Change adjc_dir_iterate and cartesian_adjacent_iterate to work properly
with topologies that have different valid and cardinal directions.
  - Both are wrappers for adjc_dirlist_iterate.
  - The lists of valid and cardinal directions is built in init_topology.

Patch by Greg, Ross, and myself in PR#8959, with style, comment, and
variable names changes by me.
