Summary:
Currently, we have two ways that we deliver Grist. One is grist-core,
which has simple defaults and is relatively easy for third parties to
deploy. The second is our internal build for our SaaS, which is the
opposite. For self-managed Grist, a planned paid on-premise version
of Grist, I adopt the following approach:
* Use the `grist-core` build mechanism, extending it to accept an
overlay of extra code if present.
* Extra code is supplied in a self-contained `ext` directory, with
an `ext/app` directory that is of same structure as core `app`
and `stubs/app`.
* The `ext` directory also contains information about extra
node dependencies needed beyond that of `grist-core`.
* The `ext` directory is contained within our monorepo rather than
`grist-core` since it may contain material not under the Apache
license.
Docker builds are achieved in our monorepo by using the `--build-context`
functionality to add in `ext` during the regular `grist-core` build:
```
docker buildx build --load -t gristlabs/grist-ee --build-context=ext=../ext .
```
Incremental builds in our monorepo are achieved with the `build_core.sh` helper,
like:
```
buildtools/build_core.sh /tmp/self-managed
cd /tmp/self-managed
yarn start
```
The initial `ext` directory contains material for snapshotting to S3.
If you build the docker image as above, and have S3 access, you can
do something like:
```
docker run -p 8484:8484 --env GRIST_SESSION_SECRET=a-secret \
--env GRIST_DOCS_S3_BUCKET=grist-docs-test \
--env GRIST_DOCS_S3_PREFIX=self-managed \
-v $HOME/.aws:/root/.aws -it gristlabs/grist-ee
```
This will start a version of Grist that is like `grist-core` but with
S3 snapshots enabled. To release this code to `grist-core`, it would
just need to move from `ext/app` to `app` within core.
I tried a lot of ways of organizing self-managed Grist, and this was
what made me happiest. There are a lot of trade-offs, but here is what
I was looking for:
* Only OSS-code in grist-core. Adding mixed-license material there
feels unfair to people already working with the repo. That said,
a possible future is to move away from our private monorepo to
a public mixed-licence repo, which could have the same relationship
with grist-core as the monorepo has.
* Minimal differences between self-managed builds and one of our
existing builds, ideally hewing as close to grist-core as possible
for ease of documentation, debugging, and maintenance.
* Ideally, docker builds without copying files around (the new
`--build-context` functionality made that possible).
* Compatibility with monorepo build.
Expressing dependencies of the extra code in `ext` proved tricky to
do in a clean way. Yarn/npm fought me every step of the way - everything
related to optional dependencies was unsatisfactory in some respect.
Yarn2 is flexible but smells like it might be overreach. In the end,
organizing to install non-core dependencies one directory up from the
main build was a good simple trick that saved my bacon.
This diff gets us to the point of building `grist-ee` images conveniently,
but there isn't a public repo people can go look at to see its source. This
could be generated by taking `grist-core`, adding the `ext` directory
to it, and pushing to a distinct repository. I'm not in a hurry to do that,
since a PR to that repo would be hard to sync with our monorepo and
`grist-core`. Also, we don't have any licensing text ready for the `ext`
directory. So leaving that for future work.

The problem that this diff address is that, the logic to decide what columns we need to keep, only applies to the visible
fields and ignore the hidden columns, causing all hidden columns to be removed. This diff, simply
changes that routine to address all columns.
the mutliple fixes on the test_summary2.py result from a change of
ordering of columns: the culprit is the `group` columns, which is by
default a hidden columns and that had to be explicitely added back to
the new summary table. It is now transferred automatically, like other
columns, which does cause a little change of ordering on the db. This
should not result in any display order changes for the users.

- The document is the same (the docId hash matches)
- The source column still exists and has the same type as when copied
- The source type isn't Text, because in that case it's nice if type guessing still happens
- The target column is empty, meaning it has type Any (we check earlier that it's not a formula column)
The info copied is the type, widgetOptions, and reference column settings (visible and display columns) but not conditional formatting.
The changes are mostly in a function `parsePasteForView` which is based on `BaseView._parsePasteForView` but ported to TypeScript in a new file `BaseView2.ts`.

This adds support for gvisor sandboxing in core. When Grist is run outside of a container, regular gvisor can be used (if on linux), and will run in rootless mode. When Grist is run inside a container, docker's default policy is insufficient for running gvisor, so a fork of gvisor is used that has less defence-in-depth but can run without privileges.
Sandboxing is automatically turned on in the Grist core container. It is not turned on automatically when built from source, since it is operating-system dependent.
This diff may break a complex method of testing Grist with gvisor on macs that I may have been the only person using. If anyone complains I'll find time on a mac to fix it :)

This is a fix for a bug discussed in https://grist.slack.com/archives/C069RUP71/p1645138610722889
I still haven't completely wrapped my head around it or figured out how to make a simple reproducible example, but the problem seems to be that a lookup can happen before the column(s) being looked up (the summary helper column in this case) have been computed fully (I think it got interrupted halfway by an OrderError). `do_lookup` would check via `engine._use_node` that the row IDs it found had all been computed already, but there might still be other rows that hadn't been computed yet and would also have values matching the lookup key, so it missed those.
This diff instead calls `_use_node` with no `row_ids` argument, which should ensure that all rows have already been computed.
At first I was worried about how this would affect performance, which led me down an optimisation rabbit hole, hence a bit of unrelated cleanup here and also https://phab.getgrist.com/D3310 . But it doesn't seem to be a problem, and IIUC it should actually make things better, although this code is pretty confusing.

Summary:
This is an attempt to optimise Engine._use_node. It doesn't seem to actually improve overall performance significantly, but it shouldn't make it worse, and I think it's an improvement to the code.
It turns out that there's no need to track a stack of compute frames any more. The only time we get close to nested evaluation, we set allow_evaluation=False to prevent it actually happening. So there's only one 'frame' during actual evaluation, which means we can get rid of the concept of frames entirely. This allows simplifying the code and letting the computer do less work in general.

Summary:
- Removed string parsing and some type guessing code from parse_data.py. That logic is now implicitly done by ValueGuesser by leaving the initial column type as Any. parse_data.py mostly comes into play when importing files (e.g. Excel) containing values that already have types, i.e. numbers and dates.
- 0s and 1s are treated as numbers instead of booleans to keep imports lossless.
- Removed dateguess.py and test_dateguess.py.
- Changed what `guessDateFormat` does when multiple date formats work equally well for the given data, in order to be consistent with the old dateguess.py.
- Columns containing numbers are now always imported as Numeric, never Int.
- Removed `NullIfEmptyParser` because it was interfering with the new system. Its purpose was to avoid pointlessly changing a column from Any to Text when no actual data was inserted. A different solution to that problem was already added to `_ensure_column_accepts_data` in the data engine in a recent related diff.

- Added 2 `nbrowser/Importer2` tests.
- Updated various existing tests.
- Extended testing of `guessDateFormat`. Added `guessDateFormats` to show how ambiguous dates are handled internally.

This makes a `user.SessionID` value available in information about the user, for use with trigger formulas and granular access rules. The ID should be constant within a browser session for anonymous user. For logged in users it simply reflects their user id.
This ID makes it possible to write access rules and trigger formulas that allow different anonymous users to create, view, and edit their own records in a document.
For example, you could have a brain-storming document for puns, and allow anyone to add to it (without logging in), letting people edit their own records, but not showing the records to others until they are approved by a moderator. Without something like this, we could only let anonymous people add one field of a record, and not have a secure way to let them edit that field or others in the same record.
Also adds a `user.IsLoggedIn` flag in passing.
