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.

Remove various bits of compatibility code for Python <3.6 (#9879)

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`

Don't bother responding to client requests that have already disconnected (#8465)
This PR ports the quick fix from https://github.com/matrix-org/synapse/pull/2796 to further methods which handle media, URL preview and `/key/v2/server` requests. This prevents a harmless `ERROR` that comes up in the logs when we were unable to respond to a client request when the client had already disconnected. In this case we simply bail out if the client has already done so.

This is the 'simple fix' as suggested by https://github.com/matrix-org/synapse/issues/5304#issuecomment-574740003.

Fix bug in remote thumbnail search (#8438)
#7124 changed the behaviour of remote thumbnails so that the thumbnailing method was included in the filename of the thumbnail. To support existing files, it included a fallback so that we would check the old filename if the new filename didn't exist.

Unfortunately, it didn't apply this logic to storage providers, so any thumbnails stored on such a storage provider was broken.

Include method in thumbnail media name (#7124)
This fixes an issue where different methods (crop/scale) overwrite each other.

This first tries the new path. If that fails and we are looking for a
remote thumbnail, it tries the old path. If that still isn't found, it
continues as normal.

This should probably be removed in the future, after some of the newer
thumbnails were generated with the new path on most deployments. Then
the overhead should be minimal if the other thumbnails need to be
regenerated.

The `http_proxy` and `HTTPS_PROXY` env vars can be set to a `host[:port]` value which should point to a proxy.

The proxy will then be used for
 * push
 * url previews
 * phone-home stats
 * recaptcha validation
 * CAS auth validation

It will *not* be used for:

becuase the response body was too large.
