Use a windows specific keepalive function. (#1104)

Use a windows specific keepalive function.

While it is possible to toggle `TCP_KEEPALIVE` in windows via
setsockopt, you have to use `WSAIoctl` to set the interval.

Since `WSAIoctl` can actually do all of this in one call (toggle the
option, and set the corresponding interval), just use that in Windows
and avoid the call to `setsockopt` alltogether.

Fixes: #1100
