A followup change to tcp_request_sock_op would have to drop the 'const'
qualifier from the 'route_req' function as the
'security_inet_conn_request' call is moved there - and that function
expects a 'struct sock *'.
However, it turns out its also possible to add a const qualifier to
security_inet_conn_request instead.

audit_log_string() was inteded to be an internal audit function and
since there are only two internal uses, remove them. Purge all external
uses of it by restructuring code to use an existing audit_log_format()
or using audit_log_format().

The newly added code fails to build when either SECMARK or
NETFILTER are disabled:
security/apparmor/lsm.c: In function 'apparmor_socket_sock_rcv_skb':
security/apparmor/lsm.c:1138:12: error: 'struct sk_buff' has no member named 'secmark'; did you mean 'mark'?
security/apparmor/lsm.c:1671:21: error: 'struct nf_hook_state' declared inside parameter list will not be visible outside of this definition or declaration [-Werror]
Add a set of #ifdef checks around it to only enable the code that
we can compile and that makes sense in that configuration.

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
but just whether a spcific family of socket can be used by an
application, along with setting up some basic infrastructure for
network mediation to follow.

This reverts commit 651e28c553.
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.
