* SAML2 Improvements and redirect stuff
Signed-off-by: Alexander Trost <galexrt@googlemail.com>
* Code cleanups and simplifications.
Also: share the saml client between redirect and response handlers.
* changelog
* Revert redundant changes to static js
* Move all the saml stuff out to a centralised handler
* Add support for tracking SAML2 sessions.
This allows us to correctly handle `allow_unsolicited: False`.
* update sample config
* cleanups
* update sample config
* rename BaseSSORedirectServlet for consistency
* Address review comments
This fixes a bug which were causing the "event_format" field to be
ignored in the filter of requests to the `/messages` endpoint of the
CS API.

This commit adds two config options:
* `restrict_public_rooms_to_local_users`
Requires auth to fetch the public rooms directory through the CS API and disables fetching it through the federation API.
* `require_auth_for_profile_requests`
When set to `true`, requires that requests to `/profile` over the CS API are authenticated, and only returns the user's profile if the requester shares a room with the profile's owner, as per MSC1301.
MSC1301 also specifies a behaviour for federation (only returning the profile if the server asking for it shares a room with the profile's owner), but that's currently really non-trivial to do in a not too expensive way. Next step is writing down a MSC that allows a HS to specify which user sent the profile query. In this implementation, Synapse won't send a profile query over federation if it doesn't believe it already shares a room with the profile's owner, though.
Groups have been intentionally omitted from this commit.
Adds a new method, check_3pid_auth, which gives password providers
the chance to allow authentication with third-party identifiers such
as email or msisdn.
Currently the explanation message is sent to the abuse room before any
users are forced joined, which means it tends to get lost in the backlog
of joins.
So instead we send the message *after* we've forced joined everyone.
Allow for the creation of a support user.
A support user can access the server, join rooms, interact with other users, but does not appear in the user directory nor does it contribute to monthly active user limits.
This is mostly factoring out the post-CAS-login code to somewhere we can reuse
it for other SSO flows, but it also fixes the userid mapping while we're at it.
* Rip out half-implemented m.login.saml2 support
This was implemented in an odd way that left most of the work to the client, in
a way that I really didn't understand. It's going to be a pain to maintain, so
let's start by ripping it out.
* drop undocumented dependency on dateutil
It turns out we were relying on dateutil being pulled in transitively by
pysaml2. There's no need for that bloat.
