selinux: wrap AVC state
Wrap the AVC state within the selinux_state structure and
pass it explicitly to all AVC functions. The AVC private state
is encapsulated in a selinux_avc structure that is referenced
from the selinux_state.
This change should have no effect on SELinux behavior or
APIs (userspace or LSM).
