Adds validation to the Client-Server API to ensure that
the potential thread head does not relate to another event
already. This results in not allowing a thread to "fork" into
other threads.
If the target event is unknown for some reason (maybe it isn't
visible to your homeserver), but is the target of other events
it is assumed that the thread can be created from it. Otherwise,
it is rejected as an unknown event.

`synapse.config.__main__` has the possibility to read a config item. This can be used to conveniently also validate the config is valid before trying to start Synapse.
The "read" command broke in https://github.com/matrix-org/synapse/pull/10916 as it now requires passing in "server.server_name" for example.
Also made the read command optional so one can just call this with just the confirm file reference and get a "Config parses OK" if things are ok.

* We only need to fetch users in private rooms
* Filter out `user_id` at the top
* Discard excluded users in the top loop
We weren't doing this in the "First, if they're our user" branch so this
is a bugfix.
* The caller must check that `user_id` is included
This is in the docstring. There are two call sites:
- one in `_handle_room_publicity_change`, which explicitly checks before calling;
- and another in `_handle_room_membership_event`, which returns early if
the user is excluded.
So this change is safe.
* Test joining a private room with an excluded user
* Tweak an existing test
* Changelog
* test docstring
* lint
This fixes a bug where we would accept an event whose `auth_events` include
rejected events, if the rejected event was shadowed by another `auth_event`
with same `(type, state_key)`.
The approach is to pass a list of auth events into
`check_auth_rules_for_event` instead of a dict, which of course means updating
the call sites.
This is an extension of #10956.
Found while working on the Gitter backfill script and noticed
it only happened after we sent 7 batches, https://gitlab.com/gitterHQ/webapp/-/merge_requests/2229#note_665906390
When there are more than 5 backward extremities for a given depth,
backfill will throw an error because we sliced the extremity list
to 5 but then try to iterate over the full list. This causes
us to look for state that we never fetched and we get a `KeyError`.
Before when calling `/messages` when there are more than 5 backward extremities:
```

The following scenarios would halt the user directory updater:
- user joins room
- user leaves room
- user present in room which switches from private to public, or vice versa.
for two classes of users:
- appservice senders
- users missing from the user table.
If this happened, the user directory would be stuck, unable to make forward progress.
Exclude both cases from the user directory, so that we ignore them.

This reverts #11019 and structures the code a bit more like it was before #10985.
The global cache state must be reset before running the tests since other test
cases might have configured caching (and thus touched the global state).
Make `get_last_client_by_ip` return the same dictionary structure
regardless of whether the data has been persisted to the database.
This change will allow slightly cleaner type hints to be applied later
on.
This splits apart `handle_new_user` into a function which adds an entry to the `user_directory` and a function which updates the room sharing tables. I plan to continue doing more of this kind of refactoring to clarify the implementation.
This removes the magic allowing accessing configurable
variables directly from the config object. It is now required
that a specific configuration class is used (e.g. `config.foo`
must be replaced with `config.server.foo`).
Fix a long-standing bug where a batch of user directory changes would be
silently dropped if the server left a room early in the batch.

There are two steps to rebuilding the user directory:
1. a scan over rooms, followed by
2. a scan over local users.
The former reads avatars and display names from the `room_memberships`
table and therefore contains potentially private avatars and
display names. The latter reads from the the `profiles` table which only
contains public data; moreover it will overwrite any private profiles
that the rooms scan may have written to the user directory. This means
that the rebuild could leak private user while the rebuild was in
progress, only to later cover up the leaks once the rebuild had completed.
This change skips over local users when writing user_directory rows
when scanning rooms. Doing so means that it'll take longer for a rebuild
to make local users searchable, which is unfortunate. I think a future
PR can improve this by swapping the order of the two steps above. (And
indeed there's more to do here, e.g. copying from `profiles` without
going via Python.)
Small tidy-ups while I'm here:
* Remove duplicated code from test_initial. This was meant to be pulled into `purge_and_rebuild_user_dir`.
* Move `is_public` before updating sharing tables. No functional change; it's still before the first read of `is_public`.
* Don't bother creating a set from dict keys. Slightly nicer and makes the code simpler.

* Introduce `should_include_local_users_in_dir`
We exclude three kinds of local users from the user_directory tables. At
present we don't consistently exclude all three in the same places. This
commit introduces a new function to gather those exclusion conditions
together. Because we have to handle local and remote users in different
ways, I've made that function only consider the case of remote users.
It's the caller's responsibility to make the local versus remote
distinction clear and correct.
A test fixup is required. The test now hits a path which makes db
queries against the users table. The expected rows were missing, because
we were using a dummy user that hadn't actually been registered.
We also add new test cases to covert the exclusion logic.
----
By my reading this makes these changes:
* When an app service user registers or changes their profile, they will
_not_ be added to the user directory. (Previously only support and
deactivated users were excluded). This is consistent with the logic that
rebuilds the user directory. See also [the discussion
here](https://github.com/matrix-org/synapse/pull/10914#discussion_r716859548).
* When rebuilding the directory, exclude support and disabled users from
room sharing tables. Previously only appservice users were excluded.
* Exclude all three categories of local users when rebuilding the
directory. Previously `_populate_user_directory_process_users` didn't do
any exclusion.

This fixes a "Event not signed by authorising server" error when
transition room member from join -> join, e.g. when updating a
display name or avatar URL for restricted rooms.
This follows a correction made in twisted/twisted#1664 and should fix our Twisted Trial CI job.
Until that change is in a twisted release, we'll have to ignore the type
of the `host` argument. I've raised #10899 to remind us to review the
issue in a few months' time.
* Pull out GetUserDirectoryTables helper
* Don't rebuild the dir in tests that don't need it
In #10796 I changed registering a user to add directory entries under.
This means we don't have to force a directory regbuild in to tests of
the user directory search.

Broadly, the existing `event_auth.check` function has two parts:
* a validation section: checks that the event isn't too big, that it has the rught signatures, etc.
This bit is independent of the rest of the state in the room, and so need only be done once
for each event.
* an auth section: ensures that the event is allowed, given the rest of the state in the room.
This gets done multiple times, against various sets of room state, because it forms part of
the state res algorithm.
Currently, this is implemented with `do_sig_check` and `do_size_check` parameters, but I think
that makes everything hard to follow. Instead, we split the function in two and call each part
separately where it is needed.
* Inline `_check_event_auth` for outliers
When we are persisting an outlier, most of `_check_event_auth` is redundant:
* `_update_auth_events_and_context_for_auth` does nothing, because the
`input_auth_events` are (now) exactly the event's auth_events,
which means that `missing_auth` is empty.
* we don't care about soft-fail, kicking guest users or `send_on_behalf_of`
for outliers
... so the only thing that matters is the auth itself, so let's just do that.
* `_auth_and_persist_fetched_events_inner`: de-async `prep`
`prep` no longer calls any `async` methods, so let's make it synchronous.
* Simplify `_check_event_auth`
We no longer need to support outliers here, which makes things rather simpler.
* changelog
* lint
