fix(netxlite): robust {ReadAll,Copy}Context with wrapped io.EOF (#661)
* chore(netxlite): add currently failing test case

This diff introduces a test cases that will fail because of the reason
explained in https://github.com/ooni/probe/issues/1965.

* chore(netxlite/iox_test.go): add failing unit tests

These tests directly show how the Go implementation of ReadAll
and Copy has the issue of checking for io.EOF equality.

* fix(netxlite): make {ReadAll,Copy}Context robust to wrapped io.EOF

The fix is simple: we just need to check for `errors.Is(err, io.EOF)`
after either io.ReadAll or io.Copy has returned. When this condition is
true, we need to convert the error back to `nil` as it ought to be.

While there, observe that the unit tests I committed in the previous
commit are wrongly asserting that the error must be wrapped. This
assertion is not correct, because in both cases we have just ensured
that the returned error is `nil` (i.e., success).

See https://github.com/ooni/probe/issues/1965.

* cleanup: remove previous workaround for wrapped io.EOF

These workarounds were partial, meaning that they would cover some
cases in which the issue occurred but not all of them.

Handling the problem in `netxlite.{ReadAll,Copy}Context` is the
right thing to do _as long as_ we always use these functions instead
of `io.{ReadAll,Copy}`.

This is why it's now important to ensure we clearly mention that
inside of the `CONTRIBUTING.md` guide and to also ensure that we're
not using these functions in the code base.

* fix(urlgetter): repair tests who assumed to see EOF error

Now that we have established that we should normalize EOF when
reading bodies like the stdlib does and now that it's clear why
our behavior diverged from the stdlib, we also need to repair
all the tests that assumed this incorrect behavior.

* fix(all): don't use io{,util}.{Copy,ReadAll}

* feat: add checks to ensure we don't use io.{Copy,ReadAll}

* doc(netxlite): document we know how to deal w/ wrapped io.EOF

* fix(nocopyreadall.bash): add exception for i/n/iox.go

refactor: interfaces and data types into the model package (#642)
## Checklist

- [x] I have read the [contribution guidelines](https://github.com/ooni/probe-cli/blob/master/CONTRIBUTING.md)
- [x] reference issue for this pull request: https://github.com/ooni/probe/issues/1885
- [x] related ooni/spec pull request: N/A

Location of the issue tracker: https://github.com/ooni/probe

## 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

[forwardport] fix: avoid http3 for dns.google and www.google.com (#593) (#594)
This commit forward ports dedd84fa7ecb09f718f6b1a9c83999cb37b34dfa.

Original commit message:

- - -

This diff changes code the release/3.11 branch to ensure we're not using dns.google and www.google.com over HTTP3. As documented in https://github.com/ooni/probe/issues/1873, since this morning (approx) these services do not support HTTP3 anymore. (I didn't bother with checking whether this issue affects _other_ Google services; I just limited my analysis to the services that we were using as part of testing.)

This patch WILL require forward porting to the master branch.

fix(netxlite): make test less flaky on macOS (#526)
The explanatory comment in the diff says it all.

Work done while I was converging with https://github.com/ooni/probe/issues/1733.

feat: run ~always netxlite integration tests (#522)
* feat: run ~always netxlite integration tests

This diff ensures that we check on windows, linux, macos that our
fundamental networking library (netxlite) works.

We combine unit and integration tests.

This work is part of https://github.com/ooni/probe/issues/1733, where
I want to have more strong guarantees about the foundations.

* fix(filtering/tls_test.go): make portable on Windows

The trick here is to use the wrapped error so to normalize the
different errors messages we see on Windows.

* fix(netxlite/quic_test.go): make portable on windows

Rather than using the zero port, use the `x` port which fails
when the stdlib is parsing the address.

The zero port seems to work on Windows while it does not on Unix.

* fix(serialresolver_test.go): make error more timeout than before

This seems enough to convince Go on Windows about this error
being really a timeout timeouty timeouted thingie.

refactor: migrate apitool from netx to netxlite (#496)
I discovered which transport were used by apitool and made sure he gets the same transports now. While there, I discovered an issue with ooni/oohttp that has been fixed with cba9b1ce5e.

fix(netxlite): http3 transport needs logging by default (#492)
Adapt other places where it was not using a logger to either choose
a reasonable logger or disable logging for backwards compat.

refactor(netxlite): finish grouping tests (#488)
They are now more readable. I'll do another pass and start
separating integration testing from unit testing.

I think we need to have some always on integration testing
for netxlite that runs on macOS, linux, and windows.
