net: add SetKeepAlivePeriod
Sets both the duration from the last data packet to the first
keep alive packet and the duration between keep alive packets to be
the passed duration.
I've tested the function on both Darwin (10.8.4) and 4.2 Linux.
I've compiled (make.bash) for all the OS's and tested (all.bash)
on Darwin and Linux.
