Refactor the setting to make unit test easier (#22405)
Some bugs caused by less unit tests in fundamental packages. This PR
refactor `setting` package so that create a unit test will be easier
than before.

- All `LoadFromXXX` files has been splited as two functions, one is
`InitProviderFromXXX` and `LoadCommonSettings`. The first functions will
only include the code to create or new a ini file. The second function
will load common settings.
- It also renames all functions in setting from `newXXXService` to
`loadXXXSetting` or `loadXXXFrom` to make the function name less
confusing.
- Move `XORMLog` to `SQLLog` because it's a better name for that.

Maybe we should finally move these `loadXXXSetting` into the `XXXInit`
function? Any idea?

Add more linters to improve code readability (#19989)
Add nakedret, unconvert, wastedassign, stylecheck and nolintlint linters to improve code readability

- nakedret - https://github.com/alexkohler/nakedret - nakedret is a Go static analysis tool to find naked returns in functions greater than a specified function length.
- unconvert - https://github.com/mdempsky/unconvert - Remove unnecessary type conversions
- wastedassign - https://github.com/sanposhiho/wastedassign -  wastedassign finds wasted assignment statements.
- notlintlint -  Reports ill-formed or insufficient nolint directives
- stylecheck - https://staticcheck.io/docs/checks/#ST - keep style consistent
  - excluded: [ST1003 - Poorly chosen identifier](https://staticcheck.io/docs/checks/#ST1003) and [ST1005 - Incorrectly formatted error string](https://staticcheck.io/docs/checks/#ST1005)

User keypairs and HTTP signatures for ActivityPub federation using go-ap (#19133)
* go.mod: add go-fed/{httpsig,activity/pub,activity/streams} dependency

go get github.com/go-fed/activity/streams@master

* Implemented Webfinger endpoint.

* Add visible check.

* Add user profile as alias.

* Add actor IRI and remote interaction URL to WebFinger response

* WebFinger: Add CORS header and fix Href -> Template for remote interactions

The CORS header is needed due to https://datatracker.ietf.org/doc/html/rfc7033#section-5 and fixes some Peertube <-> Gitea federation issues

* make lint-backend

* Make sure Person endpoint has Content-Type application/activity+json and includes PreferredUsername, URL, and Icon

Setting the correct Content-Type is essential for federating with Mastodon

* Use UTC instead of GMT

* Rename pkey to pubKey

* Make sure HTTP request Date in GMT

* make fmt

* dont drop err

* 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 f53e46c721.

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.

* Go back to using ap.IRI to generate inbox and outbox IRIs

* use const for key values

* Update routers/web/webfinger.go

* Use ctx.JSON in Person response to make code cleaner

* Revert "Use ctx.JSON in Person response to make code cleaner"

This doesn't work because the ctx.JSON() function already sends the response out and it's too late to edit the headers.

This reverts commit 95aad98897.

* Use activitypub.ActivityStreamsContentType for Person response Content Type

* Limit maximum ActivityPub request and response sizes to a configurable setting

* Move setting key constants to models/user/setting_keys.go

* Fix failing ActivityPubPerson integration test by checking the correct field for username

* Add a warning about changing settings that can break federation

* Add better comments

* Don't multiply Federation.MaxSize by 1<<20 twice

* Add more better comments

* Fix failing ActivityPubMissingPerson test

We now use ctx.ContextUser so the message printed out when a user does not exist is slightly different

* make generate-swagger

For some reason I didn't realize that /templates/swagger/v1_json.tmpl was machine-generated by make generate-swagger... I've been editing it by hand for three months! 🤦

* Move getting the RFC 2616 time to a separate function

* More code cleanup

* Update go-ap to fix empty liked collection and removed unneeded HTTP headers

* go mod tidy

* Add ed25519 to httpsig algorithms

* Use go-ap/jsonld to add @context and marshal JSON

* Change Gitea user agent from the default to Gitea/Version

* Use ctx.ServerError and remove all remote interaction code from webfinger.go

Federation: return useful statistic information for nodeinfo (#19561)

Add nodeinfo endpoint for federation purposes (#16953)
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).
