When enabling the account validity feature, Synapse will look at startup for registered account without an expiration date, and will set one equals to 'now + validity_period' for them. On large servers, it can mean that a large number of users will have the same expiration date, which means that they will all be sent a renewal email at the same time, which isn't ideal.
In order to mitigate this, this PR allows server admins to define a 'max_delta' so that the expiration date is a random value in the [now + validity_period ; now + validity_period + max_delta] range. This allows renewal emails to be progressively sent over a configured period instead of being sent all in one big batch.
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.
If account validity is enabled in the server's configuration, this job will run at startup as a background job and will stick an expiration date to any registered account missing one.
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.

We will later need also to import 'register_servlets' from the
'login' module, so we un-pollute the namespace now to keep the
logical changes separate.
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.
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.
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.

Currently the handling of auto_join_rooms only works when a user
registers itself via public register api. Registrations via
registration_shared_secret and ModuleApi do not work
This auto_joins the users in the registration handler which enables
the auto join feature for all 3 registration paths.
This is related to issue #2725

Since we're not doing refresh tokens any more, we should start killing off the
dead code paths. /tokenrefresh itself is a bit of a thornier subject, since
there might be apps out there using it, but we can at least not generate
refresh tokens on new logins.
This doesn't cover *all* of the registration flows, but it does cover the most
common ones: in particular: shared_secret registration, appservice
registration, and normal user/pass registration.
Pull device_id from the registration parameters. Register the device in the
devices table. Associate the device with the returned access and refresh
tokens. Profit.
* `RegistrationHandler.appservice_register` no longer issues an access token:
instead it is left for the caller to do it. (There are two of these, one in
`synapse/rest/client/v1/register.py`, which now simply calls
`AuthHandler.issue_access_token`, and the other in
`synapse/rest/client/v2_alpha/register.py`, which is covered below).
* In `synapse/rest/client/v2_alpha/register.py`, move the generation of
access_tokens into `_create_registration_details`. This means that the normal
flow no longer needs to call `AuthHandler.issue_access_token`; the
shared-secret flow can tell `RegistrationHandler.register` not to generate a
token; and the appservice flow continues to work despite the above change.
This is meant to be an *almost* non-functional change, with the exception that
it fixes what looks a lot like a bug in that it only calls
`auth_handler.add_threepid` and `add_pusher` once instead of three times.
The idea is to move the generation of the `access_token` out of
`registration_handler.register`, because `access_token`s now require a
device_id, and we only want to generate a device_id once registration has been
successful.
This tracks data about the entity which made the request. This is
instead of passing around a tuple, which requires call-site
modifications every time a new piece of optional context is passed
around.
I tried to introduce a User object. I gave up.
This follows the same flows-based flow as regular registration, but as
the only implemented flow has no requirements, it auto-succeeds. In the
future, other flows (e.g. captcha) may be required, so clients should
treat this like the regular registration flow choices.
