curl: use new library-side TCP_KEEPALIVE options 

Use the new library CURLOPT_TCP_KEEPALIVE rather than disabling this via
the sockopt callback. If --keepalive-time is used, apply the value to
CURLOPT_TCP_KEEPIDLE and CURLOPT_TCP_KEEPINTVL.

TCP_KEEPINTVL socket options (meaning Linux, recent AIX, HP-UX and more). This
option has no effect if \fI--no-keepalive\fP is used. (Added in 7.18.0)
If this option is used multiple times, the last occurrence sets the amount.
