@vstinner would you review this PR? If you have no time please let me know anyway.

It is a continuation of #1067 with the following differences:

  1. Support scope_id and flowinfo for IPv6 addresses
  2. Fix tp_traverse to process data structures for TYPE_WRITE_TO and TYPE_READ_FROM modes
  3. Increase buffer size for readfrom from 4KiB to 256Kib (256 is used by selector-based event loops)
  4. Support flow-control for data sending, now proactor implementation has the same functionality as selector-based one.
  5. Convert mutable bytearray and memoryview on writing to immutable bytes. The selector-based implementation does the same already.
  6. Add more tests.

I believe that the Pull Request is written well and ready for merging.

If WSAConnect returns immediately, do we need to release GIL?

Technically it is a syscall.
We have the practice to release GIL on socket.bind() for example

Looks good. Merge with caution as I'm not a Windows expert.
