is only one checkbox for create/edit/rename/delete actions, because it makes no sense to separate it and others like releases or packages follow the same schema.

The actions itself are separated, so that different notifications will be executed (with the "action" field). All the webhook receivers implement the new interface method (Wiki) and the corresponding tests.
When implementing this, I encounter a little bug on editing a wiki page. Creating and editing a wiki page is technically the same action and will be handled by the ```updateWikiPage``` function. But the function need to know if it is a new wiki page or just a change. This distinction is done by the ```action``` parameter, but this will not be sent by the frontend (on form submit). This PR will fix this by adding the ```action``` parameter with the values ```_new``` or ```_edit```, which will be used by the ```updateWikiPage``` function.
I've done integration tests with matrix and gitea (http).

`login_name` (Authentication Sign-in Name) is not included in the response of `adminUserCreate` API.
This PR is to return user-specified `login_name` if there is one.
`PATCH /repos/{owner}/{repo}` API allows users to update `allow_rebase_update`, `default_delete_branch_after_merge`, but `GET /repos/{owner}/{repo}` API does not return these two options, and API users has no other ways to find the state of these two options.
This PR add `allow_rebase_update`, `default_delete_branch_after_merge` to repository query api response.

* Make sure API responses always refer to username in original case
Copied from what I wrote on #19133 discussion: Handling username case is a very tricky issue and I've already encountered a Mastodon <-> Gitea federation bug due to Gitea considering Ta180m and ta180m to be the same user while Mastodon thinks they are two different users. I think the best way forward is for Gitea to only use the original case version of the username for federation so other AP software don't get confused.
* Move httpsig algs constant slice to modules/setting/federation.go
* Add new federation settings to app.example.ini and config-cheat-sheet
* Return if marshalling error
* Make sure Person IRIs are generated correctly
This commit ensures that if the setting.AppURL is something like "http://127.0.0.1:42567" (like in the integration tests), a trailing slash will be added after that URL.
* If httpsig verification fails, fix Host header and try again
This fixes a very rare bug when Gitea and another AP server (confirmed to happen with Mastodon) are running on the same machine, Gitea fails to verify incoming HTTP signatures. This is because the other AP server creates the sig with the public Gitea domain as the Host. However, when Gitea receives the request, the Host header is instead localhost, so the signature verification fails. Manually changing the host header to the correct value and trying the veification again fixes the bug.
* Revert "If httpsig verification fails, fix Host header and try again"
This reverts commit f53e46c721a037c55facb9200106a6b491bf834c.
The bug was actually caused by nginx messing up the Host header when reverse-proxying since I didn't have the line `proxy_set_header Host $host;` in my nginx config for Gitea.

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.
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

We can't depend on `latest` version of gofumpt because the output will
not be stable across versions. Lock it down to the latest version
released yesterday and run it again.
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.

integrations: basic test for Gitea {dump,restore}-repo
This is a first step for integration testing of DumpRepository and
RestoreRepository. It:
runs a Gitea server,
dumps a repo via DumpRepository to the filesystem,
restores the repo via RestoreRepository from the filesystem,
dumps the restored repository to the filesystem,
compares the first and second dump and expects them to be identical
The verification is trivial and the goal is to add more tests for each
topic of the dump.

There is no public usable instance so no integration tests added.
Nodeinfo is a way to expose certain metadata about a server for use of discovery regarding functionality of its federation capabilities.
Two endpoints are required:
1. `/.well-known/nodeinfo` which informs client where it can find the location of the location of its metadata (including which version of the schema is used)
2. the endpoint which exposes the metadata in json format according to schema.
Notes:
* `openRegistrations` is a required field, but I propose to set to false as default in case someone writes a crawler to discover "open" gitea instances
* to limit data leakage I also propose to not include the `usage` field (note it is required so it should be included, but left as empty).

Fixes #16381
Note that changes to unprotected files via the web editor still cannot be pushed directly to the protected branch. I could easily add such support for edits and deletes if needed. But for adding, uploading or renaming unprotected files, it is not trivial.

* Add LRU mem cache implementation (#16226)
The current default memory cache implementation is unbounded in size and number of
objects cached. This is hardly ideal.
This PR proposes creating a TwoQueue LRU cache as the underlying cache for Gitea.
The cache is limited by the number of objects stored in the cache (rather than size)
for simplicity. The default number of objects is 50000 - which is perhaps too small
as most of our objects cached are going to be much less than 1kB.
It may be worth considering using a different LRU implementation that actively limits
sizes or avoids GC - however, this is just a beginning implementation.
