qemu/curl-Keep-pointer-to-the-CURLState-in-CU.patch

Subject: curl: Keep pointer to the CURLState in CURLSocket

Git-commit: 0487861685294660b23bc146e1ebd5304aa8bbe0

A follow-up patch will make curl_multi_do() and curl_multi_read() take a
CURLSocket instead of the CURLState.  They still need the latter,
though, so add a pointer to it to the former.
