Alex Wang bedf02f45b datapath: Prevent linker error of unknown symbol.
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.
