Backport #28719 by wxiaoguang

In #26851, it assumed that `Commit` always exists when
`PageIsDiff==true`.

But for a 404 page, the `Commit` doesn't exist, so the following code
would cause panic because nil value can't be passed as string parameter
to `IsMultilineCommitMessage(string)` (or the StringUtils.Cut in later
PRs)

Backport #27384 by @rbhz

Add support for HEAD in paths:
```
/src/branch/HEAD/README.md
/src/commit/HEAD/README.md
```

Closes #26920

Currently 'userxx' and 'orgxx' are both used as username in test files
when the user type is org, which is confusing. This PR replaces all
'userxx' with 'orgxx' when the user type is org(`user.type==1`).
Some non-trivial changes
1. Rename `user3` dir to `org3` in `tests/git-repositories-meta` 
2. Change `end` in `issue reference` because 'org3' is one char shorter
than 'user3'

3. Change the search result number of `user/repo2` because
`user3/repo21` can't be searched now

4. Change the first org name getting from API because the result is
ordered by alphabet asc and now `org 17` is before `org25`

Other modifications are just find all and replace all.
Unit tests with SQLite are all passed.

- The permalink and 'Reference in New issue' URL of an renderable file
(those where you can see the source and a rendered version of it, such
as markdown) doesn't contain `?display=source`. This leads the issue
that the URL doesn't have any effect, as by default the rendered version
is shown and thus not the source.
- Add `?display=source` to the permalink URL and to 'Reference in New
Issue' if it's renderable file.
- Add integration testing.

Make use of the [new
octicon](https://github.com/primer/octicons/issues/945) that indicates a
symlink to a directory:

This fixes up https://github.com/go-gitea/gitea/pull/10446; in that, the
*expected* timezone was changed to the local timezone, but the computed
timezone was left in UTC.

The result was this failure, when run on a non-UTC system:

I assume this was probably missed since the CI servers all run in UTC?

The Format() string "Mon, 02 Jan 2006 15:04:05 UTC" was incorrect: 'UTC'
isn't recognized as a variable placeholder, but was just being copied
verbatim. It should use 'MST' in order to command Format() to output the
attached timezone, which is what `time.RFC1123` has.

Enable [forbidigo](https://github.com/ashanbrown/forbidigo) linter which
forbids print statements. Will check how to integrate this with the
smallest impact possible, so a few `nolint` comments will likely be
required. Plan is to just go through the issues and either:

- Remove the print if it is nonsensical
- Add a `//nolint` directive if it makes sense

I don't plan on investigating the individual issues any further.

- No more flashes of unstyled content around time elements
- These elements are localized using the `lang` property of the HTML file
- Relative (e.g. the activities in the dashboard) and duration (e.g.
server uptime in the admin page) time elements are auto-updated to keep
up with the current time without refreshing the page
- Code that is not needed anymore such as `formatting.js` and parts of `since.go` have been deleted

Replaces #21440
Follows #22861

Follow:
* #23574
* Remove all ".tooltip[data-content=...]"

Major changes:

* Remove "tooltip" class, use "[data-tooltip-content=...]" instead of
".tooltip[data-content=...]"
* Remove legacy `data-position`, it's dead code since last Fomantic
Tooltip -> Tippy Tooltip refactoring
* Rename reaction attribute from `data-content` to
`data-reaction-content`
* Add comments for some `data-content`: `{{/* used by the form */}}`
* Remove empty "ui" class
* Use "text color" for SVG icons (a few)

`namedBlob` turned out to be a poor imitation of a `TreeEntry`. Using
the latter directly shortens this code.

This partially undoes https://github.com/go-gitea/gitea/pull/23152/,
which I found a merge conflict with, and also expands the test it added
to cover the subtle README-in-a-subfolder case.

Add test coverage to the important features of
[`routers.web.repo.renderReadmeFile`](067b0c2664/routers/web/repo/view.go (L273);)
namely that:

- it can handle looking in docs/, .gitea/, and .github/
- it can handle choosing between multiple competing READMEs
- it prefers the localized README to the markdown README to the
plaintext README
- it can handle broken symlinks when processing all the options
- it uses the name of the symlink, not the name of the target of the
symlink

`renderReadmeFile` needs `readmeTreelink` as parameter but gets
`treeLink`.
The values of them look like as following:
`treeLink`:  `/{OwnerName}/{RepoName}/src/branch/{BranchName}`
`readmeTreelink`:
`/{OwnerName}/{RepoName}/src/branch/{BranchName}/{ReadmeFileName}`

`path.Dir` in

8540fc45b1/routers/web/repo/view.go (L316)
should convert `readmeTreelink` into
`/{OwnerName}/{RepoName}/src/branch/{BranchName}` instead of the current
`/{OwnerName}/{RepoName}/src/branch`.

Fixes #23151

# Summary

The repo information such as description, stats and topics are getting
displayed in the top-bar when viewing a file. This has been fixed to
display the repo information only while navigating the repo and not
while viewing or blaming a file from the repo

## Before fix

Screenshot from the issue


![image](https://user-images.githubusercontent.com/47709856/195278543-9afbb735-7bd3-4f42-b3ba-da514c6989d2.png)

## After the fix

- **Repo homepage**

The repo description, topics and summary will be displayed

- **When opening a file**

The repo description, topic and summary has been conditionally hidden
from the view

- **When running blame on a file**

> This was originally not part of the issue #21406. However the fix
seems relevant for the blame view as well.

- **From within a directory**

The repo description, topics and summary will not be displayed

This operation that shifts the content from title to data-content is
useless when we can directly render the expected HTML instead.

This change does prevent these tooltips from working when the user has
JS disabled in their browser, but I think we made it clear by now that
JS is required for gitea to work properly.
