#14910 fixed the regression introduced by #13873 where sqlite database
migrations would no longer run inside a transaction. However, it
committed the transaction before Synapse updated its bookkeeping of
which migrations have been run, which means that migrations may be run
again after they have completed successfully.
Leave the transaction open at the end of `executescript`, to restore the
old, correct behaviour. Also make the PostgreSQL behaviour consistent
with SQLite.
Fixes#14909.

* Better test for bad values in power levels events
The previous test only checked that Synapse didn't raise an exception,
but didn't check that we had correctly interpreted the value of the
dodgy power level.
It also conflated two things: bad room notification levels, and bad user
levels. There _is_ logic for converting the latter to integers, but we
should test it separately.
* Check we ignore types that don't convert to int
* Handle `None` values in `notifications.room`
* Changelog
* Also test that bad values are rejected by event auth
* Docstring
* linter scripttttttttt
MSC3952 defines push rules which searches for mentions in a list of
Matrix IDs in the event body, instead of searching the entire event
body for display name / local part.
This is implemented behind an experimental configuration flag and
does not yet implement the backwards compatibility pieces of the MSC.
* Allow `AbstractSet` in `StrCollection`
Or else frozensets are excluded. This will be useful in an upcoming
commit where I plan to change a function that accepts `List[str]` to
accept `StrCollection` instead.
* `rooms_to_exclude` -> `rooms_to_exclude_globally`
I am about to make use of this exclusion mechanism to exclude rooms for
a specific user and a specific sync. This rename helps to clarify the
distinction between the global config and the rooms to exclude for a
specific sync.
* Better function names for internal sync methods
* Track a list of excluded rooms on SyncResultBuilder
I plan to feed a list of partially stated rooms for this sync to ignore
* Exclude partial state rooms during eager sync
using the mechanism established in the previous commit
* Track un-partial-state stream in sync tokens
So that we can work out which rooms have become fully-stated during a
given sync period.
* Fix mutation of `@cached` return value
This was fouling up a complement test added alongside this PR.
Excluding a room would mean the set of forgotten rooms in the cache
would be extended. This means that room could be erroneously considered
forgotten in the future.
Introduced in #12310, Synapse 1.57.0. I don't think this had any
user-visible side effects (until now).
* SyncResultBuilder: track rooms to force as newly joined
Similar plan as before. We've omitted rooms from certain sync responses;
now we establish the mechanism to reintroduce them into future syncs.
* Read new field, to present rooms as newly joined
* Force un-partial-stated rooms to be newly-joined
for eager incremental syncs only, provided they're still fully stated
* Notify user stream listeners to wake up long polling syncs
* Changelog
* Typo fix

Currently, we will try to start a new partial state sync every time we
perform a remote join, which is undesirable if there is already one
running for a given room.
We intend to perform remote joins whenever additional local users wish
to join a partial state room, so let's ensure that we do not start more
than one concurrent partial state sync for any given room.
------------------------------------------------------------------------
There is a race condition where the homeserver leaves a room and later
rejoins while the partial state sync from the previous membership is
still running. There is no guarantee that the previous partial state
sync will process the latest join, so we restart it if needed.

Serving partial join responses is no longer experimental. They will only be served under the stable identifier if the the undocumented config flag experimental.msc3706_enabled is set to true.
Synapse continues to request a partial join only if the undocumented config flag experimental.faster_joins is set to true; this setting remains present and unaffected.
We were incorrectly checking if the *local* token had been advanced, rather than the token for the remote instance.
In practice, I don't think this has caused any bugs due to where we use `wait_for_stream_position`, as critically we don't use it on instances that also write to the given streams (and so the local token will lag behind all remote tokens).

* Read new field names from partial join response
* Changelog
When there are many synchronous requests waiting on a
`_PerHostRatelimiter`, each request will be started recursively just
after the previous request has completed. Under the right conditions,
this leads to stack exhaustion.
A common way for requests to become synchronous is when the remote
client disconnects early, because the homeserver is overloaded and slow
to respond.
Avoid stack exhaustion under these conditions by deferring subsequent
requests until the next reactor tick.
Fixes#14480.

Two parts to this:
* Bundle the whole of the replacement with any edited events. This is backwards-compatible so I haven't put it behind a flag.
* Optionally, inhibit server-side replacement of edited events. This has scope to break things, so it is currently disabled by default.
It doesn't seem valid that HTML entities should appear in
the title field of oEmbed responses, but a popular WordPress
plug-in seems to do it.
There should not be harm in unescaping these.

This change uses ICU (International Components for Unicode) to improve boundary detection in user search.
This change also adds a new dependency on libicu-dev and pkg-config for the Debian packages, which are available in all supported distros.
This should help reduce the number of devices e.g. simple bots the repeatedly login rack up.
We only delete non-e2e devices as they should be safe to delete, whereas if we delete e2e devices for a user we may accidentally break their ability to receive e2e keys for a message.
An empty cache does not mean the entity has no changed, if
it is earlier than the earliest known stream position return that
the entity *has* changed since the cache cannot accurately
answer that query.
A batch of changes intended to make it easier to trace to-device messages through the system.
The intention here is that a client can set a property org.matrix.msgid in any to-device message it sends. That ID is then included in any tracing or logging related to the message. (Suggestions as to where this field should be documented welcome. I'm not enthusiastic about speccing it - it's very much an optional extra to help with debugging.)
I've also generally improved the data we send to opentracing for these messages.
The internal methods of the StreamChangeCache were inconsistently
treating the earliest known stream position as valid. It is now treated as
invalid, meaning the cache cannot determine if an entity at the earliest
known stream position has changed or not.
