bd6a54e901 (core) mitigate csrf by requiring custom header for unsafe methods
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.

986f469965 (core) Support "Public access" switch in the UI for docs.
Summary:
- The older "Anonymous access" option is renamed to "Public access" in the UI.
- This option was only present with GRIST_SUPPORT_ANON set.
- With GRIST_SUPPORT_ANON, the old behavior is kept: "Public access"
  option adds/removes anon@ user
- Without GRIST_SUPPORT_ANON (normal case), orgs/workspaces don't support
  "Public access" option. For documents, it adds/removes everyone@ user.

The latter is the main feature of interest. The GRIST_SUPPORT_ANON flag
is set for on-premise installs, and adds discoverability by anon users.

Test Plan: Added a test cases and checks in other tests.

87f2fd15fb (core) add more detail to /compare endpoint
Summary:
 * Extends `/api/docs/docId1/compare/docId2` endpoint with a `detail=1` option to include details of what changed in the document content.
 * Adds an `/api/docs/docId/compare?left=HASH&right=HASH` endpoint for comparing two versions of a single document. This is needed to implement the extension to `/api/docs/docId1/compare/docId2`.
 * Adds a `HashUtil` class to allow hash aliases like `HEAD` and `HEAD~`.

Everything is a bit crude:
 * Changes are expressed as ActionSummary objects, which aren't fully fleshed out.
 * Extra data about formula columns is inserted in an inflexible way.

This is extracted and cleaned up from https://phab.getgrist.com/D2600.

6b24d496db (core) add per-user per-org preferences to database
Summary:
Adds preferences to orgs.  There are a few flavors:
 * `userOrgPrefs`: these are specific to a certain user and a certain org.
 * `orgPrefs`: these are specific to a certain org, and apply to all users.
 * `userPrefs`: these are specific to a certain user, and apply to all orgs.

The three flavors of prefs are reported by `GET` for an org, and can be modified by `PATCH` for an org.  The user needs to have UPDATE rights to change `orgPrefs`, but can change `userOrgPrefs` and `userPrefs` without that right since the settings only affect themselves.

2399baaca2 (core) When saving copies, allow saving to another org; update menus for making and saving copies.
Summary:
- Implemented selecting an org in some cases when using Save-Copy dialog.
- Unified previous 'Save Copy' menu into an enhanced "Share" menu.
- Renamed ExportMenu to ShareMenu, collect related code into it, and design the share button.
- Introduced trunkAccess property for forks, to know whether "Replace Original" is available.
- Simplified handling of fork() result, now that all code has been upgraded.
- Replaced 'Copy as Template' menu items with a checkbox in the Save-Copy dialog
- Removed copy links for examples in the DocMenu (to simplify, since not part of updated design)
- Updated the UI of the copying dialog.

Test Plan: Updated affected tests, added new test cases for copying when other orgs are a choice or not.

5ef889addd (core) move home server into core
Summary: This moves enough server material into core to run a home server.  The data engine is not yet incorporated (though in manual testing it works when ported).

Test Plan: existing tests pass
