lsm: infrastructure management of the sock security

Browse source 
[ Upstream commit 2aff9d20d5 ]

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.
