Make it clearer that #synapse:matrix.org is our support channel (#7379) 
This PR moves the "support is in #synapse:matrix.org" in the bug report template outside of the comment as some people seem to ignore what's in the comments, and phrase it a bit more like the support request template. It also adds a default issue template that says the same thing. It's also adding a notice about the security disclosure to both the default template and the bug report one.

It also adds a badge to the top of the README with an alt text saying about the same message if the badge doesn't load (e.g. if matrix.org is slow).

Fixes #6826

Config option to inhibit 3PID errors on /requestToken 
Adds a request_token_inhibit_errors configuration flag (disabled by
default) which, if enabled, change the behaviour of all /requestToken
endpoints so that they return a 200 and a fake sid if the 3PID was/was
not found associated with an account (depending on the endpoint),
instead of an error.

Attempt to clarify Python version requirements (#7161) 
In particular, we depend on `typing.TYPE_CHECKING`, which is only present in
3.5.2.

It turns out that Ubuntu Xenial, despite having a package called `python 3
(3.5.1-3)`, actually has python 3.5.2, so I think this is fine.

229eb81498 Synapse 1.12.0 (2020-03-23) 
===========================
 
 No significant changes since 1.12.0rc1.
 
 Debian packages and Docker images are rebuilt using the latest versions of
 dependency libraries, including Twisted 20.3.0. **Please see security advisory
 below**.
 
 Security advisory
 -----------------
 
 Synapse may be vulnerable to request-smuggling attacks when it is used with a
 reverse-proxy. The vulnerabilties are fixed in Twisted 20.3.0, and are
 described in
 [CVE-2020-10108](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10108)
 and
 [CVE-2020-10109](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10109).
 For a good introduction to this class of request-smuggling attacks, see
 https://portswigger.net/research/http-desync-attacks-request-smuggling-reborn.
 
 We are not aware of these vulnerabilities being exploited in the wild, and
 do not believe that they are exploitable with current versions of any reverse
 proxies. Nevertheless, we recommend that all Synapse administrators ensure that
 they have the latest versions of the Twisted library to ensure that their
 installation remains secure.
 
 * 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 1.12.0 installed: these images include
   Twisted 20.3.0.
 * Administrators who have [installed Synapse from
   source](https://github.com/matrix-org/synapse/blob/master/INSTALL.md#installing-from-source)
   should upgrade Twisted within their virtualenv by running:
   ```sh
   <path_to_virtualenv>/bin/pip install 'Twisted>=20.3.0'
   ```
 * Administrators who have installed Synapse from distribution packages should
   consult the information from their distributions.
 
 The `matrix.org` Synapse instance was not vulnerable to these vulnerabilities.
 
 Advance notice of change to the default `git` branch for Synapse
 ----------------------------------------------------------------
 
 Currently, the default `git` branch for Synapse is `master`, which tracks the
 latest release.
 
 After the release of Synapse 1.13.0, we intend to change this default to
 `develop`, which is the development tip. This is more consistent with common
 practice and modern `git` usage.
 
 Although we try to keep `develop` in a stable state, there may be occasions
 where regressions creep in. Developers and distributors who have scripts which
 run builds using the default branch of `Synapse` should therefore consider
 pinning their scripts to `master`.
 
 Synapse 1.12.0rc1 (2020-03-19)
 ==============================
 
 Features
 --------
 
 - Changes related to room alias management ([MSC2432](https://github.com/matrix-org/matrix-doc/pull/2432)):
   - Publishing/removing a room from the room directory now requires the user to have a power level capable of modifying the canonical alias, instead of the room aliases. ([\#6965](https://github.com/matrix-org/synapse/issues/6965))
   - Validate the `alt_aliases` property of canonical alias events. ([\#6971](https://github.com/matrix-org/synapse/issues/6971))
   - Users with a power level sufficient to modify the canonical alias of a room can now delete room aliases. ([\#6986](https://github.com/matrix-org/synapse/issues/6986))
   - Implement updated authorization rules and redaction rules for aliases events, from [MSC2261](https://github.com/matrix-org/matrix-doc/pull/2261) and [MSC2432](https://github.com/matrix-org/matrix-doc/pull/2432). ([\#7037](https://github.com/matrix-org/synapse/issues/7037))
   - Stop sending m.room.aliases events during room creation and upgrade. ([\#6941](https://github.com/matrix-org/synapse/issues/6941))

Merge tag 'v1.12.0'

Synapse 1.12.0 (2020-03-23)
===========================

No significant changes since 1.12.0rc1.

Debian packages and Docker images are rebuilt using the latest versions of
dependency libraries, including Twisted 20.3.0. **Please see security advisory
below**.

Security advisory
-----------------

Synapse may be vulnerable to request-smuggling attacks when it is used with a
reverse-proxy. The vulnerabilties are fixed in Twisted 20.3.0, and are
described in
[CVE-2020-10108](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10108)
and
[CVE-2020-10109](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10109).
For a good introduction to this class of request-smuggling attacks, see
https://portswigger.net/research/http-desync-attacks-request-smuggling-reborn.

We are not aware of these vulnerabilities being exploited in the wild, and
do not believe that they are exploitable with current versions of any reverse
proxies. Nevertheless, we recommend that all Synapse administrators ensure that
they have the latest versions of the Twisted library to ensure that their
installation remains secure.

* 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 1.12.0 installed: these images include
  Twisted 20.3.0.
* Administrators who have [installed Synapse from
  source](https://github.com/matrix-org/synapse/blob/master/INSTALL.md#installing-from-source)
  should upgrade Twisted within their virtualenv by running:
  ```sh
  <path_to_virtualenv>/bin/pip install 'Twisted>=20.3.0'
  ```
* Administrators who have installed Synapse from distribution packages should
  consult the information from their distributions.

The `matrix.org` Synapse instance was not vulnerable to these vulnerabilities.

Advance notice of change to the default `git` branch for Synapse
----------------------------------------------------------------

Currently, the default `git` branch for Synapse is `master`, which tracks the
latest release.

After the release of Synapse 1.13.0, we intend to change this default to
`develop`, which is the development tip. This is more consistent with common
practice and modern `git` usage.

Although we try to keep `develop` in a stable state, there may be occasions
where regressions creep in. Developers and distributors who have scripts which
run builds using the default branch of `Synapse` should therefore consider
pinning their scripts to `master`.

Synapse 1.12.0rc1 (2020-03-19)
==============================
