Reduce peak memory consumption during FS-related tests, in particular during parallel execution.
Reduce peak memory consumption during FS-related tests, in particular
during parallel execution.

Nothing major here; just follow the common pool usage patterns.  This
also improves the signal-to-noise ratio when using the test suite to
check for pool usage issues in the FS implementations.

* subversion/tests/svn_test_fs.c
  (get_dir_entries): Properly name the pool argument and use an ITERPOOL
                     for iteration and recursion.
  (svn_test__validate_tree): Allocate everything from temporary pools as
                             we don't return anything.  Use an ITERPOOL.
  (svn_test__txn_script_exec,
   svn_test__check_greek_tree,
   svn_test__create_greek_tree_at): Use an ITERPOOL for iteration.
