Summary:
The express-session middleware, in its regular configuration, will
only set a cookie response header at the beginninng of a session or
when the session contents have changed. It won't set the header if
only the expiration time is changed. This diff uses a dummy `alive`
field to nudge the middleware into setting the header consistently.

This makes the `core` test operate on a directory outside the
jenkins workspace, so that packages in the workspace don't
interfere with the test and obscure errors.
It also includes a small type fix for the `core` build.

Summary:
- Update cookie module, to support modern sameSite settings
- Add a new cookie, grist_sid_status with less-sensitive value, to let less-trusted subdomains know if user is signed in
- The new cookie is kept in-sync with the session cookie.
- For a user signed in once, allow auto-signin is appropriate.
- For a user signed in with multiple accounts, show a page to select which account to use.
- Move css stylings for rendering users to a separate module.
Test Plan: Added a test case with a simulated Discourse page to test redirects and account-selection page.

Summary:
* Remove adjustSession hack, interfering with loading docs under saml.
* Allow the anonymous user to receive an empty list of workspaces for
the merged org.
* Behave better on first page load when org is in path - this used to
fail because of lack of cookie. This is very visible in grist-core,
as a failure to load localhost:8484 on first visit.
* Mark cookie explicitly as SameSite=Lax to remove a warning in firefox.
* Make errorPages available in grist-core.
This changes the default behavior of grist-core to now start off in
anonymous mode, with an explicit sign-in step available. If SAML is not configured,
the sign-in operation will unconditionally sign the user in as a default
user, without any password check or other security. The user email is
taken from GRIST_DEFAULT_EMAIL if set. This is a significant change, but
makes anonymous mode available in grist-core (which is convenient
for testing) and makes behavior with and without SAML much more consistent.
Test Plan: updated test; manual (time to start adding grist-core tests though!)

Summary:
SAML support had broken due to SameSite changes in browsers. This
makes it work again, and tests it against Auth0 (now owned by Okta).
Logging in and out works. The logged out state is confusing, and may
not be complete. The "Add Account" menu item doesn't work.
But with this, an important part of self-hosting becomes easier.
SAML support works also in grist-core, for site pages, but there
is a glitch on document pages that I'll look into separately.

Summary:
When redirecting to login, it's important to have a valid session set. This was
done by middleware that only applies to home pages. We need to set session to
live when redirecting in case of doc pages too.

Summary:
This changes how user attributes are loaded. They are now loaded
directly from sqlite, with per-session caching. Optimizations
considered but not addressed yet are (1) adding indexes to user attribute
tables and (2) swapping in a thinner sqlite wrapper.
The main benefit of this diff is that changes to user attribute
tables now work. Clients whose user attributes are not changed
see no effect; clients whose user attributes have changed have
their document reloaded.
For the purposes of testing, the diff includes a tweak to
GristWSConnection to be "sticky" to a specific user when reloading
(and support machinery on the server side to honor that). Until
now, if a GristWSConnection reloads, it uses whatever the current
default user is in the cookie-based session, which can change.
This was complicating a test where multiple users were accessing
the same document via different clients with occasional document
reloads.
Code for updating when schema or rule changes happen is moved
around but not improved in any meaningful way in this diff.

Summary:
This adds any parameters in a document url whose key ends in '_'
into a `user.Link` object available in access control formulas
and in setting up characteristic tables.
This allows, for example, sending links to a document that contain
a hard-to-guess token, and having that link grant access to a
controlled part of the document (invoices for a specific customer
for example).
A `user.Origin` field is also added, set during rest api calls,
but is only tested manually at this point. It could be elaborated
for embedding use-cases.

Summary:
This is a prototype for expanding the conditions that can be used in granular ACLs.
When processing ACLs, the following variables (called "characteristics") are now available in conditions:
* UserID
* Email
* Name
* Access (owners, editors, viewers)
The set of variables can be expanded by adding a "characteristic" clause. This is a clause which specifies:
* A tableId
* The name of an existing characteristic
* A colId
The effect of the clause is to expand the available characteristics with all the columns in the table, with values taken from the record where there is a match between the specified characteristic and the specified column.
Existing clauses are generalized somewhat to demonstrate and test the use these variables. That isn't the main point of this diff though, and I propose to leave generalizing+systematizing those clauses for a future diff.
Issues I'm not dealing with here:
* How clauses combine. (The scope on GranularAccessRowClause is a hack to save me worrying about that yet).
* The full set of matching methods we'll allow.
* Refreshing row access in clients when the tables mentioned in characteristic tables change.
* Full CRUD permission control.
* Default rules (part of combination).
* Reporting errors in access rules.
That said, with this diff it is possible to e.g. assign a City to editors by their email address or name, and have only rows for those Cities be visible in their client. Ability to modify those rows, and remain updates about them, remains under incomplete control.

Summary:
For methods other than `GET`, `HEAD`, and `OPTIONS`, allow cookie-based authentication only if a certain custom header is present.
Specifically, we check that `X-Requested-With` is set to `XMLHttpRequest`. This is somewhat arbitrary, but allows us to use https://expressjs.com/en/api.html#req.xhr.
A request send from a browser that sets a custom header will prompt a preflight check, giving us a chance to check if the origin is trusted.
This diff deals with getting the header in place. There will be more work to do after this:
* Make sure that all important endpoints are checking origin. Skimming code, /api endpoint check origin, and some but not all others.
* Add tests spot-testing origin checks.
* Check on cases that authenticate differently.
- Check the websocket endpoint - it can be connected to from an arbitrary site; there is per-doc access control but probably better to lock it down more.
- There may be old endpoints that authenticate based on knowledge of a client id rather than cookies.

Summary: This makes the user's role (owner/editor/viewer) available in ActiveDoc methods. No use of that information is made yet, other than to log it. The bulk of the diff is getting a handle on the various ways the methods can be called, and systematizing it a bit more. In passing, access control is added to broadcasts of document changes, so users who no longer have access to a document do not receive changes if they still have the document open.
Test Plan: existing tests pass; test for broadcast access control added

Summary:
Sharing a document with everyone@ was effective at the api level,
but had two flaws in the web client:
* A logged in user with no access at the org level could not access
a publically shared doc within that org.
* Likewise, for the anonymous user (but for a different reason).
This diff tweaks the web client to permit accessing a doc when
org information is unavailable.
It also changes how redirects happen for the anonymous user when
accessing a doc. They now only happen once it has been confirmed
that the user does not have access to the doc.
