Log:

Add TCP keepalive to MythSocket connections. Patch from Jeff Lu with
small modification suggested by Paul Kendall.

In summary, broken connections should now be closed gracefully after a
system specific timeout. For improved usability the timeout should
probably be reduced.

I think this should still be the fallback for broken connections - a
complete solution would include a 'hearbeat' monitor between
frontends/backends, as has been proposed before, that would detect
broken connections in a timely manner (although, thinking about it, I'm
not sure what additional functionality that provides!).

Closes #7839. See the original ticket for full details.
