Webpack code splitting will make the inclusion order of CSS files less

The url scheme is now /accounts/login/social/saml/{idp_name} to initiate
login using the IdP configured under "idp_name" name.
display_name and display_logo (the name and icon to show on the "Log in
with" button) can be customized by adding the apprioprate settings in
the configured IdP dictionaries.
login_context now gets the social_backends list through
get_social_backend_dicts and we move display_logo customization
to backend class definition.
This prepares for easily adding multiple IdP support in SAML
authentication - there will be a social_backend dict for each configured
IdP, also allowing display_name and icon customization per IdP.
ESLint won’t convert these automatically because it can’t rule out a
behavior difference arising from an access to a self-referential var
before it’s initialized:
> var x = (f => f())(() => x);
undefined
> let y = (f => f())(() => y);
Thrown:
ReferenceError: Cannot access 'y' before initialization

Because of the separate declarations, ESLint would convert them to
`let` and then trigger the `prefer-const` error.

Even though this variable was only assigned once, it was accessed
before its initialization, so it couldn’t be converted directly to
`let` or `const`. Use `let` with an explicit `null` to make it
clearer what’s going on and satisfy ESLint. (Why not `undefined`?
There’s an ESLint rule against that too.)

With webpack, variables declared in each file are already file-local
(Global variables need to be explicitly exported), so these IIFEs are

This changes the way django_to_ldap_username works to make sure the ldap
username it returns actually has a corresponding ldap entry and raise an
exception if that's not possible. It seems to be a more sound approach
than just having it return its best guess - which was the case so far.
Now there is a guarantee that what it returns is the username of an
actual ldap user.
This allows communicating to the registration flow when the email being
registered doesn't belong to ldap, which then will proceed to register
it via the normal email backend flow - finally fixing the bug where you
couldn't register a non-ldap email even with the email backend enabled.
These changes to the behavior of django_to_ldap_username require small
refactorings in a couple of other functions that call it, as well as
adapting some tests to these changes. Finally, additional tests are
added for the above-mentioned registration flow behavior and some
related corner-cases.
This feels a bit more semantically appropriate: it more clearly says
"here's some information: there is no (relevant) recipient", rather
than "no information available". (Both `null` and `undefined` in JS
can have either meaning, but `undefined` especially commonly means
the latter.)
Concretely, it ensures a bit more explicitness where the value
originates: a bare `return;` becomes `return null;`, reflecting the
fact that it is returning a quite informative value.
Also make the implementation more explicit about what's expected here,
replacing truthiness tests with `!== null`. (A bit more idiomatic
would be `!= null`, which is equivalent when the value is well-typed
and a bit more robust to ill-typing bugs. But lint complains about
that version.)
It'd already been the case for some while that calling `stop` had the
same effect as calling `update` (previously `handle_text_input`) with
a falsy recipient. With the API changes in the previous few commits,
this becomes quite natural to make explicit in the API.
This was named after when it gets called from the UI, rather than
after what it can be expected to do.
Naming it after what it's meant to do -- and giving a summary line to
expand on that -- provides a more helpful semantic idea for reasoning
about the function. Doubly so for using the function in a different
client with its own UI, like the mobile app.
The main motivation for this change is to simplify this interface
and make it easier to reason about.
The case where it affects the behavior is when
is_valid_conversation() returns false, while current_recipient
and get_recipient() agree on some truthy value.
This means the message-content textarea is empty -- in fact the
user just cleared it, because we got here from an input event on
it -- but the compose box is still open to some PM thread that we
have a typing notification still outstanding for.
The old behavior is that in this situation we would ignore the
fact that the content was empty, and go ahead and prolong the
typing notification, by updating our timer and possibly sending a
"still typing" notice.
This contrasts with the behavior (both old and new) in the case
where the content is empty and we *don't* already have an
outstanding typing notification, or we have one to some other
thread. In that case, we cancel any existing notification and
don't start a new one, exactly as if `stop` were called
(e.g. because the user closed the compose box.)
The new behavior is that we always treat clearing the input as
"stopped typing": not only in those cases where we already did,
but also in the case where we still have the same recipients.
(Which seems like probably the common case.)
That seems like the preferable behavior; indeed it's hard to see
the point of the "compose_empty" logic if restricted to the other
cases. It also makes the interface simpler.
Those two properties don't seem like a coincidence, either: the
complicated interface made it difficult to unpack exactly what
logic we actually had, which made it easy for surprising wrinkles
to hang out indefinitely.
All these cases are meant to simulate having a user actually typing a
message to some actual recipients, so the `conversation_is_valid`
parameter would be true.
We make this change so that in an upcoming change that eliminates this
parameter, the adjustments to the test cases can be highly regular and
we don't have to introduce a new wrinkle to correspond to these values
being false.
Returning true from this function means we go on to send, or extend
the lifetime of, a typing notification; returning false means we don't.
It's hard to see why having a partially-entered name in the recipient
box should mean we're *more* inclined to send a typing notification to
the set of recipients that are already entered; if anything, it seems
like it should make us *less* inclined to do so. So we're better off
without this conditional.
The conditional was introduced in commit 72295e94b, as part of a
conversion from user emails to user IDs; there, it seems to replace a
condition that went in the opposite direction, returning *false* if
there were any invalid emails in the recipient box. So perhaps it's
just inverted.
Moreover, the (re-)inverted version would also be wrong: if the user
is typing a PM addressed to some users, and they hit send, the message
will go to those users whether or not they have any unconverted text
in the recipients box. So the typing notifications should too.
The real purpose these two callbacks serve is exactly what an ordinary
parameter is perfect for:
* Each has just one call site, at the top of the function.
* They're not done for side effects; the point is what they return.
* The function doesn't pass them any arguments of its own, or
otherwise express any internal knowledge that doesn't just as
properly belong to its caller.
So, push the calls to these callbacks up into the function's caller,
and pass in the data they return instead.
This greatly simplifies the interface of `handle_text_input` and of
`typing_status` in general.
This is intended as a pure refactor, making the data flow clearer in
preparation for further changes. In particular, this makes it
manifest that the calls to `get_recipient` and `is_valid_conversation`
don't depend on anything else that has happened during the call to
`handle_text_input`.
This is indeed a pure refactor because
* is_valid_conversation itself has no side effects, either in the
implementation in typing.js or in any reasonable implementation,
so calling it sooner doesn't affect anything else;
* if we do reach it, the only potentially-side-effecting code it's
moving before is a call to `stop_last_notification`, and that in
turn (with the existing, or any reasonable, implementation of
`notify_server_stop`) has no effect on the data consulted by
the implementation of `is_valid_conversation`.
Apparently deferring our own Bootstrap (commit
f1ecd3c18b, #13164) means that this
surprise copy of Bootstrap 2.3.2 also needs to be deferred. What is
this even doing here.

This has been a spurious alert for a long time.
It's unclear that this check is useful at all, but if it spikes
dramatically above what's normal, there's perhaps still utility in
being alerted.
