refactor: merge dnsx and errorsx into netxlite (#517) 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.

fix(netxlite): map additional GetAddrInfoW errors (#521) 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.

netxlite: call getaddrinfo and handle platform-specific oddities (#764) This commit changes our system resolver to call getaddrinfo directly when CGO is enabled. This change allows us to: 1. obtain the CNAME easily 2. obtain the real getaddrinfo retval 3. handle platform specific oddities such as `EAI_NODATA` returned on Android devices See https://github.com/ooni/probe/issues/2029 and https://github.com/ooni/probe/issues/2029#issuecomment-1140258729 in particular. See https://github.com/ooni/probe/issues/2033 for documentation regarding the desire to see `getaddrinfo`'s retval. See https://github.com/ooni/probe/issues/2118 for possible follow-up changes.
