[PATCH 86/97] curl: Keep pointer to the CURLState in CURLSocket

[Michael Roth]

From: Max Reitz <address@hidden>

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.
