Implement a generic copy rte flow API as described in RFC:
http://patches.dpdk.org/patch/85384/

This API allows copying a specified number of bits from a source
header field to a destination header field. Tag, mark or metadata
can also be used as a source/destination to allow saving/overwriting
an arbitrary header field with a user-specified value.

Outermost/innermost packet fields (and Tag array elements) are
accessible via the level parameter to facilitate the modification
of encapsulated packet header fields. The offset parameter provides
the flexibility to copy/set any part of a packet starting the
specified packet header field.
