45d2d5f897 (core) back-end support for tables that are accessible only by owners
Summary:
This makes it possible to serve a table or tables only to owners.

 * The _grist_ACLResources table is abused (temporarily) such that rows of the form `{colId: '~o', tableId}` are interpreted as meaning that `tableId` is private to owners.
 * Many websocket and api endpoints are updated to preserve the privacy of these tables.
 * In a document where some tables are private, a lot of capabilities are turned off for non-owners to avoid leaking info indirectly.
 * The client is tweaked minimally, to show '-' where a page with some private material would otherwise go.

No attempt is made to protect data from private tables pulled into non-private tables via formulas.

There are some known leaks remaining:
 * Changes to the schema of private tables are still broadcast to all clients (fixable).
 * Non-owner may be able to access snapshots or make forks or use other corners of API (fixable).
 * Changing name of table makes it public, since tableId in ACLResource is not updated (fixable).

Security will require some work, the attack surface is large.

Test Plan: added tests

2ea8b8d71f (core) After a spate of spurious test failures, try to fix a few.
Summary:
- Disable a pointless timing check in Python that occasionally fails.
- Make the test of InvalidValues more robust by waiting for calculated values to load.
- Make Snapshots test more robust by waiting for an action that precedes a URL change.

Test Plan: These tests should fail less often when the tested logic is correct.

003029bf8a (core) Improve suggestions for formula autocomplete
Summary:
- Make suggestions less case-sensitive (not entirely case-insensitive, but
  allow top-level suggestions to match in all-lowercase)
- Add function signatures to suggestions for Grist functions.
- Excel-like functions that are present but not implemented are no longer
  offered as suggestions.

Test Plan:
Added a test case on python side, and a browser test case for how suggestions
are rendered and inserted.

7a8debae16 (core) Improve object serialization, to help get RECORD data to Custom Widgets.
Summary:
- Change RECORD's dates_as_str default to False.
- Reimplement objtype encode_object/decode_object with less machinery.
- Implement encoding of dicts (with string keys).
- Make lists and dicts encode values recursively.
- Implement encoding/decoding in the client
- Decode automatically in plugins' fetchSelectedTable/Record, with an option to skip.

Test Plan: Tested manually, not sure what tests may be affected yet.

48ca124f23 (core) Render unmarshallable values as non-errors, using their repr() strings.
Summary:
- Instead of sending an "UnmarshallableError" as an exception, introduce an
  "Unmarshallable" type of value, represented as ['U', repr(value)]
- Unmarshallable values are rendered using a bluish text color, no longer a
  pink background.
- Factor out ErrorDom to be simpler and cleaner.
- Add GristObjCode enum, and simplify related helpers.
- Use safe_repr() for when repr() itself fails
- Handle conversion errors using safe_repr() when str() fails

Test Plan: Added a test case based on a fixture covering a bunch of cases.

Dmitry S
4e11b6a922 (core) Implement RECORD function that converts Records to Python dictionaries
Summary:
Examining a Record is currently difficult, because its columns are hard to
list (and to use), and CircularRef errors hard to avoid. The RECORD function
takes care of this mess to return a simple dictionary of values.

- Supports dates_as_iso=False flag to turn off the translation of date/datetime
  objects to strings.
- Supports expand_refs=True flag to apply RECORD() to encountered values of
  type Record, for a single level of nesting.

Test Plan: Added a unittest for RECORD()

Test Plan:
existing tests pass.
Tested core functionality manually.  Tested docker build manually.
