TODO for later: consider supporting Atom's `<icon>` and RSS 2.0's `<image>` https://github.com/FreshRSS/FreshRSS/issues/7774
* Implement support for HTTP 429 Too Many Requests
Will obey the corresponding HTTP `Retry-After` header at domain level.
* Implement 503 Service Unavailable
* Sanitize Retry-After
* Reduce default value when Retry-After is absent
And make configuration parameter
* Retry-After also for favicons
Closes#3789, #6503
Icon setting when no custom icon is set yet:
- `Change...` button opens a file dialog, and after selecting a file shows the chosen icon in the preview on the left. `Submit` must be clicked after selecting the icon.
- `Reset to default` changes the preview icon to the default one, and also requires `Submit` to be clicked to apply the changes.
Full list of changes:
- CSP now includes `blob:` in `img-src` for
- `indexAction()` and `feedAction()` in `subscriptionController.php`
- all of the view actions in `indexController.php`
- Introduce new attribute `customFavicon (boolean)` for feeds that indicates if the feed has a custom favicon
- `hashFavicon()` in `Feed.php` is dependent on this attribute
- `hashFavicon()` has a new parameter called `skipCache (boolean)` that allows the reset of the favicon hash for the Feed object
- `resetFaviconHash()` just calls `hashFavicon(skipCache: true)`
- `f.php` URLs now have the format of `/f.php?h=XXXXX&t=cachebuster`, where the `t` parameter is only used for serving custom favicons
- if `t` parameter is set, `f.php` returns a `Cache-Control: immutable` header
- `stripos` and `strpos` were changed to `str_contains` in various places (refactor)
- JS for handling the custom favicon configuration logic is in `extra.js` inside `init_update_feed()` which is called when feed configuration is opened from the aside or when the subscription management page with the feed is loaded
- Server-side code for uploading the icon in `subscriptionController.php` under `feedAction()`
- Errors that may occur during the setting of a custom favicon:
- Unsupported image file type (handled only server-side with `isImgMime()`)
- When the file is bigger than 1 MiB (default), handled both client-side and server-side
- Standard feed error when `updateFeed()` fails
- JS vars `javascript_vars.phtml` are no longer escaped with `htmlspecialchars()`, instead with json encoding,
- CSS for disabled buttons was added
- Max favicon file size is configurable with the `max_favicon_upload_size` option in `config.php` (not exposed via UI)
- Custom favicons are currently deleted only when they are either reset to the default icon, or the feed gets deleted. They do not get deleted when the user deletes their account without removing their feeds first.
- ` faviconPrepare()` and `faviconRebuild()` are not allowed to be called when the `customFavicon` attribute is `true`
- New i18n strings:
- `'sub.feed.icon' => 'Icon'`
- `'sub.feed.change_favicon' => 'Change…'`
- `'sub.feed.reset_favicon' => 'Reset to default'`
- `'sub.feed.favicon_changed_by_ext' => 'The icon has been set by the <b>%s</b> extension.'`
- `'feedback.sub.feed.favicon.too_large' => 'Uploaded icon is too large. The maximum file size is <em>%s</em>.'`
- `'feedback.sub.feed.favicon.unsupported_format' => 'Unsupported image file format!'`
- Extension hook `custom_favicon_hash`
- `setCustomFavicon()` method
- `resetCustomFavicon()` method
- `customFaviconExt` and `customFaviconDisallowDel` attributes
- example of usage: https://github.com/FreshRSS/Extensions/pull/337
- Extension hook `custom_favicon_btn_url`
- Allows extensions to implement a button for setting a custom favicon for individual feeds by providing an URL. The URL will be sent a POST request with the `extAction` field set to either `query_icon_info` or `update_icon`, along with an `id` field which describes the feed's ID.

URL parameters:
* `&sort=id` (current behaviour, sorting according to newest received articles)
* `&sort=date` (publication date, which is not indicative of how new an article is)
* `&sort=title`
* `&sort=link`
* `&sort=rand` (random order - which disables infinite scrolling, at least for now)
combined with `&order=ASC` or `&order=DESC`
## Implementation notes
The sorting criteria by *received date* (id), which is the default, and which was the only one before this PR, is the one that has the best sorting characteristics:
* *uniqueness*: no entries have the exact same received date
* *monotonicity*: new entries always have a higher received date
* *performance*: this field is efficiently indexed in database for fast usage, including for paging (indexing could also be done to other fields, but with lower effective performance)
In contrary, sorting criteria such as by *publication date*, by *title*, or by *link* are neither unique nor monotonic. In particular, multiple articles may share the same *publication date*, and we may receive articles with a *publication date* far in the future, and then later some new articles with a *publication date* far in the past.
To understand why sorting by *publication date* is problematic, it helps to think about sorting by *title* or by *link*, as sorting by *title* and by *publication date* share more or less the same characteristics.
### Problem 1: new articles
New articles may be received in the background after what is shown on screen, and before the next user action such as *mark all as read*. Due to the lack of *monotonicity* when sorting by e.g. *publication date* or *title*, users risk marking as read a batch of articles containing some fresh articles without seeing them.
Mitigation: A parameter `idMax` tracks the maximum ID related to a batch of actions such as *mark all as read* to exclude articles received after those that are displayed.
### Problem 2: paging / pagination
When navigating articles, only a few articles are displayed, and a new "page" of articles needs to be received from the database when scrolling down or when clicking the button to show more articles. When sorting by e.g. *publication date* or *title*, it is not trivial to show the next page without re-showing some of the same articles, and without skipping any. Indeed, views are often with additional criteria such as showing only unread articles, and users may mark some articles as read while viewing them, hereby removing some articles from the previous pages. And like for *Problem 1*, new articles may have been received in the background. Consequently, it is not possible to use `OFFSET` to implement pagination (so the patches suggested by a few users were wrong due to that, in particular).
Mitigation: `idMax` is also used (just like for *Problem 1*) and a *Keyset Pagination* approach is used, combining an unstable sorting criterion such as *publication date* or *title*, together with *id* to ensure stable sorting. (So, 2 sorting criteria + 1 filter criteria)
See e.g. https://www.alwaysdeveloping.net/dailydrop/2022/07/01-keyset-pagination/
### Problem 3: performance
Sorting by anything else than *received date* (id) is doomed to be slow(er) due to the combination of 3 criteria (see *Problem 2*). An `OFFSET` approach (which is not possible anyway as explained) would be even slower. Furthermore, we have no SQL index at the moment, but they would not necessarily help much due to the multiple sorting criteria needed and involving some `OR` logic which is difficult to optimise for databases.
The nicest syntax would be using tuples and corresponding indexes, but that is poorly supported by MySQL https://bugs.mysql.com/bug.php?id=104128
Mitigation: a compatibility SQL syntax is used to implement *Keyset Pagination*
### Problem 4: user confusion
Several users have shown that they do not fully understand the difference between *received date* and *publication date*, and particularly not the pitfalls of *publication date*.
Mitigation: the menus to mark-as-read *before 1 day* and *before 1 week* are disabled when sorting by anything else than *received date*. Likewise, the separation headers *Today* and *Yesterday* and *Before yesterday* are only shown when sorting by *received date*.
Again here, to better understand why, it helps to think about sorting by *title* or by *link*, as sorting by *title* and by *publication date* share more or less the same characteristics.
* [ ] We should write a Q&A and/or documentation about the problems associated to *sorting by publication date*: risks of not noticing new publication, of inadvertently marking them as read, of having some articles with a date in the future hanging at the top of the views (vice versa when sorting in ascending order), performance, etc.
### Problem 5: APIs
Sorting by anything else than *received date* breaks the guarantees needed for a successful synchronisation via API.
Mitigation: sorting by *received date* is ensured for all API calls.

New set of unicity criteria options.
New tolerance heuristic:
> `$invalidGuidsTolerance` (default 0.05) The maximum ratio (rounded) of invalid GUIDs to tolerate before degrading the unicity criteria.
> Example for 0.05 (5% rounded): tolerate 0 invalid GUIDs for up to 9 articles, 1 for 10, 2 for 30, 3 for 50, 4 for 70, 5 for 90, 6 for 110, etc.
> The default value of 5% rounded was chosen to allow 1 invalid GUID for feeds of 10 articles, which is a frequently observed amount of articles.
* New feed mode: HTML + XPath + JSON dot notation (JSON in HTML)
Same as `JSON+DotNotation` but first extracting the JSON string from an HTML document thanks to an XPath expression.

When the option *mark as read if an identical title already exists in the top n newest articles*, that should not apply to updated articles, as they risk being marked as read due to themselves having the same title.
Identifying the different sub-cases would require a more complicated logic, so disable for now.
Regression due to https://github.com/FreshRSS/FreshRSS/pull/6334
* New feature: shareable user query
Share the output of a user query by RSS / HTML / OPML with other people through unique URLs.
Replaces the global admin token, which was the only option (but unsafe) to share RSS outputs with other people.
Also add a new HTML output for people without an RSS reader.
