Adds note about updating dh-virtualenv once we drop support for Xenial.
We can't update now, because it needs debhelper 12, while Xenial only
backports 10.

`distutils` is pretty much deprecated these days, and replaced with
`setuptools`. It's also annoying because it's you can't `pip install` it, and
it's hard to figure out which debian package we should depend on to make sure
it's there.
Since we only use it for a tiny function anyway, let's just vendor said
function into our codebase.
Debian package builds were failing for two reasons:
1. Python versions prior to 3.7 throw exceptions when attempting to print
Unicode characters under a "C" locale. (#9076)
2. We depended on `dh-systemd` which no longer exists in Debian Bullseye, but
is necessary in Ubuntu Xenial. (#9073)
Setting `LANG="C.UTF-8"` in the build environment fixes the first issue.
See also: https://bugs.python.org/issue19846
The second issue is a bit trickier. The dh-systemd package was merged into
debhelper version 9.20160709 and a transitional package left in its wake.
The transitional dh-systemd package was removed in Debian Bullseye.
However, Ubuntu Xenial ships an older debhelper, and still needs dh-systemd.
Thus, builds were failing on Bullseye since we depended on a package which had
ceased existing, but we couldn't remove it from the debian/control file and our
build scripts because we still needed it for Ubuntu Xenial.
We can fix the debian/control issue by listing dh-systemd as an alternative to
the newer versions of debhelper. Since dh-systemd declares that it depends on
debhelper, Ubuntu Xenial will select its older dh-systemd which will in turn
pull in its older debhelper, resulting in no change from the status quo. All
other supported releases will satisfy the debhelper dependency constraint and
skip the dh-systemd alternative.
Build scripts were fixed by unconditionally attempting to install dh-systemd on
all releases and suppressing failures.
Once we drop support for Ubuntu Xenial, we can revert most of this commit and
rely on the version constraint on debhelper in debian/control.

===========================
Due to the two security issues highlighted below, server administrators are
encouraged to update Synapse. We are not aware of these vulnerabilities being
exploited in the wild.
Security advisory
-----------------
The following issues are fixed in v1.23.1 and v1.24.0.
- There is a denial of service attack
([CVE-2020-26257](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-26257))
against the federation APIs in which future events will not be correctly sent
to other servers over federation. This affects all servers that participate in
open federation. (Fixed in [#8776](https://github.com/matrix-org/synapse/pull/8776)).
- Synapse may be affected by OpenSSL
[CVE-2020-1971](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-1971).
Synapse administrators should ensure that they have the latest versions of
the cryptography Python package installed.
To upgrade Synapse along with the cryptography package:
* Administrators using the [`matrix.org` Docker
image](https://hub.docker.com/r/matrixdotorg/synapse/) or the [Debian/Ubuntu
packages from
`matrix.org`](https://github.com/matrix-org/synapse/blob/master/INSTALL.md#matrixorg-packages)
should ensure that they have version 1.24.0 or 1.23.1 installed: these images include
the updated packages.
* Administrators who have [installed Synapse from
source](https://github.com/matrix-org/synapse/blob/master/INSTALL.md#installing-from-source)
should upgrade the cryptography package within their virtualenv by running:
```sh
<path_to_virtualenv>/bin/pip install 'cryptography>=3.3'
```
* Administrators who have installed Synapse from distribution packages should
consult the information from their distributions.
Bugfixes
--------
- Fix a bug in some federation APIs which could lead to unexpected behaviour if different parameters were set in the URI and the request body. ([\#8776](https://github.com/matrix-org/synapse/issues/8776))
Internal Changes
----------------
- Add a maximum version for pysaml2 on Python 3.5. ([\#8898](https://github.com/matrix-org/synapse/issues/8898))

After https://github.com/matrix-org/synapse/pull/8377, the deb packages no longer indirectly installed the `"test"` dependencies, causing debian packages to fail to build while carrying out the unit tests.
This PR installs `test` dependencies explicitly when building debian packages.

This ensures systemctl start matrix-synapse returns only after synapse
is actually started, which is very useful for automated deployments.
Fixes#5761
Signed-off-by: Dexter Chua <dec41@srcf.net>
This is basically a contrived way of adding a `Recommends` on `libpq5`, to fix#5653.
The way this is supposed to happen in debhelper is to run
`dh_shlibdeps`, which in turn runs `dpkg-shlibdeps`, which spits things out
into `debian/<package>.substvars` whence they can later be included by
`control`.
Previously, we had disabled `dh_shlibdeps`, mostly because `dpkg-shlibdeps`
gets confused about PIL's interdependent objects, but that's not really the
right thing to do and there is another way to work around that.
Since we don't always use postgres, we don't necessarily want a hard Depends on
libpq5, so I've actually ended up adding an explicit invocation of
`dpkg-shlibdeps` for `psycopg2`.
I've also updated the build-depends list for the package, which was missing a
couple of entries.
* implement `reload` by sending the HUP signal
According to the 0.99 release info* synapse now uses the HUP signal to reload certificates:
> Synapse will now reload TLS certificates from disk upon SIGHUP. (#4495, #4524)
So the matrix-synapse.service unit file should include a reload directive.

In the debian package, make the virtualenv symlink python to /usr/bin/python3.X
rather than /usr/bin/python3. Also make sure we depend on the right python3.x
package.
This might help a bit with subtle failures when people install a package from
the wrong distro (https://github.com/matrix-org/synapse/issues/4431).
