With the latest change of separating vports into their own modules, it is necessary to export all public functions in linux/compat/ directory. Also, we should prefix functions which replace the upstream ones with 'rpl_' and others with 'ovs_'. This will prevent the linker error when vport modules use those functions in the future. e.g., the to be merged vport-stt module will use the flex_array_* functions which are not currently exported.
