Black 23 enforces some slightly more specific rules about empty line
counts and redundant parenthesis removal, but the result is still
compatible with Black 22.
(This does not actually upgrade our Python environment to Black 23
yet.)

This adds a helper based on testing patterns of using the "queries_captured"
context manager with "assert_length" to check the number of queries
executed for preventing performance regression.
It explains the rationale of checking the query count through an
"AssertionError" and prints the queries captured as assert_length does,
but with a format optimized for displaying the queries in a more
readable manner.

This commit adds the OPTIONAL .realm attribute to Message
(and ArchivedMessage), with the server changes for making new Messages
have this set. Old Messages still have to be migrated to backfill this,
before it can be non-nullable.
Appropriate test changes to correctly set .realm for Messages the tests
manually create are included here as well.
We now complain if a test author sends a stream message
that does not result in the sender getting a
UserMessage row for the message.
This is basically 100% equivalent to complaining that
the author failed to subscribe the sender to the stream
as part of the test setup, as far as I can tell, so the
AssertionError instructs the author to subscribe the
sender to the stream.
We exempt bots from this check, although it is
plausible we should only exempt the system bots like
the notification bot.
I considered auto-subscribing the sender to the stream,
but that can be a little more expensive than the
current check, and we generally want test setup to be
explicit.
If there is some legitimate way than a subscribed human
sender can't get a UserMessage, then we probably want
an explicit test for that, or we may want to change the
backend to just write a UserMessage row in that
hypothetical situation.
For most tests, including almost all the ones fixed
here, the author just wants their test setup to
realistically reflect normal operation, and often devs
may not realize that Cordelia is not subscribed to
Denmark or not realize that Hamlet is not subscribed to
Scotland.
Some of us don't remember our Shakespeare from high
school, and our stream subscriptions don't even
necessarily reflect which countries the Bard placed his
characters in.
There may also be some legitimate use case where an
author wants to simulate sending a message to an
unsubscribed stream, but for those edge cases, they can
always set allow_unsubscribed_sender to True.
A bug in the implementation of the can_forge_sender permission
(previously is_api_super_user) resulted in users with this permission
being able to send messages appearing as if sent by a system bots,
including to other organizations hosted by the same Zulip installation.
- The send message API had a bug allowing an api super user to
use forging to send messages to other realms' streams, as a
cross-realm bot. We fix this most directly by eliminating the
realm_str parameter - it is not necessary for any valid current use
case. The email gateway doesn't use this API despite the comment in
that block suggesting otherwise.
- The conditionals inside access_stream_for_send_message are changed up
to improve security. They were generally not ordered very well,
allowing the function to successfully return due to very weak
acceptance conditions - skipping the higher importance checks that
should lead to raising an error.
- The query count in test_subs is decreased because
access_stream_for_send_message returns earlier when doing its check
for a cross-realm bot sender - some subscription checking queries are
skipped.
- A linkifier test in test_message_dict needs to be changed. It didn't
make much sense in the first place, because it was creating a message
by a normal user, to a stream outside of the user's realm. That
shouldn't even be allowed.
Clock time checks lead to tests that nondeterministically fail when
the CI container is super slow, and there's no good reason this test
in particular needs to do that sort of test in addition to our
standard database query count check (which is already does).
This commit moves TestMessageForIdsDisplayRecipientFetching class which
have tests regarding display_recipient filled in by MessageDict to
test_message_dict.py.
