Add logging to tasks managed by the task scheduler, showing CPU and database usage. (#17219)
The log format is the same as the request log format, except:

- fields that are specific to HTTP requests have been removed
- the task's params are included at the end of the log line.

These log lines are emitted:
- when the task function finishes — both completion and failure (and I
suppose it is possible for a task to become schedulable again?)
- every 5 minutes whilst it is running

Closes #17217.

Add optimisation to StreamChangeCache (#17130)
When there have been lots of changes compared with the number of
entities, we can do a fast(er) path.

Locally I ran some benchmarking, and the comparison seems to give the
best determination of which method we use.

Ensure that pending to-device events are sent over federation at startup (#16925)
Fixes https://github.com/element-hq/synapse/issues/16680, as well as a
related bug, where servers which we had *never* successfully sent an
event to would not be retried.

In order to fix the case of pending to-device messages, we hook into the
existing `wake_destinations_needing_catchup` process, by extending it to
look for destinations that have pending to-device messages. The
federation transmission loop then attempts to send the pending to-device
messages as normal.

Don't invalidate the entire event cache when we purge history (#16905)
We do this by adding support to the LRU cache for "extra indices" based
on the cached value. This allows us to efficiently map from room ID to
the cached events and only invalidate those.

Speed up deleting device messages (#16643)
Keeping track of a lower bound of stream ID where we've deleted everything below makes the queries much faster. Otherwise, every time we scan for rows to delete we'd re-scan across all the rows that have previously deleted (until the next table VACUUM).

Collect information for PushRuleEvaluator in parallel. (#16590)
Fetch information needed for push rule evaluation in parallel.
Ideally this would use query pipelining, but this is not
available in psycopg2.

Due to the database thread pool this may result in little
to no parallelization.

Fix bug with new task scheduler using lots of CPU. (#16278)
Using the new `TaskScheduler` meant that we'ed create lots of new

resulting in requests for metrics taking an increasing amount of CPU.

Allow config of the backoff algorithm for the federation client. (#15754)
Adds three new configuration variables:

* destination_min_retry_interval is identical to before (10mn).
* destination_retry_multiplier is now 2 instead of 5, the maximum value will
  be reached slower.
* destination_max_retry_interval is one day instead of (essentially) infinity.

Capping this will cause destinations to continue to be retried sometimes instead
of being lost forever. The previous value was 2 ^ 62 milliseconds.

Fix HomeServers leaking during trial test runs (#15630)
This change fixes two memory leaks during `trial` test runs.

Garbage collection is disabled during each test case and a gen-0 GC is
run at the end of each test. However, when the gen-0 GC is run, the
`TestCase` object usually still holds references to the `HomeServer`
used during the test. As a result, the `HomeServer` gets promoted to
gen-1 and then never garbage collected.

Fix this by periodically running full GCs.

Additionally, fix `HomeServer`s leaking after tests that touch inbound
federation due to `FederationRateLimiter`s adding themselves to a global
set, by turning the set into a `WeakSet`.

Resolves #15622.
