Check the user_id passed to a couple of APIs for validity, to avoid
"IndexError: list index out of range" exception which looks scary and results
in a 500 rather than a more useful error.
Fixes#1432, among other things
Avoid throwing a (harmless) exception when we try to write an error response to
an http request where the client has disconnected.
This comes up as a CRITICAL error in the logs which tends to mislead people
into thinking there's an actual problem
For each request, track the amount of time spent waiting for a db
connection. This entails adding it to the LoggingContext and we may as well add
metrics for it while we are passing.
It turns out that the only thing we use the __dict__ of LoggingContext for is
`request`, and given we create lots of LoggingContexts and then copy them every
time we do a db transaction or log line, using the __dict__ seems a bit
redundant. Let's try to optimise things by making the request attribute
explicit.
ObserveableDeferred expects its callbacks to be called without any
logcontexts, whereas it turns out we were calling them with the logcontext of
the request which initiated the persistence loop.
It seems wrong that we are attributing work done in the persistence loop to the
request that happened to initiate it, so let's solve this by dropping the
logcontext for it.
(I'm not sure this actually causes any real problems other than messages in the
debug log, but let's clean it up anyway)
In order to circumvent the number of duplicate foo:count metrics increasing
without bounds, it's time for a rearrangement.
The following are all deprecated, and replaced with synapse_util_metrics_block_count:

synapse_util_metrics_block_ru_stime:count
synapse_util_metrics_block_db_txn_count:count
synapse_util_metrics_block_db_txn_duration:count
The following are all deprecated, and replaced with synapse_http_server_response_count:

synapse_http_server_response_db_txn_count:count
synapse_http_server_response_db_txn_duration:count
The following are renamed (the old metrics are kept for now, but deprecated):

synapse_http_server_response_db_txn_count
synapse_http_server_response_db_txn_duration:total
synapse_http_server_response_db_txn_duration_seconds
Prometheus handles all metrics as floats, and sometimes we store non-integer
values in them (notably, durations in seconds), so let's render them as floats
too.
(Note that the standard client libraries also treat Counters as floats.)
which was missing its fed client API, since there is no other API
it might as well reuse the bulk one and unwrap it

Turns out that there is a valid usecase for retrieving event by id (notably
having received a push), but event ids should be scoped to room, so /event/{id}
is wrong.
... because these only really exist to confuse people nowadays.
Also bring log config more into line with the generated log config, by making `level_for_storage`
apply to the `synapse.storage.SQL` logger rather than `synapse.storage`.
Add listen_tcp and listen_ssl which implement Twisted's reactor.listenTCP
and reactor.listenSSL for multiple addresses.

Binding on 0.0.0.0 when :: is specified in the bind_addresses is now allowed.
This causes a warning explaining the behaviour.
Configuration changed to match.

Most deployments are on Linux (or Mac OS), so this would actually bind
on both IPv4 and IPv6.
