This makes it relatively easy for a system administrator to
temporarily override these values after a desktop app security
release that they want to ensure all of their users take.
We're not putting this in settings, since we don't want to encourage
accidental long-term overrides of these important-to-security values.
This allows us to block use of the desktop app with insecure versions
(we simply fail to load the Zulip webapp at all, instead rendering an
error page).
For now we block only versions that are known to be both insecure and
not auto-updating, but we can easily adjust these parameters in the
future.
Users who are using ZulipDesktop or haven't managed to auto-update to
ZulipElectron should be strongly encouraged to upgrade.
We'll likely want to move to something even stricter that blocks
loading the app at all, but this is a good start.
This fixes a confusing aspect of how our automated tests worked
previously, where we'd almost all HTTP requests in the unlikely
configuration with no User-Agent string specified.
We need to adjust query counts in a few tests that now are a bit
cheaper because they now can take advantage of a Client object created
in server_initialization.py in `process_client`.
Previous cleanups (mostly the removals of Python __future__ imports)
were done in a way that introduced leading newlines. Delete leading
newlines from all files, except static/assets/zulip-emoji/NOTICE,
which is a verbatim copy of the Apache 2.0 license.

In a quick scan of today's nginx logs on chat.zulip.org, there
were 20 distinct user-agents that begin with 'ZulipMobile/'.
Here's a representative sampling of them, such that the rest
were all boringly similar to one of these.
First, to make room for these without an excess of copy-paste and
overlong lines, convert this test to a data-oriented style. The
existing, synthetic cases appear in the new data followed by the
seen-in-the-wild cases.
Happily, the code being tested passes all these new cases unchanged.
This release is from 2018-08-22, a little over 100 days ago.
It was the first release with the important fix so that when the
server advises it to stop displaying a notification because the user
has read the message (as the SEND_REMOVE_PUSH_NOTIFICATIONS server
setting enables), the app doesn't instead replace the notification
with a broken one reading "null". We have that setting running now
on chat.zulip.org, and intend to roll it out more broadly soon.
The `# take 0` thing is a slightly absurd workaround for the fact
that our funky out-of-line way of marking lines to ignore doesn't
work right if there are multiple such lines in a given file that
are equal modulo leading and trailing whitespace.
