Akhil Goyal 2973dbf93b security: hide session structure
Structure rte_security_session is moved to internal
headers which are not visible to applications.
The only field which should be used by app is opaque_data.
This field can now be accessed via set/get APIs added in this
patch.
Subsequent changes in app and lib are made to compile the code.
