From: Michael Haggerty <mhagger@xxxxxxxxxxxx>
This purely textual change is in preparation for storing references
hierarchically, when the old ref_array structure will represent one
"directory" of references. Rename functions that deal with this
structure analogously, and also rename the structure's "refs" member
to "entries".
