Anders Kaseorg df001db1a9 black: Reformat with Black 23. 
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.)

Anders Kaseorg fead14951c python: Convert assignment type annotations to Python 3.6 style. 
This commit was split by tabbott; this piece covers the vast majority
of files in Zulip, but excludes scripts/, tools/, and puppet/ to help
ensure we at least show the right error messages for Xenial systems.

We can likely further refine the remaining pieces with some testing.

Tim Abbott 8e7ce7cc79 python: Sort migrations/management command imports with isort. 
This is a preparatory commit for using isort for sorting all of our
imports, merging changes to files where we can easily review the
changes as something we're happy with.

These are also files with relatively little active development, which
means we don't expect much merge conflict risk from these changes.

Mateusz Mandera 0c2cc41d2e CVE-2019-18933: Fix insecure account creation via social authentication. 
A bug in Zulip's new user signup process meant that users who
registered their account using social authentication (e.g. GitHub or
Google SSO) in an organization that also allows password
authentication could have their personal API key stolen by an
unprivileged attacker, allowing nearly full access to the user's
account.

Zulip versions between 1.7.0 and 2.0.6 were affected.

This commit fixes the original bug and also contains a database
migration to fix any users with corrupt `password` fields in the
database as a result of the bug.

Out of an abundance of caution (and to protect the users of any
installations that delay applying this commit), the migration also
resets the API keys of any users where Zulip's logs cannot prove the
user's API key was not previously stolen via this bug.  Resetting
those API keys will be inconvenient for users:

* Users of the Zulip mobile and terminal apps whose API keys are reset
  will be logged out and need to login again.
* Users using their personal API keys for any other reason will need
  to re-fetch their personal API key.

We discovered this bug internally and don't believe it was disclosed
prior to our publishing it through this commit.  Because the algorithm
for determining which users might have been affected is very
conservative, many users who were never at risk will have their API
keys reset by this migration.

To avoid this on self-hosted installations that have always used
e.g. LDAP authentication, we skip resetting API keys on installations
that don't have password authentication enabled.  System
administrators on installations that used to have email authentication
enabled, but no longer do, should temporarily enable EmailAuthBackend
before applying this migration.

The migration also records which users had their passwords or API keys
reset in the usual RealmAuditLog table.
