FIX: Only block domains at the final destination (#15689) (#15783)
In an earlier PR, we decided that we only want to block a domain if 
the blocked domain in the SiteSetting is the final destination (/t/59305). That 
PR used `FinalDestination#get`. `resolve` however is used several places
 but blocks domains along the redirect chain when certain options are provided.

This commit changes the default options for `resolve` to not do that. Existing
users of `FinalDestination#resolve` are
- `Oneboxer#external_onebox`
- our onebox helper `fetch_html_doc`, which is used in amazon, standard embed 
and youtube
  - these folks already go through `Oneboxer#external_onebox` which already
  blocks correctly

FIX: origins_to_regexes should always return an array (#15589)
If the SiteSetting `allowed_onebox_iframes` contains a value of `*`, it will use the values of `all_iframe_origins` during the Oneboxing process. If `all_iframe_origins` itself contains a value of `*`, `origins_to_regexes` will try to return a "catch-all" regex.

Other code assumes `origins_to_regexes`will return an array, so this change ensures the `*` case will return an array containing only the catch-all regex.

FIX: Broken GitHub folder onebox logic (#15612)
1. `html_doc.css('.Box.md')` always returns a truthy value (e.g. `[]`) so the second branch of the if-elsif never ran
2. `node&.css('text()')` was invalid code that would raise an error
3. Matching on h3 elements is no longer correct with the current html structure returned by GitHub

- Display an image placeholder in the composer preview
- A cooked post should use an iframe to display the Instagram 'embed' content

d27d7c8cca FIX: Unescapes hash section with present to account for url-encoded chars
Sections with unreserverd characters will appear url-encoded and need to
be unescaped before using it.

Wikipedia generates 2 different spans in this case in the same page, one
with an id resulting of replacing the % symbols with . and the other with
the decoded version of the string. For example, for /wiki/foo#A%C3%A1A it
will generate:

<span id="A.C3.A1A"></span>
<span id="AáA">AáA</span>

Unescaping the `m_url_hash_name` should work in all cases to target the
proper section span.

FEATURE: Onebox can match engines based on the content_type (#13876)
* FEATURE: Onebox can match engines based on the content_type

`FinalDestination` now returns the `content_type` of a resolved URL.

`Oneboxer` passes this value to `Onebox` itself. Onebox engines can now specify a `matches_content_type` regex of content_types that the engine can handle, regardless of the URL.

`ImageOnebox` will match URLs with a content type of `image/png`, `jpg`, `gif`, `bmp`, `tif`, etc.

This will allow images that exist at a URL without a file type extension to be correctly rendered, assuming a valid `content_type` is returned.

FIX: Don’t use user_generated images as avatar images in Oneboxed Twitter content (#13712)
By default, Twitter will return the URL for the avatar image of the tweet poster as the `og:image` value.

However, if the `user_generated` attribute is true, we should not use this as the avatar URL as this will be an URL of an image in the tweet itself (e.g., an image belonging to a tweeted news story).

FIX: IMDb links were being oneboxed as posters (#13310)
IMDb movie links were being rendered as posters. This was because
IMDb was sending `og:type` as `image` randomly in some cases. To
fix this we'll now default all IMDb links as article type. This will
ensure that the IMDb onebox link includes all the information instead
of showing just a poster without any context.

Onebox improved error handling and support for Instagram Access Tokens (#11253)
* FEATURE: display error if Oneboxing fails due to HTTP error

- display warning if onebox URL is unresolvable
- display warning if attributes are missing

* FEATURE: Use new Instagram oEmbed endpoint if access token is configured

Instagram requires an Access Token to access their oEmbed endpoint. The requirements (from https://developers.facebook.com/docs/instagram/oembed/) are as follows:

- a Facebook Developer account, which you can create at developers.facebook.com
- a registered Facebook app
- the oEmbed Product added to the app
- an Access Token
- The Facebook app must be in Live Mode

The generated Access Token, once added to SiteSetting.facebook_app_access_token, will be passed to onebox. Onebox can then use this token to access the oEmbed endpoint to generate a onebox for Instagram.

* DEV: update user agent string

* DEV: don’t do HEAD requests against news.yahoo.com

* DEV: Bump onebox version from 2.1.5 to 2.1.6

* DEV: Avoid re-reading templates

* DEV: Tweaks to onebox mustache templates

* DEV: simplified error message for missing onebox data

* Apply suggestions from code review

DEV: enforces ember-template-lint: no-triple-curlies (#9150)
This pr replaces `{{{ }}}` usage by a {{html-safe}} helper. While it doesn't solve the underlying issue, it gives us a path forward without risking breaking too much existing behavior.

Also introduces an htmlSafe computed macro:

```
import { htmlSafe } from "discourse/lib/computed";

htmlDescription: htmlSafe("description")
```

Overtime {{html-safe}} usage should be removed and moved to components properties or specialized components/helpers.
