Add handle to control global TCP keepalives and turn them on as
default.
Despite their name it doesn't keep TCP sessions alive, it kills
them if the other end has gone AWOL. This happens a lot with
clients which use NAT, dynamic IP assignment or which has a 2^32
* 10^-3 seconds upper bound on their uptime.
There is no detectable increase in network trafic because of this:
two minimal TCP packets every two hours for a live TCP connection.
Many servers already enable keepalives themselves.
The host requirements RFC is 10 years old, and doesn't know about
the loosing clients of todays InterNet.
