Creates `zerver.lib.url_redirects.py` to record old and new URLs
for documentation pages that have been renamed/moved and need URL
redirects.
This file is then used by `zproject.urls.py` to redirect links and
by `zerver.test.test_urls.py` to test that all of the old URLs
return a success response with a common page header/text depending
on the type of redirect (help center, policy, or API).
Adds a section to contributor docs on writing documentation for
how to use this redirect system when renaming a help center or api
documentation page.
Fixes#21946. Fixes#17897.
We should rearrange Zulip's developer docs to make it easier to
find the documentation that new contributors need.
Name changes
Rename "Code contribution guide" section -> "Contributing to Zulip".
Rename "Contributing to Zulip" page -> "Contributing guide".
Organizational changes to the newly-named "Contributing to Zulip":
Move up "Contributing to Zulip", as the third link in sidebar index.
Move up renamed "Contributing guide" page to the top of this section.
Move up "Zulip code of Conduct", as the second link of this section.
Move down "Licensing", as the last link of this section.
Move "Accessibility" just below "HTML and CSS" in Subsystems section.
Update all links according to the changes above.
Redirects should be added as needed.
Fixes: #22517.
This module was originally introduced in 2016 to assist adding mypy
annotations to the project. Back then static type checking was not that
established throughout the codebase, so it was helpful to be able to
print out the types for type checking purposes.
This workflow is no longer helpful for improving type annotations right
now, and it has been unused for a while.

This is not a feature intended to be used outside zulip.com, since it
just sets your server to have the zulip.com landing pages. I think
it's only been turned on by people who were confused by this text.
We'll be merging a lot more features for the 6.0 release, but this
should cover everything merged since 5.0 and not backported to 5.x
and thus already released.
distutils is deprecated in Python 3.10 and will be removed in Python
3.12. We don’t need a full-powered version parser for this anyway.

Adds a section for writing and style guidlines to the tutorial
for writing help center articles. Moves the sections on 'Voice'
and 'User interface' to be in the new section, and adds a section
on 'Keyboard shortcuts'.
The default value in uwsgi is 4k; receiving more than this amount from
nginx leads to a 502 response (though, happily, the backend uwsgi does not
terminate).
ab18dbfde5 originally increased it from the unstated uwsgi default
of 4096, to 8192; b1da797955 made it configurable, in order to allow
requests from clients with many cookies, without causing 502's[1].
nginx defaults to a limitation of 1k, with 4 additional 8k header
lines allowed[2]; any request larger than that returns a response of
`400 Request Header Or Cookie Too Large`. The largest header size
theoretically possible from nginx, by default, is thus 33k, though
that would require packing four separate headers to exactly 8k each.
Remove the gap between nginx's limit and uwsgi's, which could trigger
502s, by removing the uwsgi configurability, and setting a 64k size in
uwsgi (the max allowable), which is larger than nginx's default limit.
uWSGI's documentation of `buffer-size` ([3], [4]) also notes that "It
is a security measure too, so adapt to your app needs instead of
maxing it out." Python has no security issues with buffers of 64k,
and there is no appreciable memory footprint difference to having a
larger buffer available in uwsgi.

The content in `zulip-config.md` was moved (in #22315) to
`change-zulip-config.file.md`. This removes the now out-of-date
reference to this macro in the documentation for writing
integrations and removes the file as it is no longer in use.
markdown-include is GPL licensed.
Also, rewrite it as a block processor, so that it works correctly
inside indented blocks.

Since python-debian is GPL licensed, our script that imports it should
arguably be GPL licensed as well.

Backups are written every 16k of WAL archive, and by default do not
have an upper limit on how out of date they are, as `archive_timeout`
defaults to 0.
Also emphasize that these are streaming backups, not just one
point-in-time backup daily.
Fixes#21976.
Notable changes:
- Describe `X-Forwarded-For` by name.
- Switch each specific proxy to numbered steps.
- Link back to the `X-Forwarded-For` section in each proxy
- Default to using HTTPS, not HTTP, for the backend.
- Include the HTTP-to-HTTPS redirect code for all proxies; it is
important that it happen at the proxy, as the backend is unaware of
it.
- Call out Apache2 modules which are necessary.
- Specify where the dhparam.pem file can be found.
- Call out the `Host:` header forwarding necessary, and document
`USE_X_FORWARDED_HOST` if that is not possible.
- Standardize on 20 minutes of connection timeout.
Our current EC2 systems don’t have an interface named ‘eth0’, and if
they did, this script would do nothing but crash with ImportError
because we have never installed boto.utils for Python 3.
(The message of commit 2a4d851a7c made
an effort to document for future researchers why this script should
not have been blindly converted to Python 3. However, commit
2dc6d09c2a (#14278) was evidently
unresearched and untested.)

As a consequence:
• Bump minimum supported Python version to 3.8.
• Move Vagrant environment to Ubuntu 20.04, which has Python 3.8.
• Move CI frontend tests to Ubuntu 20.04.
• Move production build test to Ubuntu 20.04.
• Move 3.4 upgrade test to Ubuntu 20.04.
