Anders Kaseorg b7b7475672 python: Use standard secrets module to generate random tokens.
There are three functional side effects:

• Correct an insignificant but mathematically offensive bias toward
repeated characters in generate_api_key introduced in commit
47b4283c4b4c70ecde4d3c8de871c90ee2506d87; its entropy is increased
from 190.52864 bits to 190.53428 bits.

• Use the base32 alphabet in confirmation.models.generate_key; its
entropy is reduced from 124.07820 bits to the documented 120 bits, but
now it uses 1 syscall instead of 24.

• Use the base32 alphabet in get_bigbluebutton_url; its entropy is
reduced from 51.69925 bits to 50 bits, but now it uses 1 syscall
instead of 10.

(The base32 alphabet is A-Z 2-7.  We could probably replace all of
these with plain secrets.token_urlsafe, since I expect most callers
can handle the full urlsafe_b64 alphabet A-Z a-z 0-9 - _ without
problems.)

Anders Kaseorg 365fe0b3d5 python: Sort imports with isort.
Fixes #2665.

Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.

Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start.  I expect this change will increase pressure for us to split
those files, which isn't a bad thing.

clarammdantas edcf4f0ea2 invitations: Revoke remaining invitations after user registers.
If a user receives more than one invite to join a
realm, after that user registers, all the remaining
invitations should be revoked, preventing them to be
listed in active invitations on admin panel.
To do this, we added a new prereg_user status,
STATUS_REVOKED.

We also added a confirmation_link_expired_error page
in case the user tries click on a revoked invitaion.
This page has a link to login page.

Fixes: #12629

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 3abb52476c confirmation: Add database indexes on confirmation fields.
Apparently, we didn't have any database indexes on Confirmation, which
meant that on servers with large numbers of users like zulipchat.com,
new account registration could spend a ton of time effectively doing a
table scan on this table.

Raymond Akornor d00b889402 auth: Add an organization reactivation flow with admin confirmation.
This adds a web flow and management command for reactivating a Zulip
organization, with confirmation from one of the organization
administrators.

Further work is needed to make the emails nicer (ideally, we'd send
one email with all the admins on the `To` line, but the `send_email`
library doesn't support that).

Fixes #10783.

With significant tweaks to the email text by tabbott.

Greg Price 0dceeebd05 create_realm: Refactor to deal ASAP with key record, not string.
Now, there's just one spot at the beginning of the function where we
inspect the string key the user gave us; and after that point, we not
only have validated that string but in fact are working from our own
record that it pointed to, not the string itself.

This simplifies the code a bit, e.g. by not repeatedly searching the
database for the key (and hoping everything agrees so that we keep
getting the same row), and it will simplify adding logic to inspect
row attributes like `presume_email_valid`.

Rishi Gupta fdbe36644e confirmation: Add confirmation_type to get_object_from_key.
This change:

* Prevents weird potential attacks like taking a valid confirmation link
  (say an unsubscribe link), and putting it into the URL of a multiuse
  invite link. I don't know of any such attacks one could do right now, but
  reasoning about it is complicated.

* Makes the code easier to read, and in the case of confirmation/views.py,
  exposes something that needed refactoring anyway (USER_REGISTRATION and
  INVITATION should have different endpoints, and both of those endpoints
  should be in zerver/views/registration, not this file).

- tools/lint
- tools/linter_lib
- tools/lister.py

For the latter two, because they might be yanked away to a separate repo
for general use with other FLOSS projects.
