This diff implements the first two cleanups defined at https://github.com/ooni/probe/issues/1956:
> - [ ] observe that `netxlite` and `netx` differ in error wrapping only in the way in which we set `ErrWrapper.Operation`. Observe that the code using `netxlite` does not care about such a field. Therefore, we can modify `netxlite` to set such a field using the code of `netx` and we can remove `netx` specific code for errors (which currently lives inside of the `./internal/engine/legacy/errorsx` package
>
> - [ ] after we've done the previous cleanup, we can make all the classifiers code private, since there's no code outside `netxlite` that needs them
A subsequent diff will address the remaining cleanup.
While there, notice that there are failing, unrelated obfs4 tests, so disable them in short mode. (I am confident these tests are unrelated because they fail for me when running test locally from the `master` branch.)
Since https://github.com/ooni/probe-cli/pull/527, if an experiment
returns an error, the corresponding measurement is not submitted since
the semantics of returning an error is that something fundamental
went wrong (e.g., we could not parse the input URL).
This diff ensures that all experiments only return and error when
something fundamental was wrong and return nil otherwise.

## Description
This PR contains a set of changes to move important interfaces and data types into the `./internal/model` package.
The criteria for including an interface or data type in here is roughly that the type should be important and used by several packages. We are especially interested to move more interfaces here to increase modularity.
An additional side effect is that, by reading this package, one should be able to understand more quickly how different parts of the codebase interact with each other.
This is what I want to move in `internal/model`:
- [x] most important interfaces from `internal/netxlite`
- [x] everything that was previously part of `internal/engine/model`
- [x] mocks from `internal/netxlite/mocks` should also be moved in here as a subpackage
Here we're refactoring stunreachability to not provide internally a
default input and to take in input an URL rather than a string.
The related ooni/spec change is https://github.com/ooni/spec/pull/227.
This diff has been extracted from https://github.com/ooni/probe-cli/pull/539.
Because the original diff was large, I'm splitting it in a set of
more easily manageable diffs.
The reference issue is https://github.com/ooni/probe/issues/1814, which
is complex enough to require us to proceed incrementally.
This diff WILL need to be backported to release/3.11.
We need still to add similar wrappers to internal/netxlite but we
will adopt a saner approach to error wrapping this time.
See https://github.com/ooni/probe/issues/1591
* fix(pkg.go.dev): import a subpackage containing the assets
We're trying to fix this issue that pkg.go.dev does not build.
Thanks to @hellais for this very neat idea! Let's keep our
fingers crossed and see whether it fixes!
* feat: use embedded geoip databases
Closes https://github.com/ooni/probe/issues/1372.
Work done as part of https://github.com/ooni/probe/issues/1369.
* fix(assetsx): add tests
* feat: simplify and just vendor uncompressed DBs
* remove tests that seems not necessary anymore
* fix: run go mod tidy
* Address https://github.com/ooni/probe-cli/pull/260/files#r605181364
* rewrite a test in a better way
* fix: gently cleanup the legacy assetsdir
Do not remove the whole directory with brute force. Just zap the
files whose name we know. Then attempt to delete the legacy directory
as well. If not empty, just fail. This is fine because it means the
user has stored other files inside the directory.
* fix: create .miniooni if missing
This is how I did it:
1. `git clone https://github.com/ooni/probe-engine internal/engine`
2. ```
(cd internal/engine && git describe --tags)
v0.23.0
```
3. `nvim go.mod` (merging `go.mod` with `internal/engine/go.mod`
4. `rm -rf internal/.git internal/engine/go.{mod,sum}`
5. `git add internal/engine`
6. `find . -type f -name \*.go -exec sed -i 's@/ooni/probe-engine@/ooni/probe-cli/v3/internal/engine@g' {} \;`
7. `go build ./...` (passes)
8. `go test -race ./...` (temporary failure on RiseupVPN)
9. `go mod tidy`
10. this commit message
Once this piece of work is done, we can build a new version of `ooniprobe` that
is using `internal/engine` directly. We need to do more work to ensure all the
other functionality in `probe-engine` (e.g. making mobile packages) are still WAI.
