Robert Watson e183f80e54 Sync from MAC tree: break out the single mmap entry point into 
seperate entry points for each occasion:

mac_check_vnode_mmap()		Check at initial mapping
mac_check_vnode_mprotect()	Check at mapping protection change
mac_check_vnode_mmap_downgrade()	Determine if a mapping downgrade
					should take place following
					subject relabel.

Implement mmap() and mprotect() entry points for labeled vnode
policies.  These entry points are currently not hooked up to the
VM system in the base tree.  These changes improve the consistency
of the access control interface and offer more flexibility regarding
limiting access to vnode mmaping.
