I don't know what a suitable one would be. Right now, it appears the
libssh2 code only check for 0 and EAGAIN, all else are just handled
under generic errors. For example, in session.c there is this:
        if (rc == PACKET_EAGAIN) {
            return LIBSSH2_ERROR_EAGAIN;
        } else if (rc) {

Given how the code appears to work, EIO would be as good as any other
code. However, if in the future the library returns more specific
reasons for errors, or does different retries based on the errors,
then something different would be needed, possibly like how curl
handles it: by defining (and sometimes redefining) all the socket
error codes to the the WSA codes in a header file.
