lsm: infrastructure management of the sock security

Move management of the sock->sk_security blob out
of the individual security modules and into the security
infrastructure. Instead of allocating the blobs from within
the modules the modules tell the infrastructure how much
space is required, and the space is allocated there.

The cred is needed to properly audit some messages, and will be needed
in the future for uid conditional mediation. So pass it through to

Audit messages currently don't contain the mediation class which can

newer mediation classes coming this potential confusion will become
worse.

Fix this by adding the mediatin class to the messages.

security: add const qualifier to struct sock in various places

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.
