Use the built-in HTML escaping of Markup("…{var}…").format(), in order
to allow Semgrep to detect mistakes like Markup("…{var}…".format())
and Markup(f"…{var}…").

This commit adds backend code to set email_address_visibility when
registering a new user. The realm-level default and the value of
source profile gets overridden by the value user selected during
signup.
This uses a more specific type `_StrPromise` to replace `Promise`
providing typing information for lazy translation strings.
In places where the callee evaluates the `_StrPromise` object in all
cases we simply force the evaluation with `str()`. This includes
`JsonableError` that ends up handled by the error handler middleware,
and `internal_send_stream_message` that depends on `check_stream_topic`,
requiring the `topic` to be evaluated anyway. In other siuations, the
callee is expected to be able to handle `StrPromise` explicitly.

Our seat count calculation is different for guest user than normal users
(a number of initial guests are free, and additional marginal guests are
worth 1/5 of a seat) - so these checks we apply when a user is being
invited or signing up need to know whether it's a guest or non-guest
being added.
Commit b945aa3443 (#22604) incorrectly
assumed that Django would run the extra EmailField validators if basic
email address validation passed. Actually, it runs all validators
unconditionally and collects all failures. So email_is_not_disposable
needs to catch email address parsing errors.

This refactors rate limit related functions from `zerver.decorator` to
zerver.lib.rate_limiter.
We conditionally import `RemoteZulipServer`, `RequestNotes`, and
`RateLimitedRemoteZulipServer` to avoid circular dependency.
Most instances of importing these functions from `zerver.decorator` got
updated, with a few exceptions in `zerver.tests.test_decorators`, where
we do want to mock the rate limiting functions imported in
`zerver.decorator`. The same goes with the mocking example in the
"testing-with-django" documentation.

Now that we can assume Python 3.6+, we can use the
email.headerregistry module to replace hacky manual email address
parsing.

We no longer need to access the internal `LANGUAGE_CODE` attribute by
using `django.utils.translation.get_language`.
A test case overriding the translation is added to ensure the password
reset form sending to users requested from a wrong domain is properly
translated.
This is a part of django-stubs refactorings.

We want to avoid logging this kind of potentially sensitive information.
Instead, it's more useful to log ids of the matching accounts on
different subdomains.
These error messages weren't marked for translation.
DEACTIVATED_ACCOUNT_ERROR and PASSWORD_TOO_WEAK_ERROR are used in
several places and imported, so we can't move them to be in-line errors
and we keep them at top-level, marked with gettext_lazy.
Using mark_safe on errors with content in them taken from user-input is
a clearly bad idea. With that said, this code
was not exploitable in the current state, given that username is a value
you have to POST to /login/, and the endpoint is CSRF-protected.
We also remove use of mark_safe from the errors without user input them,
but that are just plaintext and thus don't need it.
Fixes “DeprecationWarning: 'jinja2.Markup' is deprecated and will be
removed in Jinja 3.1. Import 'markupsafe.Markup' instead.”

This replaces the TERMS_OF_SERVICE and PRIVACY_POLICY settings with
just a POLICIES_DIRECTORY setting, in order to support settings (like
Zulip Cloud) where there's more policies than just those two.
With minor changes by Eeshan Garg.
Raising jsonableError in the authentication form was non-ideal because
it took the user to an ugly page with the returned json.
We also add logging of this rare occurence of the scenario being
handled here.
django.utils.translation.ugettext is a deprecated alias of
django.utils.translation.gettext as of Django 3.0, and will be removed
in Django 4.0.

Checking for `validate_email_not_already_in_realm` again (after the
form already did so), but only in the case that the form fails to
validate, means that we may be spending time pushing totally invalid
emails to the DB to check. In the case of emails containing nulls,
this can even trigger a 500 error from PostgreSQL.
Stop calling `validate_email_not_already_in_realm` in the form
validation. The form is currently only used in two places -- in
`accounts_home` and in `maybe_send_to_registration`. The latter is
only called if the address is known to not currently have an account,
so checking in there is unnecessary; and in the former case, we wish
different behaviour (the redirect) than just validation failure, which
is all the validator can do.
Fixes#17015.

Add a `--allow-reserved-subdomain` flag which allows creation of
reserved keyword domains. This also always enforces that the domain
is not in use, which was removed in 0258d7d.
Fixes#16924.
This simplifies the code, as it allows using the mechanism of converting
JsonableErrors into a response instead of having separate, but
ultimately similar, logic in RateLimitMiddleware.
We don't touch tests here because "rate limited" error responses are
already verified in test_external.py.
