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

Part of #11733

Fetch images when previewing Twitter URLs. (#11985)
By including "bot" in the User-Agent, which some sites use
to decide whether to include additional Open Graph information.

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.

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.

Attempt different character encodings when previewing a URL. (#11077)
This follows similar logic to BeautifulSoup where we attempt different
character encodings until we find one which works.

Autodiscover oEmbed endpoint from returned HTML (#10822)

Avoid storing URL cache files in storage providers (#10911)

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.

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.

Add support for no_proxy and case insensitive env variables (#9372)
### Changes proposed in this PR

- Add support for the `no_proxy` and `NO_PROXY` environment variables
  - Internally rely on urllib's [`proxy_bypass_environment`](bdb941be42/Lib/urllib/request.py (L2519))
- Extract env variables using urllib's `getproxies`/[`getproxies_environment`](bdb941be42/Lib/urllib/request.py (L2488)) which supports lowercase + uppercase, preferring lowercase, except for `HTTP_PROXY` in a CGI environment

This does contain behaviour changes for consumers so making sure these are called out:
- `no_proxy`/`NO_PROXY` is now respected
- lowercase `https_proxy` is now allowed and taken over `HTTPS_PROXY`

Related to #9306 which also uses `ProxyAgent`

Try to recover from unknown encodings when previewing media. (#9164)
Treat unknown encodings (according to lxml) as UTF-8
when generating a preview for HTML documents. This
isn't fully accurate, but will hopefully give a reasonable
