Do not break URL previews if an image is unreachable. (#12950)

or is unreachable for some other reason (e.g. DNS).

Remove `HomeServer.get_datastore()` (#12031)
The presence of this method was confusing, and mostly present for backwards
compatibility. Let's get rid of it.

Implement a content type allow list for URL previews (#11936)
This implements an allow list for content types for which Synapse will attempt URL preview. If a URL resolves to a resource with a content type which isn't in the list, the download will terminate immediately.

This makes sense given that Synapse would never successfully generate a URL preview for such files in the first place, and helps prevent issues with streaming media servers, such as #8302.

Support rendering previews with data: URLs in them (#11767)
Images which are data URLs will no longer break URL

thumbnailed.

Move HTML parsing to a separate file for URL previews. (#11566)
* Splits the logic for parsing HTML from the resource handling code.
* Fix a circular import in the oEmbed code (which uses the HTML parsing code).
* Renames some of the HTML parsing methods to:
  * Make it clear which methods are "internal" to the module.
  * Clarify what the methods do.

Refactor oEmbed previews (#10814)
The major change is moving the decision of whether to use oEmbed
further up the call-stack. This reverts the _download_url method to
being a "dumb" functionwhich takes a single URL and downloads it
(as it was before #7920).

This also makes more minor refactorings:

* Renames internal variables for clarity.
* Factors out shared code between the HTML and rich oEmbed
  previews.
* Fixes tests to preview an oEmbed image.

Request JSON for oEmbed requests (and ignore XML only providers). (#10759)
This adds the format to the request arguments / URL to
ensure that JSON data is returned (which is all that
Synapse supports).

This also adds additional error checking / filtering to the
configuration file to ignore XML-only providers.

Return a 404 if no valid thumbnail is found. (#9163)
If no thumbnail of the requested type exists, return a 404 instead
of erroring. This doesn't quite match the spec (which does not define
what happens if no thumbnail can be found), but is consistent with
what Synapse already does.

Apply an IP range blacklist to push and key revocation requests. (#8821)
Replaces the `federation_ip_range_blacklist` configuration setting with an
`ip_range_blacklist` setting with wider scope. It now applies to:

* Federation
* Identity servers
* Push notifications
* Checking key validitity for third-party invite events

The old `federation_ip_range_blacklist` setting is still honored if present, but
with reduced scope (it only applies to federation and identity servers).
