Alex Vandiver b14a33c659 thumbnailing: Switch to libvips, from PIL/pillow.
This is done in as much of a drop-in fashion as possible.  Note that
libvips does not support animated PNGs[^1], and as such this
conversion removes support for them as emoji; however, libvips
includes support for webp images, which future commits will take
advantage of.

This removes the MAX_EMOJI_GIF_SIZE limit, since that existed to work
around bugs in Pillow.  MAX_EMOJI_GIF_FILE_SIZE_BYTES is fixed to
actually be 128KiB (not 128MiB, as it actually was), and is counted
_after_ resizing, since the point is to limit the amount of data
transfer to clients.

Zixuan James Li 30495cec58 migration: Rename extra_data_json to extra_data in audit log models.
This migration applies under the assumption that extra_data_json has
been populated for all existing and coming audit log entries.

- This removes the manual conversions back and forth for extra_data
throughout the codebase including the orjson.loads(), orjson.dumps(),
and str() calls.

- The custom handler used for converting Decimal is removed since
DjangoJSONEncoder handles that for extra_data.

- We remove None-checks for extra_data because it is now no longer
nullable.

- Meanwhile, we want the bouncer to support processing RealmAuditLog entries for
remote servers before and after the JSONField migration on extra_data.

- Since now extra_data should always be a dict for the newer remote
server, which is now migrated, the test cases are updated to create
RealmAuditLog objects by passing a dict for extra_data before
sending over the analytics data. Note that while JSONField allows for
non-dict values, a proper remote server always passes a dict for
extra_data.

- We still test out the legacy extra_data format because not all
remote servers have migrated to use JSONField extra_data.
This verifies that support for extra_data being a string or None has not
been dropped.

Steve Howell b742f1241f realm emoji: Use a single cache for all lookups.
The active realm emoji are just a subset of all your
realm emoji, so just use a single cache entry per
realm.

Cache misses should be very infrequent per realm.

If a realm has lots of deactivated realm emoji, then
there's a minor expense to deserialize them, but that
is gonna be dwarfed by all the other more expensive
operations in message-send.

I also renamed the two related functions.  I erred on
the side of using somewhat verbose names, as we don't
want folks to confuse the two use cases. Fortunately
there are somewhat natural affordances to use one or
the other, and mypy helps too.

Finally, I use realm_id instead of realm in places
where we don't need the full Realm object.

Anders Kaseorg 7657cb4a0f django_api: Extract send_event_on_commit helper.
django-stubs 4.2.1 gives transaction.on_commit a more accurate type
annotation, but this exposed that mypy can’t handle the lambda default
parameters that we use to recapture loop variables such as

    for stream_id in public_stream_ids:
        peer_user_ids = …
        event = …

        transaction.on_commit(
            lambda event=event, peer_user_ids=peer_user_ids: send_event(
                realm, event, peer_user_ids
            )
        )

https://github.com/python/mypy/issues/15459

A workaround that mypy accepts is

        transaction.on_commit(
            (
                lambda event, peer_user_ids: lambda: send_event(
                    realm, event, peer_user_ids
                )
            )(event, peer_user_ids)
        )

But that’s kind of ugly and potentially error-prone, so let’s make a
helper function for this very common pattern.

        send_event_on_commit(realm, event, peer_user_ids)

Anders Kaseorg 92ad4455ed requirements: Upgrade Django to 4.1.
zerver/migrations/0240_usermessage_migrate_bigint_id_into_id.py needs
to be updated to account for Django 4.1 creating AutoField as an
identity column rather than a serial column.

We also add acting_user parameter to do_remove_realm_emoji in

Sahil Batra 1307976d34 actions: Pass realm_emoji dict to notify_realm_emoji.
We pass the realm_emoji dict to notify_realm_emoji instead
of computing it in notify_realm_emoji itself, because its
caller functions will require the dict in further commits
for creating RealmAuditLog entries.
