Fix preview of imgur and Tenor URLs. (#11669)
By scraping Open Graph information from the HTML even
when an autodiscovery endpoint is found. The results are
then combined to capture as much information as possible
from the page.

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.

Ensure each charset is attempted only once during media preview. (#11089)
There's no point in trying more than once since it is guaranteed to
continually fail.

Relax ignore-missing-imports for modules that have stubs now and update mypy (#11006)
Updating mypy past version 0.9 means that third-party stubs are no-longer distributed with typeshed. See http://mypy-lang.blogspot.com/2021/06/mypy-0900-released.html for details.
We therefore pull in stub packages in setup.py

Additionally, some modules that we were previously ignoring import failures for now have stubs. So let's use them.

The rest of this change consists of fixups to make the newer mypy + stubs pass CI.

* Handle photo/video payloads.

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.

Mitigate media repo XSSs on IE11. (#10468)
IE11 doesn't support Content-Security-Policy but it has support for
a non-standard X-Content-Security-Policy header, which only supports the
sandbox directive. This prevents script execution, so it at least offers
some protection against media repo-based attacks.

Make it possible to use dmypy (#9692)
Running `dmypy run` will do a `mypy` check while spinning up a daemon
that makes rerunning `dmypy run` a lot faster.

`dmypy` doesn't support `follow_imports = silent` and has
`local_partial_types` enabled, so this PR enables those options and
fixes the issues that were newly raised. Note that `local_partial_types`
will be enabled by default in upcoming mypy releases.
