Refactor media modules. (#15146)
* Removes the `v1` directory from `test.rest.media.v1`.
* Moves the non-REST code from `synapse.rest.media.v1` to `synapse.media`.
* Flatten the `v1` directory from `synapse.rest.media`,  but leave compatiblity
  with 3rd party media repositories and spam checkers.

Do not fail completely if oEmbed autodiscovery fails. (#15092)
Previously if an autodiscovered oEmbed request failed (e.g. the
oEmbed endpoint is down or does not exist) then the entire URL
preview would fail. Instead we now return everything we can, even
if this additional request fails.

Do not break URL previews if an image is unreachable. (#12950)
Avoid breaking a URL preview completely if the chosen image 404s
or is unreachable for some other reason (e.g. DNS).

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
previews and will properly be "downloaded" and
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.

Autodiscover oEmbed endpoint from returned HTML (#10822)
Searches the returned HTML for an oEmbed endpoint using the
autodiscovery mechanism (`<link rel=...>`), and will request it
to generate the preview.

Avoid storing URL cache files in storage providers (#10911)
URL cache files are short-lived and it does not make sense to offload
them (eg. to the cloud) or back them up.

Include more information in oEmbed previews. (#10819)
* Improved titles (fall back to the author name if there's not title) and include the site name.
* Handle photo/video payloads.
* Include the original URL in the Open Graph response.
* Fix the expiration time (by properly converting from seconds to milliseconds).

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.

Allow configuration of the oEmbed URLs. (#10714)
This adds configuration options (under an `oembed` section) to
configure which URLs are matched to use oEmbed for URL
previews.

Remove redundant "coding: utf-8" lines (#9786)
Part of #9744

Removes all redundant `# -*- coding: utf-8 -*-` lines from files, as python 3 automatically reads source code as utf-8 now.

Richard van der Hoff 129ae841e5 Make make_request actually render the request
remove the stubbing out of `request.process`, so that `requestReceived` also renders the request via the appropriate resource.

Replace render() with a stub for now.

URL preview blacklisting fixes (#5155)
Prevents a SynapseError being raised inside of a IResolutionReceiver and instead opts to just return 0 results. This thus means that we have to lump a failed lookup and a blacklisted lookup together with the same error message, but the substitute should be generic enough to cover both cases.
