This includes the `typing`, `to_device`, `account_data`, `receipts`, and `presence`
streams (really anything except the `events` stream).

Remove workaround introduced in Synapse v1.50.0rc1 for Mjolnir compatibility. Breaks compatibility with Mjolnir v1.3.1 and earlier. (#11700)

* Rewrites the demo documentation to be clearer, accurate, and moves it to our documentation tree.
* Improvements to the demo scripts:
	* `clean.sh` now runs `stop.sh` first to avoid zombie processes.
	* Uses more modern Synapse configuration (and removes some obsolete configuration).
	* Consistently use the HTTP ports for server name, etc.
	* Remove the `demo/etc` directory and place everything into the `demo/808x` directories.

* Rename scripts-dev to have suffices

* Update references to `scripts-dev`

* Changelog

* These scripts don't pass mypy

* Two scripts are basically entry_points already
* Move and rename scripts/* to synapse/_scripts/*.py
* Delete sync_room_to_group.pl
* Expose entry points in setup.py
* Update linter script and config
* Fixup scripts & docs mentioning scripts that moved

...and various code supporting it.

The /spaces endpoint was from an old version of MSC2946 and included
both a Client-Server and Server-Server API. Note that the unstable
/hierarchy endpoint (from the final version of MSC2946) is not yet
removed.

And clean-up the endpoints which should be routed to workers.

The presence of this method was confusing, and mostly present for backwards
compatibility. Let's get rid of it.

Part of #11733

Since it is reasonable to give a future or past auth provider,
which might not be in the current configuration.

The StreamHandler takes a stream parameter, not location.

Part of the Tchap Synapse mainlining.

This allows modules to implement extra logic to figure out whether a given 3PID can be added to the local homeserver. In the Tchap use case, this will allow a Synapse module to interface with the custom endpoint /internal_info.

This document isn't really relevant any more, and its existence is more confusing than helpful.

Also remove support for non-HTTP(S) web_client_location.
