  -----------
  Addresses may not be persistent across calls to pas_enumerator_reader

Reviewed by Yusuke Suzuki.

Stores the results of calling the reader function in pas_enumerator_create
locally as opposed to referencing the remote memory. This reduction in
indirection means changes to the enumerating process' mapping of the remote
memory will no longer cause values the enumerator is actively using (such
as the pas_root) to become unmapped.
