Ensure that the list of servers in a partial state room always contains
the server we joined off.
Also refactor `get_partial_state_servers_at_join` to return `None` when
the given room is no longer partial stated, to explicitly indicate when
the room has partial state. Otherwise it's not clear whether an empty
list means that the room has full state, or the room is partial stated,
but the server we joined off told us that there are no servers in the
room.

Since pyo3-log is initialized very early in the Python start-up
it caches the state of the loggers before they're fully initialized
(and thus are essentially disabled). Whenever we reload the
logging configuration we now also tell pyo3-log to discard
any cached logging configuration it has; it will refetch the
current logging configuration from Python at the next point
it logs.
This fixes Rust log lines not appearing in the homeserver logs.
If a sync request does not need to calculate per-room entries &
is not generating presence & is not generating device list data
(e.g. during initial sync) avoid the expensive calculation of room
specific data.
This is a micro-optimisation for clients syncing simply to receive
to-device information.
This expands the previous optimisation from being only for initial
sync to being for all sync requests.
It also inverts some of the logic to be inclusive instead of exclusive.
The `parse_enum` helper pulls an enum value from the query string
(by delegating down to the parse_string helper with values generated
from the enum).
This is used to pull out "f" and "b" in most places and then we thread
the resulting Direction enum throughout more code.
The previous assumption was that the stream_id column was unique
(for a room ID, receipt type, user ID tuple), but this turned out to be
incorrect.
Now find the max stream ID, then map this back to a database-specific
row identifier and delete other rows which match the (room ID, receipt type,
user ID) tuple, but *not* the row ID.
`run_in_background` calls re-use the current logging context. When they
are not awaited, they can complete after the current logging context has
been marked as finished, which leads to log spam. Use
`run_as_background_process` instead.
Fixes one of the instances of #13090.

#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
* Test boolean values in PL content
* Reject boolean power levels
* Changelog
* Perfer `type(x) is int` to `isinstance(x, int)`
This covered all additional instances I could see where `x` was
user-controlled.
The remaining cases are
```
$ rg -s 'isinstance.*[^_]int'

576: if isinstance(obj, int):
synapse/util/caches/stream_change_cache.py

which cover metrics, logic related to `jsonschema`, and replication and
data streams. AFAICS these are all internal to Synapse

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.
The `/relations` endpoint was not properly handle "live tokens"
(i.e sync tokens), to do this properly we abstract the code that
`/messages` has and re-use it.
Destination was being used incorrectly (a single destination instead
of a list of destinations was being passed).
This also updates some of the types in the area to not use Collection[str],
which is a footgun.
* Bump the client-side timeout for /state
to allow faster joins resyncs the chance to complete for large rooms.
We have seen this fair poorly (~90s for Matrix HQ's /state) in testing,
causing the resync to advance to another HS who hasn't seen our join yet.

* Milliseconds!!!!
#13873 introduced a regression which causes sqlite database migrations
to no longer run inside a transaction. Wrap them in a transaction again,
to avoid database corruption when migrations are interrupted.
Fixes#14909.

* Request partial joins by default
This is a little sloppy, but we are trying to gain confidence in faster
joins in the upcoming RC.
Admins can still opt out by adding the following to their Synapse
config:
```yaml
experimental:
faster_joins: false
```
We may revert this change before the release proper, depending on how
testing in the wild goes.
* Changelog
* Try to fix the backfill test failures
* Upgrade notes
* Postgres compat?
* 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
