Moves the warning about password resets being disabled to the point where a user actually tries to reset their password. Is this an appropriate place for it to happen?
Also removed the disabling of msisdn password resets when you don't have an email config, as that just doesn't make sense.
Also change the error a user receives upon disabled passwords to specify that only email-based password reset is disabled.
Sends password reset emails from the homeserver instead of proxying to the identity server. This is now the default behaviour for security reasons. If you wish to continue proxying password reset requests to the identity server you must now enable the email.trust_identity_server_for_password_resets option.
This PR is a culmination of 3 smaller PRs which have each been separately reviewed:
* #5308
* #5345
* #5368
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.

Replaces DEFAULT_ROOM_VERSION constant with a method that first checks the config, then returns a hardcoded value if the option is not present.
That hardcoded value is now located in the server.py config file.
We checked that 3pids were not already in use before we checked if
we were going to return the account previously registered in the
same UI auth session, in which case the 3pids will definitely
be in use.

It's more natural for the user if the bit that takes them away
from the registration flow comes last. Adding the dummy stage allows
us to do the stages in this order without the ambiguity.
This allows the client to complete the email last which is more
natual for the user. Without this stage, if the client would
complete the recaptcha (and terms, if enabled) stages and then the
registration request would complete because you've now completed a
flow, even if you were intending to complete the flow that's the
same except has email auth at the end.
Adding a dummy auth stage to the recaptcha-only flow means it's
always unambiguous which flow the client was trying to complete.
Longer term we should think about changing the protocol so the
client explicitly says which flow it's trying to complete.

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.
By default the homeserver will use the identity server used during the
binding of the 3PID to unbind the 3PID. However, we need to allow
clients to explicitly ask the homeserver to unbind via a particular
identity server, for the case where the 3PID was bound out of band from
the homeserver.
Implements MSC915.
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.

This allows registration to be handled by a worker, though the actual
write to the database still happens on master.
Note: due to the in-memory session map all registration requests must be
handled by the same worker.
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.
* Clean up the CSS for the fallback login form
I was finding this hard to work with, so simplify a bunch of things. Each
flow is now a form inside a div of class login_flow.
The login_flow class now has a fixed width, as that looks much better than each
flow having a differnt width.
* Support m.login.sso
MSC1721 renames m.login.cas to m.login.sso. This implements the change
(retaining support for m.login.cas for older clients).
* changelog
Currently when fetching state groups from the data store we make two
hits two the database: once for members and once for non-members (unless
request is filtered to one or the other). This adds needless load to the
datbase, so this PR refactors the lookup to make only a single database
hit.
Broadly three things here:
* disable W504 which seems a bit whacko
* remove a bunch of `as e` expressions from exception handlers that don't use
them
* use `r""` for strings which include backslashes
Also, we don't use pep8 any more, so we can get rid of the duplicate config
there.

This just fixed the errcode on /room_keys/version if no backup and
updates the schema delta to be on the latest so it gets run
Older identity servers may not support the unbind 3pid request, so we
shouldn't fail the requests if we received one of 400/404/501. The
request still fails if we receive e.g. 500 responses, allowing clients
to retry requests on transient identity server errors that otherwise do
support the API.
Fixes#3661
Make sure that the user has permission to view the requeseted event for
/event/{eventId} and /room/{roomId}/event/{eventId} requests.
Also check that the event is in the given room for
/room/{roomId}/event/{eventId}, for sanity.
parse_integer and parse_string can take a request and raise errors
in case we have wrong or missing params.
This PR tries to use them more to deduplicate some code and make it
better readable
The transaction cache has some code which tries to stop it caching failures,
but if the callback function failed straight away, then things would happen
backwards and we'd end up with the failure stuck in the cache.
(instead of everywhere that writes a response. Or rather, the subset of places
which write responses where we haven't forgotten it).
This also means that we don't have to have the mysterious version_string
attribute in anything with a request handler.
Unfortunately it does mean that we have to pass the version string wherever we
instantiate a SynapseSite, which has been c&ped 150 times, but that is code
that ought to be cleaned up anyway really.
This closes#2602
v1auth was created to account for the differences in status code between
the v1 and v2_alpha revisions of the protocol (401 vs 403 for invalid
tokens). However since those protocols were merged, this makes the r0
version/endpoint internally inconsistent, and violates the
specification for the r0 endpoint.
This might break clients that rely on this inconsistency with the
specification. This is said to affect the legacy angular reference
client. However, I feel that restoring parity with the spec is more
important. Either way, it is critical to inform developers about this
change, in case they rely on the illegal behaviour.

The API is now under
/groups/$group_id/setting/m.join_policy
and expects a JSON blob of the shape
```json
{
"m.join_policy": {
"type": "invite"
}
}
```
where "invite" could alternatively be "open".
