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.
Fixes#467.

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.
The issue here was that the '.' character was unescaped and the
regex was not anchored with a terminal '$'. This was detected by
Anders Kaseorg.

`/etc/postfix/virtual` is of `regexp:` type, not `hash:` type, so
running `postmap` on it has no effect; we need to reload Postfix when
it changes.
http://www.postfix.org/DATABASE_README.html#detect
In the interest of forcing a reload now, optimize the regexes by
eliding the unanchored `.*`s at the beginnings and ends.

scanf doesn’t accept a number as input, so uh, add a dummy space

What. You can’t give me a bad language and then complain when I write

Delete trailing newlines from all files, except
tools/ci/success-http-headers.txt and tools/setup/dev-motd, where they
are significant, and static/third, where we want to stay close to

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.

This gives us access to typing_extensions.Deque, which was not added
to typing until 3.5.4.
(PROVISION_VERSION is not bumped because the transitive dependency set
in dev.txt hasn’t changed.)

As a result of dropping support for trusty, we can remove our old
pattern of putting `if False` before importing the typing module,
which was essential for Python 3.4 support, but not required and maybe
harmful on newer versions.

Since 204 responses don’t contain a payload body, Content-Type is
neither required nor encouraged (RFC 7231 §3.1.1.5), and ours was
missing a semicolon to boot; Content-Length is expressly
forbidden (RFC 7230 §3.3.2).
Furthermore, these add_header directives were silencing the CORS
headers set in api_headers, because add_header inheritance doesn’t
work the way you think it does, as was known before commit
5614d51afc.

Disable TLS 1.0 and TLS 1.1. (We no longer need to support IE8 on
Windows XP.)
Prefer client-selected cipher order. (Now that all enabled ciphers
provide good security, this allows mobile clients lacking AES hardware
acceleration to pick ChaCha20 for better performance.)
Disable session tickets. (Mozilla discourages them based on
https://www.imperialviolet.org/2013/06/27/botchingpfs.html.)

Since we no longer support Ubuntu Trusty, we no longer need this
backwards-compatibility cruft (which we only kept around to avoid
randomizing configuration for existing systems).
This was only used in Ubuntu 14.04 Trusty.
Removing this also finally lets us simplify our security model

One of smtpd_relay_restrictions or smtpd_recipient_restrictions is
required by postfix ≥ 2.10 (see
http://www.postfix.org/SMTPD_ACCESS_README.html).
This is important for using the email mirror on Ubuntu Bionic.
Our priority hierarchy is:
(1) Tornado and base services like memcached, redis, etc.
(2) Django and message sender queue workers.
(3) Everything else.
Ideally, we'd have something a bit more fine-grained (e.g. some queue
workers are potentially in the sending path, while others aren't), but
this should have a big impact on ensuring Tornado gets the resources
it needs during load spikes.
I think this has a good chance of causing some load spikes that would
previously have resulted in a user-facing delivery delays no longer
having any significant user-facing impact.
Previously, if process_fts_updates ended up very far behind
(e.g. 100,000s of messages), it was unable to recover without doing
some very expensive databsae operations to fetch and then delete the
list of message IDs needing updates. This change fixes that issue by
doing the catch-up work in batches.
Also use psql -e (--echo-queries) in scripts that use ‘set -x’, so
errors can be traced to a specific query from the output.

The commit 87d1809657 changed the time when
digests are sent by 3 hours to account for moving from the US East Coast to the
West Coast, but didn't change the time period exception in the
`check-rabbitmq-queue` script.
