version 2 - Force an abi break. Network mediation will only be
available in v8 abi complaint policy.
Provide a basic mediation of sockets. This is not a full net mediation

application, along with setting up some basic infrastructure for
network mediation to follow.

This reverts commit 651e28c5537abb39076d3949fb7618536f1d242e.
This caused a regression:
"The specific problem is that dnsmasq refuses to start on openSUSE Leap
42.2. The specific cause is that and attempt to open a PF_LOCAL socket
gets EACCES. This means that networking doesn't function on a system
with a 4.14-rc2 system."
Sadly, the developers involved seemed to be in denial for several weeks
about this, delaying the revert. This has not been a good release for
the security subsystem, and this area needs to change development
practices.
