Updates documentation from #9289 and removes a deprecated
endpoint which didn't work as expected.

This reverts commit 8ad4676f.

It's proving incredibly hard to build in CircleCI infra.

This API was undocumented and nonsensical.

This reduces the memory usage of previewing media files which
end up larger than the `max_spider_size` by avoiding buffering
content internally in treq.

It also checks the `Content-Length` header in additional places
instead of streaming the content to check the body length.

As the comment says, this guard was there for when the
initial user directory update has yet to happen.

This reverts commit a8878960.

This is a small bug that I noticed while working on #8956.

We have a for-loop which attempts to strip all presence changes for each user except for the final one, as we don't really care about older presence:

https://github.com/matrix-org/synapse/blob/9e19c6aab4b5a99039f2ddc7d3120dd3b26c274b/synapse/handlers/presence.py#L368-L371

`new_states_dict` stores this stripped copy of latest presence state for each user, before it is... put into a new variable `new_state`, which is just overridden by the subsequent for loop.

I believe this was instead meant to override `new_states`. Without doing so, it effectively meant:

1. The for loop had no effect.
2. We were still processing old presence state for users.

tiny typo in sso paths

Apple want to POST the OIDC auth response back to us rather than using query-params; add the necessary support to make that work.

Fixes #9347

 - Update black version to the latest
 - Run black auto formatting over the codebase
    - Run autoformatting according to [`docs/code_style.md
`](https://github.com/matrix-org/synapse/blob/80d6dc9783aa80886a133756028984dbf8920168/docs/code_style.md)
 - Update `code_style.md` docs around installing black to use the correct version

Fixes a "conflict" from 846b9d3d
and d1f13c74.

Ensure that we lock correctly to prevent multiple concurrent metadata load
requests, and generally clean up the way we construct the metadata cache.
