* tls_handshakes: add IP addresses
* tls_handshakes: extract ip from tcp-connect
* tls_handshake: switched to trace event
* saver.go: get remoteAddr before handshake
Not sure whether this is strictly necessary, but I'd rather take the
remoteAddr before calling Handshake, just in case a future version
of the handshake closes the `conn`. In such a case, `conn.RemoteAddr`
would return `nil` and we would crash here.
This occurred to me while reading once again the diff before merging.

We recently started moving core data structures inside of the
internal/model package as detailed in https://github.com/ooni/probe/issues/1885.
The chief reason to do that is to have a set of fundamental
shared data types to help us rationalize the codebase.
This specific diff moves internal/netx/archival's core data types
inside the internal/model package. While there, it also refactors the
existing tests to improve their quality. Additionally, we also added
an extra test to ensure `ArchivalHTTPBody` is an alias for
`ArchivalMaybeBinaryData`, which is required to ensure the
custom JSON serialization process works for it.
We're doing that because both internal/netx/archival and
internal/measurex define their own archival data structures.
We developed measurex using its own structures because it
allowed to iterate more quickly. Now that we have sketched
out measurex, the time has come to consolidate.
My overall aim is to spend a few more hours this week on
engineering measurex. This work is preliminary work before
we finish up both measurex and websteps.
We described this cleanup in https://github.com/ooni/probe/issues/1957.
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.)

## 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
When preparing a tutorial for netxlite, I figured it is easier
to tell people "hey, this is the package you should use for all
low-level networking stuff" rather than introducing people to
a set of packages working together where some piece of functionality
is here and some other piece is there.

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
The legacy part for now is internal/errorsx. It will stay there until
I figure out whether it also needs some extra bug fixing.
The good part is now in internal/netxlite/errorsx and contains all the
logic for mapping errors. We need to further improve upon this logic
by writing more thorough integration tests for QUIC.
We also need to copy the various dialer, conn, etc adapters that set
errors. We will put them inside netxlite and we will generate errors in
a way that is less crazy with respect to the major operation. (The
idea is to always wrap, given that now we measure in an incremental way
and we don't measure every operation together.)

We are not using them anymore. The only nettest still using the
legacy netx implementation is tor, for which setting these fields
is useless, because it performs each measurement into a separate
goroutine. Hence, let us start removing this part of the legacy
netx codebase, which is hampering progress in other areas.
Occurred to me while doing testing for the recent changes in
error mapping (https://github.com/ooni/probe/issues/1505).
* 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
* fix(webconnectivity): expose network events
By not exposing network events in webconnectivity, we are missing
several interesting, explanatory data points.
This diff fixes the issue by:
1. enriching the definition of network events to include extra
data useful for performing (manual) data analysis;
2. adding a tags field to network events such that we can add
tags to specific events and understand where they come from;
3. exposing all the (tagged) network events that happen when running
a webconnectivity experiment.
See https://github.com/ooni/probe-engine/issues/1157.
* progress
* more work towards landing this diff
* Apply suggestions from code review
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.
