an app can use to let libcurl only connect to a remote host and then extract
the socket from libcurl. libcurl will then not attempt to do any transfer at
all after the connect is done.

Pass a pointer to a long to receive the last socket used by this curl

libcurl close the socket and cleanup other resources associated with the
handle. (Added in 7.15.2)

application can obtain the most recently used socket for special data
transfers. (Added in 7.15.2)
