Homeserver.get_ip_from_request() used to be a bit more complicated, but now it is totally redundant. Let's get rid of it.

SynapseRequest is in danger of becoming a bit of a dumping-ground for "useful stuff relating to Requests",
which isn't really its intention (its purpose is to override render, finished and connectionLost to set up the 
LoggingContext and write the right entries to the request log).

Putting utility functions inside SynapseRequest means that lots of our code ends up requiring a
SynapseRequest when there is nothing synapse-specific about the Request at all, and any old
twisted.web.iweb.IRequest will do. This increases code coupling and makes testing more difficult.

In short: move get_user_agent out to a utility function.

For remote users, only the rooms which the server knows about are returned.
Local users have all of their joined rooms returned.

Factor out the exception handling in the startup code to a utility function,
and fix the some logging and exit code stuff.

These tables are unused, and can be dropped now the schema version has been bumped.

This PR adds the missing user_mapping_provider section in oidc.md

You can't continue using a transaction once an exception has been
raised, so catching and dropping the error here is pointless and just
causes more errors.

I'm not even sure what this was supposed to do, but the fact it has python2isms
and nobody has noticed suggests it's not terribly important.

It doesn't seem to have been used since ff23e5ba.

We were running some linters on some files and some on others. Extract a common
setting and use it everywhere.

This is in preparation for moving `SendToDeviceServlet` off master

Currently `DeviceMessageHandler` only ever exists on master, but that is about to change.

This allows for efficiently finding which users ignore a particular
user.

... for running the tests with no optional deps.

If we are lacking an optional dependency, skip the tests that rely on it.

This can happen when using a split out state database and we've upgraded
the schema version without there being any changes in the state schema.

These may be omitted if not set, but Synapse assumed they would
be in the response.

The last stream token is always known and we do not need to handle none.

An experimental room version ("org.matrix.msc2176") contains
the new redaction rules for testing.

During login, if there are multiple IdPs enabled, offer the user a choice of
IdPs.

* Implement CasHandler.handle_redirect_request

... to make it match OidcHandler and SamlHandler

* Clean up interface for OidcHandler.handle_redirect_request

Make it accept `client_redirect_url=None`.

* Clean up interface for `SamlHandler.handle_redirect_request`

... bring it into line with CAS and OIDC by making it take a Request parameter,
move the magic for `client_redirect_url` for UIA into the handler, and fix the
return type to be a `str` rather than a `bytes`.

* Define a common protocol for SSO auth provider impls

* Give SsoIdentityProvider an ID and register them

* Combine the SSO Redirect servlets

Now that the SsoHandler knows about the identity providers, we can combine the
various *RedirectServlets into a single implementation which delegates to the
right IdP.
