Summary: As suggested by @dsagal in https://phab.getgrist.com/D3277#inline-36801, change to query `SUM(pgsize - unused)` instead of `SUM(pgsize)` to measure actual data size more accurately. Technically this doesn't reflect the database file size as accurately, but it should reflect sandbox memory usage better, and more importantly it should allow users to see data size decreasing when they delete stuff.
Test Plan: Tested manually by adding rows to a doc and looking at the logs. The data size is smaller and changes more granularly.

Summary:
- Small cleanup: Make DocStorage implement OnDemandStorage, and remove unused execWithBackup
- Upgrade to new versions (.3) of @gristlabs/sqlite3 and connect-sqlite3 to use dbstat
- Add _logDataSize method which queries dbstat, adding up pgsize for tables loaded into the data engine
- Only complete _logDataSize every 5 minutes using new field _lastLoggedDataSize
Test Plan: Tested manually

Summary:
Finishing imports now occurs in Node instead of the
data engine, which makes it possible to import into
on-demand tables. Merging code was also refactored
and now uses a SQL query to diff source and destination
tables in order to determine what to update or add.
Also fixes a bug where incremental imports involving
Excel files with multiple sheets would fail due to the UI
not serializing merge options correctly.
Test Plan: Browser tests.

Summary:
This makes it possible to set the type of a column to ReferenceList, but the UI is terrible
ReferenceList.ts is a mishmash of ChoiceList and Reference that sort of works but something about the CSS is clearly broken
ReferenceListEditor is just a text editor, you have to type in a JSON array of row IDs. Ignore the value that's present when you start editing. I can maybe try mashing together ReferenceEditor and ChoiceListEditor but it doesn't seem wise.
I think @georgegevoian should take over here. Reviewing the diff as it is to check for obvious issues is probably good but I don't think it's worth trying to land/merge anything.
Test Plan: none

Summary:
This applies some mitigations suggested by SQLite authors when
opening untrusted SQLite databases, as we do when Grist docs
are uploaded by the user. See:
https://www.sqlite.org/security.html#untrusted_sqlite_database_files
Steps implemented in this diff are:
* Setting `trusted_schema` to off
* Running a SQLite-level integrity check on uploads
Other steps will require updates to our node-sqlite3 fork, since they
are not available via the node-sqlite3 api (one more reason to migrate
to better-sqlite3).
I haven't yet managed to create a file that triggers an integrity
check failure without also being detected as corruption by sqlite
at a more basic level, so that is a TODO for testing.
Test Plan:
existing tests pass; need to come up with exploits to
actually test the defences and have not yet

Summary:
- Update rules to be more like we've had with tslint
- Switch tsserver plugin to eslint (tsserver makes for a much faster way to lint in editors)
- Apply suggested auto-fixes
- Fix all lint errors and warnings in core/, app/, test/
Test Plan: Some behavior may change subtly (e.g. added missing awaits), relying on existing tests to catch problems.

Summary:
This fixes DocStorage.fetchQuery when the number of parameters
exceeds the maximum that can be passed directly to sqlite.
In this case, parameters are now stored and used from a temporary
table.
Problem first noticed via a use of DocStorage.fetchQuery by
granular access controls. Access control should be optimized
to make fewer such queries, but that is a separate issue.

Summary:
Previously in {{D1053}} we switched to using BLOB as the "type" for all columns, to prevent SQLite from casting data unexpectedly. This diff now returns to more meaningful types. We apply marshalling to values when being placed in a column where a cast might occur, to inhibit such casting.
The benefit is that Grist documents become easier to interact with via regular database clients/libraries, which often rely on the column type more than a purely SQLite tool would.
On column type conversion, we run all blobs in the column through a decode/encode cycle so if they no longer need to be marshalled they revert to native type. This could be optimized further, it is somewhat brute force.
Test Plan: Updated tests and reference document

Summary:
Loading all user data to run a migration is risky (creates more than usual
memory pressure), and almost never needed (only one migration requires it).
This diff attempts to run migrations using only metadata (_grist_* tables),
but retries if the sandbox tells it that all data is needed.
The intent is for new migrations to avoid needing all data.
Test Plan: Added a somewhat contrived unittest.

Summary:
- Introduce a new SQLiteDB migration, which adds DB columns for formula columns
- Newly added columns have the special ['P'] (pending) value in them
(in order to show the usual "Loading..." on the first load that triggers the migration)
- Calculated values are added to .stored/.undo fields of user actions.
- Various changes made in the sandbox to include .stored/.undo in the right order.
- OnDemand tables ignore stored formula columns, replacing them with special SQL as before
- In particular, converting to OnDemand table leaves stale values in those
columns, we should maybe clean those out.
Some tweaks on the side:
- Allow overriding chai assertion truncateThreshold with CHAI_TRUNCATE_THRESHOLD
- Rebuild python automatically in watch mode
Test Plan: Fixed various tests, updated some fixtures. Many python tests that check actions needed adjustments because actions moved from .stored to .undo. Some checks added to catch situations previously only caught in browser tests.

Summary:
Deliberate changes:
* save snapshots to s3 prior to migrations.
* label migration snapshots in s3 metadata.
* avoid pruning migration snapshots for a month.
Opportunistic changes:
* Associate document timezone with snapshots, so pruning can respect timezones.
* Associate actionHash/Num with snapshots.
* Record time of last change in snapshots (rather than just s3 upload time, which could be a while later).
This ended up being a biggish change, because there was nowhere ideal to put tags (list of possibilities in diff).
