All (almost?) protocols use the ff_neterrno() macro, which is defined, on
windows, as:

#define ff_neterrno() (-WSAGetLastError())

It could become:

static inline int ff_neterrno(void)
{
    int err = -WSAGetLastError();
    return err == -WSAEWOULDBLOCK ? AVERROR(EAGAIN) : err;
}

This would become a good place for similar mappings should they become
necessary in the future.
