Added a get_venv_dependencies() function in setup_venv.py which
returns VENV_DEPENDENCIES according to the vendor and os_version.
The reason for adding this function was because python-dev will be
depreciated in Focal but can be used as python2-dev so when adding
support for Focal VENV_DEPENDENCIES should to be os_version dependent.
isort 5 knows not to reorder imports across function calls, so this
will stop isort from breaking our code.

This adds Ubuntu 19.10 as a valid provisioning target.
The release test in setup-apt-repo was changed from a list of values to
a regex check for brevity.
The “Smileys & People” category has been split into “Smilys & Emotion”
and “People & Body”.
Also, fix generate_sha1sum_emoji to read the emoji-datasource-google
version from yarn.lock, since package.json only gives a version range.

These docstrings hadn't been properly updated in years, and bad an
awkward mix of a bad version of the user-facing documentation and
details that are no longer true (e.g. references to "Voyager").
(One important detail is that we have real documentation for this
system now).
Zulip has had a small use of WebSockets (specifically, for the code
path of sending messages, via the webapp only) since ~2013. We
originally added this use of WebSockets in the hope that the latency
benefits of doing so would allow us to avoid implementing a markdown
local echo; they were not. Further, HTTP/2 may have eliminated the
latency difference we hoped to exploit by using WebSockets in any
case.
While we’d originally imagined using WebSockets for other endpoints,
there was never a good justification for moving more components to the
WebSockets system.
This WebSockets code path had a lot of downsides/complexity,
including:
* The messy hack involving constructing an emulated request object to
hook into doing Django requests.
* The `message_senders` queue processor system, which increases RAM
needs and must be provisioned independently from the rest of the
server).
* A duplicate check_send_receive_time Nagios test specific to
WebSockets.
* The requirement for users to have their firewalls/NATs allow
WebSocket connections, and a setting to disable them for networks
where WebSockets don’t work.
* Dependencies on the SockJS family of libraries, which has at times
been poorly maintained, and periodically throws random JavaScript
exceptions in our production environments without a deep enough
traceback to effectively investigate.
* A total of about 1600 lines of our code related to the feature.
* Increased load on the Tornado system, especially around a Zulip
server restart, and especially for large installations like
zulipchat.com, resulting in extra delay before messages can be sent
again.
As detailed in
https://github.com/zulip/zulip/pull/12862#issuecomment-536152397, it
appears that removing WebSockets moderately increases the time it
takes for the `send_message` API query to return from the server, but
does not significantly change the time between when a message is sent
and when it is received by clients. We don’t understand the reason
for that change (suggesting the possibility of a measurement error),
and even if it is a real change, we consider that potential small
latency regression to be acceptable.
If we later want WebSockets, we’ll likely want to just use Django
Channels.

This simplifies the RDS installation process to avoid awkwardly
requiring running the installer twice, and also is significantly more
robust in handling issues around rerunning the installer.
Finally, the answer for whether dictionaries are missing is available
to Django for future use in warnings/etc. around full-text search not
being great with this configuration, should they be required.
`copytree` throws an error if the target already exists, and we don’t
really want to rerun the copy anyway.

This is needed on at least Debian 10, otherwise xmlsec fails to
install: `Could not find xmlsec1 config. Are libxmlsec1-dev and
pkg-config installed?`
Also remove libxmlsec1-openssl, which libxmlsec1-dev already depends.
(No changes are needed on RHEL, where libxml2-devel and xmlsec1-devel
already declare a requirement on /usr/bin/pkg-config.)

The output log from running clean_unused_caches was too verbose as
part of the `upgrade-zulip` overall output. While this output is
potentially helpful when running it directly for debugging, it's
certainly redundant for the main production use case.
So a new flag --no-print-headers is introduced. It suppresses the
header outputs for the subtools.
Fixes#13214.
This allows the system to get updates to the Groonga repository
signing key, so `apt update` doesn’t start failing when the key
changes (like it recently did).

debian-archive-keyring is a dependency of the essential package apt,
so it is present in every Debian system.

virtualenv on Ubuntu 16.04, when creating a new environment, downloads
the current version of setuptools, then replaces its pkg_resources
with an old copy from
/usr/share/python-wheels/pkg_resources-0.0.0-py2.py3-none-any.whl.
This causes problems, a simple example of which is reproducible from
the ubuntu:16.04 Docker base image as follows:
apt-get update
apt-get -y install python3-virtualenv
python3 -m virtualenv -p python3 /ve
/ve/bin/pip install sockjs-tornado
/ve/bin/pip download sockjs-tornado
→ `AttributeError: '_NamespacePath' object has no attribute 'sort'`
More relevantly, it breaks pip-compile in the same way. To fix this,
we need to force setuptools to be reinstalled, even if we’re asking
for the same version.

We no longer use tsearch_extras, and the camo patch is irrelevant on
systemd systems (Xenial and newer). So we no longer need to

Now that we're implemented tsearch_extras in pure postgres, we no
longer need a custom extension. This should help us considerably, as
it means we no longer need to ship custom apt packages at all.

As predicted in https://www.kb.cert.org/vuls/id/319816/, a malicious
worm is beginning to spread across the npm ecosystem through package
postinstall scripts. Only instead of direct self-replicating code,
the replication vector is the temptation to monetize postinstall
scripts by polluting the console logs with paid advertisements. The
effect will be the same unless we all put a stop to this while we
still can.
Apply the recommended VU#319816 workaround, which is to disable
lifecycle scripts when installing npm packages. The only fallout is:
* node-sass can’t run because it uses compiled native code; we replace
it with Dart Sass.
* phantomjs-prebuilt doesn’t download the binary at install time; we
tell it to download it in run-casper.
* ttf2woff2 transparently falls back from native code to an Emscripten
build.

This commit finishes adding end-to-end support for the install script
on Debian Buster (making it production ready). Some support for this
was already added in prior commits such as
99414e2d96.
We plan to revert the postgres hunks of this once we've built
tsearch_extras for our packagecloud archive.
Fixes#9828.
