Enable more revive linter rules (#30608)
Noteable additions:

- `redefines-builtin-id` forbid variable names that shadow go builtins
- `empty-lines` remove unnecessary empty lines that `gofumpt` does not
remove for some reason
- `superfluous-else` eliminate more superfluous `else` branches

Rules are also sorted alphabetically and I cleaned up various parts of
`.golangci.yml`.

Use raw Wiki links for non-renderable Wiki files (#30273)
In Wiki pages, short-links created to local Wiki files were always
expanded as regular Wiki Links. In particular, if a link wanted to point
to a file that Gitea doesn't know how to render (e.g, a .zip file), a
user following the link would be silently redirected to the Wiki's home
page.

This change makes short-links* in Wiki pages be expanded to raw wiki
links, so these local wiki files may be accessed without manually
accessing their URL.

* only short-links ending in a file extension that isn't renderable are
affected.

Closes #27121.

Fixes #27605: inline math blocks can't be preceeded/followed by alphanumerical characters (#30175)
- Inline math blocks couldn't be preceeded or succeeded by
alphanumerical characters due to changes introduced in PR #21171.
Removed the condition that caused this (precedingCharacter condition)
and added a new exit condition of the for-loop that checks if a specific
'$' was escaped using '\' so that the math expression can be rendered as
intended.
- Additionally this PR fixes another bug where math blocks of the type
'$xyz$abc$' where the dollar sign was not escaped by the user, generated
an error (shown in the screenshots below)
- Altered the tests to accomodate for the changes

Former behaviour (from try.gitea.io):

Don't use <br /> in alert block (#29650)
- Follows https://github.com/go-gitea/gitea/pull/29121

When I implemented alert blocks I was always testing the markdown in
issue comments. I used `<br />` for line breaks and it looked good. I
have since learned that the markdown on README files doesn't allow these
tags. So a comment with

```md
> [!NOTE]
> If you're interested in using our APIs, we have experimental support with [documentation](https://try.gitea.io/api/swagger).
```

looked like this in a comment

![image](https://github.com/go-gitea/gitea/assets/20454870/96b1de01-2c87-4d4f-83dd-98192b83e9d0)
but looked like this in a README

![image](https://github.com/go-gitea/gitea/assets/20454870/474b636d-dd7a-4b7f-ba27-643803c71aa3)

So I changed how we render the alert block by having the alert itself
have a dedicated paragraph, so line breaks happen naturally between
paragraphs.

Refactor some Str2html code (#29397)
This PR touches the most interesting part of the "template refactoring".

1. Unclear variable type. Especially for "web/feed/convert.go":
sometimes it uses text, sometimes it uses HTML.
2. Assign text content to "RenderedContent" field, for example: `
project.RenderedContent = project.Description` in web/org/projects.go
3. Assign rendered content to text field, for example: `r.Note =
rendered content` in web/repo/release.go
4. (possible) Incorrectly calling `{{Str2html
.PackageDescriptor.Metadata.ReleaseNotes}}` in
package/content/nuget.tmpl, I guess the name Str2html misleads
developers to use it to "render string to html", but it only sanitizes.
if ReleaseNotes really contains HTML, then this is not a problem.

Rework markup link rendering (#26745)
Fixes #26548

This PR refactors the rendering of markup links. The old code uses
`strings.Replace` to change some urls while the new code uses more
context to decide which link should be generated.

The added tests should ensure the same output for the old and new
behaviour (besides the bug).

We may need to refactor the rendering a bit more to make it clear how
the different helper methods render the input string. There are lots of
options (resolve links / images / mentions / git hashes / emojis / ...)
but you don't really know what helper uses which options. For example,
we currently support images in the user description which should not be
allowed I think:

<details>
  <summary>Profile</summary>

Make cross-reference issue links work in markdown documents again (#28682)
In #26365 issue references were disabled entirely for documents,
intending to match GitHub behavior. However cross-references do appear
to work in documents on GitHub.

This is useful for example to write release notes in a markdown document
and reference issues. While the simpler syntax may create links when not
intended, hopefully the cross-reference syntax is unique enough to avoid
it.

Remove title from elements on Org mode (#27968)
The Org mode rendering has some problems:
1.  `[[https://example.com][pre https://example.com/example.mp4 post]]`
 renders as
`<p><a href="https://example.com" title="pre <video
src="https://example.com/example.mp4"
title="https://example.com/example.mp4">https://example.com/example.mp4</video>
post">pre <video src="https://example.com/example.mp4"
title="https://example.com/example.mp4">https://example.com/example.mp4</video>
post</a></p>`
As you can see, the `title` attribute contains the inner html in
unescaped form. I removed the `title` attribute because it is of little
value.
3. The `title` attribute on `img` and `video` is of little value.
4. The inner elements of `video` are different depending on the `if`.

Do not highlight #number in documents (#26365)
- Currently the post processing will transform all issue indexes (such as `#6`) into a clickable link.
- This makes sense in an situation like issues or PRs,
where referencing to other issues is quite common
and only referencing their issue index is an handy and efficient way to do it.
- Currently this is also run for documents
(which is the user profile and viewing rendered files),
but in those situations it's less common to reference issues by their index and instead could mean something else.
- This patch disables this post processing for issue index for documents. Matches Github's behavior.
- Added unit tests.

work) url schemes even if all other schemes are allowed
- Fixed older `cbthunderlink` tests

Replace interface{} with any (#25686)
Result of running `perl -p -i -e 's#interface\{\}#any#g' **/*` and `make fmt`.

Basically the same [as golang did](2580d0e08d).

Refactor path & config system (#25330)
# The problem

There were many "path tricks":

* By default, Gitea uses its program directory as its work path
* Gitea tries to use the "work path" to guess its "custom path" and
"custom conf (app.ini)"
* Users might want to use other directories as work path
* The non-default work path should be passed to Gitea by GITEA_WORK_DIR
or "--work-path"
* But some Gitea processes are started without these values
    * The "serv" process started by OpenSSH server
    * The CLI sub-commands started by site admin
* The paths are guessed by SetCustomPathAndConf again and again
* The default values of "work path / custom path / custom conf" can be
changed when compiling

# The solution

* Use `InitWorkPathAndCommonConfig` to handle these path tricks, and use
test code to cover its behaviors.
* When Gitea's web server runs, write the WORK_PATH to "app.ini", this
value must be the most correct one, because if this value is not right,
users would find that the web UI doesn't work and then they should be
able to fix it.
* Then all other sub-commands can use the WORK_PATH in app.ini to
initialize their paths.
* By the way, when Gitea starts for git protocol, it shouldn't output
any log, otherwise the git protocol gets broken and client blocks
forever.

The "work path" priority is: WORK_PATH in app.ini > cmd arg --work-path
> env var GITEA_WORK_DIR > builtin default

The "app.ini" searching order is: cmd arg --config > cmd arg "work path
/ custom path" > env var "work path / custom path" > builtin default


## ⚠️ BREAKING

If your instance's "work path / custom path / custom conf" doesn't meet
the requirements (eg: work path must be absolute), Gitea will report a
fatal error and exit. You need to set these values according to the
error log.
