ofproto-dpif-xlate: Harmonize naming of internal functions.
It would be good to be able to harminize the use of "xlate", "execute",
"compose", etc. "xlate" clearly relates to the use of the various
translation context structures, but the distinction between "execute" and
"compose" is not that clear, so these names could be going either way.
Choose to go with "compose", keeping with the older tradition.
