While there, export DecodeReply to decode a raw reply without
interpreting the Rcode or parsing the results, which seems a
nice extra feature to have to more flexibly parse DNS replies
in other parts of the codebase.
This error occurred for example when querying kazemjalali.com
in websteps measurements run from Iran.
This error is relatively uncommon, but it still makes sense to
create a specific mapping rule for it.

1. we now need to name the framework `.xcframework` otherwise
gomobile refuses to build a new framework for us ¯\_(ツ)_/¯
2. remove duplicate errno definition for iOS (iOS and darwin
are considered the same, therefore we don't need iOS defs)

This diff WILL need to be forwardported to master.
This commit forward ports 74947dbbd12266c12a38fad51a70fc78a21720fd from
the `release/3.11` branch to `master`. Here's the original commit message:
- - -
Android is also Linux. The Android build fails because both
errno_linux.go and errno_android.go are compiled.
There's no difference between the files except into a comment
that mentions "linux" or "android".
Therefore, it's safe to remove the android-specific file
and just keep and use the linux-specific one.
Part of https://github.com/ooni/probe/issues/1863, where we're
forward porting ooni/go patches to go1.17.
I'm still trying to figure out whether I can build oonimkall
using the forward ported patches and this error prevents me
from building, because the build fails.
"やれやれだぜ"
Note that this patch WILL need to be forward ported to master.
This bug was previosuly reported to me by @hellais.
Because I did run `go generate ./internal/netxlite/...` we also
get for free updated certificates, which is OK.
On Windows, GetAddrInfoW is a syscall and the Go resolver does
not attempt to map errors beyond WSA_HOST_NOT_FOUND, which becomes
"no such host", which we map to "dns_nxdomain_error".
See https://github.com/golang/go/blob/go1.17.1/src/net/lookup_windows.go#L16.
To map more GetAddrInfoW errors, thus, we need to enhance our
error classifier to have system specific errors.
Then, we need to filter for the WSA errors that are most likely
to pop up and map them to OONI failures. Those are three:
- WSANO_DATA which we have from our own UDP resolver as well
and which we can map to `dns_no_answer`
- WSANO_RECOVERY which we don't have but existed for MK so
we will use `dns_non_recoverable_failure`, which was an MK error
- WSATRY_AGAIN which likewise we map to the error that MK
used to emit, so `dns_temporary_failure`
This diff should address https://github.com/ooni/probe/issues/1467.
I need to run test on Windows and I just discovered that:
1. the `errno_unix.go` filename does not mean anything because
`unix` is not a valid platform, so we need a filename for
each platform that we care about;
2. on Windows we need to use WSA prefixed names;
3. `i/e/session_psiphon.go` was not building because of the
migration from `netxlite/iox` to `netxlite`.
This diff attempts to fix all three issues.
The reference issue is https://github.com/ooni/probe/issues/1733,
because I was working on such an issue.
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.
Part of https://github.com/ooni/probe/issues/1591
No functional change, as it's clearly obvious from the output.
While there, also rename the generator for certifi. We are planning
on merging errorsx into netxlite. The first step is to give different
names to the code generating programs.

## Description
This PR continues the refactoring of `netx` under the following principles:
1. do not break the rest of the tree and do not engage in extensive tree-wide refactoring yet
2. move under `netxlite` clearly related subpackages (e.g., `iox`, `netxmocks`)
3. move into `internal/netxlite/internal` stuff that is clearly private of `netxlite`
4. hide implementation details in `netxlite` pending new factories
5. refactor `tls` code in `netxlite` to clearly separate `crypto/tls` code from `utls` code
After each commit, I run `go test -short -race ./...` locally. Each individual commit explains what it does. I will squash, but this operation will preserve the original commit titles, so this will give further insight on each step.

* refactor: rename netxmocks -> netxlite/mocks

* refactor: rename quicx -> netxlite/quicx

* refactor: rename iox -> netxlite/iox
Regenerate sources and make sure the tests pass.

* refactor(iox): move MockableReader to netxlite/mocks
See https://github.com/ooni/probe/issues/1591
* refactor(netxlite): generator is an implementation detail
See https://github.com/ooni/probe/issues/1591
* refactor(netxlite): separate tls and utls code
See https://github.com/ooni/probe/issues/1591
* refactor(netxlite): hide most types but keep old names as legacy
With this change we avoid breaking the rest of the tree, but we start
hiding some implementation details a bit. Factories will follow.
