Remove `[repository.editor] PREVIEWABLE_FILE_MODES` setting that seemed
like it was intended to support this but did not work. Instead, whenever
viewing a file shows a preview, also have a Preview tab in the file
editor.
Add new `/markup` web and API endpoints with `comment`, `gfm`,
`markdown` and new `file` mode that uses a file path to determine the
renderer.
Remove `/markdown` web endpoint but keep the API for backwards and
GitHub compatibility.
## ⚠️ BREAKING ⚠️
The `[repository.editor] PREVIEWABLE_FILE_MODES` setting was removed.
This setting served no practical purpose and was not working correctly.
Instead a preview tab is always shown in the file editor when supported.

This branch continues the work of #23092 and attempts to rid the
codebase of any `nil` contexts when using a `RenderContext`.
Anything that renders markdown or does post processing may call
`markup.sha1CurrentPatternProcessor()`, and this runs
`git.OpenRepository()`, which needs a context. It will panic if the
context is `nil`. This branch attempts to _always_ include a context
when creating a `RenderContext` to prevent future crashes.

As you can imagine, for the Blender development process it is rather
nice to be able to include videos in issues, pull requests, etc.
This PR allows the `<video>` HTML tag to be used in MarkDown, with the
`src`, `autoplay`, and `controls` attributes.
## Help Needed
To have this fully functional, personally I feel the following things
are still missing, and would appreciate some help from the Gitea team.
### Styling
Some CSS is needed, but I couldn't figure out which of the LESS files
would work. I tried `web_src/less/markup/content.less` and
`web_src/less/_base.less`, but after running `make` the changes weren't
seen in the frontend.
This I would consider a minimal set of CSS rules to be applied:
```css
video {
max-width: 100%;
max-height: 100vh;
}
```
### Default Attributes
It would be fantastic if Gitea could add some default attributes to the
`<video>` tag. Basically `controls` should always be there, as there is
no point in disallowing scrolling through videos, looping them, etc.
### Integration with the attachments system
Another thing that could be added, but probably should be done in a
separate PR, is the integration with the attachments system. Dragging in
a video should attach it, then generate the appropriate MarkDown/HTML.
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?

The behaviour of `PreventSurroundingPre` has changed in
https://github.com/alecthomas/chroma/pull/618 so that apparently it now
causes line wrapper tags to be no longer emitted, but we need some form
of indication to split the HTML into lines, so I did what
https://github.com/yuin/goldmark-highlighting/pull/33 did and added the
`nopWrapper`.
Maybe there are more elegant solutions but for some reason, just
splitting the HTML string on `\n` did not work.

Remove two unmaintained vendor packages `i18n` and `paginater`. Changes:
* Rewrite `i18n` package with a more clear fallback mechanism. Fix an unstable `Tr` behavior, add more tests.
* Refactor the legacy `Paginater` to `Paginator`, test cases are kept unchanged.
Trivial enhancement (no breaking for end users):
* Use the first locale in LANGS setting option as the default, add a log to prevent from surprising users.
The main purpose is to refactor the legacy `unknwon/com` package.
1. Remove most imports of `unknwon/com`, only `util/legacy.go` imports the legacy `unknwon/com`
2. Use golangci's depguard to process denied packages
3. Fix some incorrect values in golangci.yml, eg, the version should be quoted string `"1.18"`
4. Use correctly escaped content for `go-import` and `go-source` meta tags
5. Refactor `com.Expand` to our stable (and the same fast) `vars.Expand`, our `vars.Expand` can still return partially rendered content even if the template is not good (eg: key mistach).

* Prevent double sanitize.
* Use SanitizeReaderToWriter.
At the moment `actualRender` uses `SanitizeReader` to sanitize the output. But `SanitizeReader` gets called in `markup.render` too so the output gets sanitized twice.
I moved the `SanitizeReader` call into `RenderRaw` because this method does not use `markup.render`. I would like to remove the `RenderRaw`/`RenderRawString` methods too because they are only called from tests, the fuzzer and the `/markup/raw` api endpoint. This endpoint is not in use so I think we could remove them. If we really in the future need a method to render markdown without PostProcessing we could achieve this with a more flexible `renderer.NeedPostProcess` method.

When matching emoji, use a regex built from the data we have instead of something generic using unicode ranges. A generic regex can't tell the difference between two separate emoji next to each other or one emoji that is built out of two separate emoji next to each other.
This means that emoji that are next to each other without space in between will be now accurately spanned individually with proper title etc...
GH has different HardBreaks behaviour for markdown comments and documents.
Comments have hard breaks and documents have soft breaks - therefore Gitea's rendering will always be different from GH's if we only provide one setting.
Here we split the setting in to two - one for documents and one for comments and other things.

* Support unicode emojis and remove emojify.js
This PR replaces all use of emojify.js and adds unicode emoji support to various areas of gitea.
This works in a few ways:
First it adds emoji parsing support into gitea itself. This allows us to
* Render emojis from valid alias (😄)
* Detect unicode emojis and let us put them in their own class with proper aria-labels and styling
* Easily allow for custom "emoji"
* Support all emoji rendering and features without javascript
* Uses plain unicode and lets the system render in appropriate emoji font
* Doesn't leave us relying on external sources for updates/fixes/features
That same list of emoji is also used to create a json file which replaces the part of emojify.js that populates the emoji search tribute. This file is about 35KB with GZIP turned on and I've set it to load after the page renders to not hinder page load time (and this removes loading emojify.js also)
For custom "emoji" it uses a pretty simple scheme of just looking for /emojis/img/name.png where name is something a user has put in the "allowed reactions" setting we already have. The gitea reaction that was previously hard coded into a forked copy of emojify.js is included and works as a custom reaction under this method.
The emoji data sourced here is from https://github.com/github/gemoji which is the gem library Github uses for their emoji rendering (and a data source for other sites). So we should be able to easily render any emoji and :alias: that Github can, removing any errors from migrated content. They also update it as well, so we can sync when there are new unicode emoji lists released.
I've included a slimmed down and slightly modified forked copy of https://github.com/knq/emoji to make up our own emoji module. The code is pretty straight forward and again allows us to have a lot of flexibility in what happens.
I had seen a few comments about performance in some of the other threads if we render this ourselves, but there doesn't seem to be any issue here. In a test it can parse, convert, and render 1,000 emojis inside of a large markdown table in about 100ms on my laptop (which is many more emojis than will ever be in any normal issue). This also prevents any flickering and other weirdness from using javascript to render some things while using go for others.
Not included here are image fall back URLS. I don't really think they are necessary for anything new being written in 2020. However, managing the emoji ourselves would allow us to add these as a feature later on if it seems necessary.

Annoyingly goldmarks SetAttributeString requires that
the value of the attribute is still a []byte but does
not make it clear in the documentation.

* Fix task-list checkbox styling
The pandoc renderer will append the class "task-list" to the ul element
wrapping a li with one or more check-boxes. This allows us to select for
them, removing their list-style-type property. However, goldmark and the
gfm spec doesn't specify the "task-list" class name, so we can't use
that to fix the issue there.

* Don't manually replace whitespace during render
For historical reasons Gitea manually alters the urlPrefix and replaces
a whitespace with a +. This Works for URLs, but we're also passing
urlPrefix to git calls and adding the + is breaking the tree path.
Goldmark will automatically convert a white space to the proper %20, so
we should leave the string as is which lets us pass it to git unmodified
and then let Goldmark fix it.
Also fixed separate bug in URLJoin I noticed while testing where it will
silently discard sections of a path that have # in them (possibly
others). We should just escape it first.

* Move to goldmark
Markdown rendering moved from blackfriday to the goldmark.
Multiple subtle changes required to the goldmark extensions to keep
current rendering and defaults.
Can go further with goldmark linkify and have this work within markdown
rendering making the link processor unnecessary.
Need to think about how to go about allowing extensions - at present it
seems that these would be hard to do without recompilation.
* linter fixes
