#28638 new Cleanup/optimization

Allow `is_safe_url` to work without `allowed_hosts` or make the parameter mandatory

>>> from django.utils.http import is_safe_url

>>> is_safe_url("")

>>> is_safe_url("", allowed_hosts={""})

If this may have an impact on security, then make it clear that allowed_hosts is mandatory by removing its None default value

The host argument has been optional since the original commit that added is_safe_url() (a2f2a399566dd68ce7e312fff5a5ba857066797d) -- now the parameter is named allowed_hosts. Django always provides that argument -- I'm not sure if there's a use case for not providing it. Did you have something in mind, Florian?

Not that I can think of, we could default allowed_hosts to settings.ALLOWED_HOSTS but I am not sure if that is a good idea given that we can have star in there.
