Core: added support for TCP keepalive parameters on macOS.
The support first appeared in OS X Mavericks 10.9 and documented since
OS X Yosemite 10.10.
It has a subtle implementation difference from other operating systems
in that the TCP_KEEPALIVE socket option (used in place of TCP_KEEPIDLE)
isn't inherited from a listening socket to an accepted socket.
An apparent reason for this behaviour is that it might be preserved for
the sake of backward compatibility. The TCP_KEEPALIVE socket option is
not inherited since appearance in OS X Panther 10.3, which long predates
two other TCP_KEEPINTVL and TCP_KEEPCNT socket options.
Thanks to Andy Pan for initial work.
