[PATCH 0/4] Add resize_hash() to hash.c

The first patch is just a couple formatting fixes.

The second patch renames "nelem" to "bucket_count" to hopefully reduce
ambiguity.

The third patch adds a "elem_count" and increments/decrements it on
hash insert/remove.

The last patch is the main one, adding resize_hash().  I am not a hash
expert.  If you have suggestions on the resizing limit, currently:
    if (table->elem_count > table->bucket_count * 1.2)
      resize_hash(table);
or other issues, please don't hesitate to mention them.

Kevin J. McCarthy (4):
  Formatting cleanup in hash.c.
  Rename hash nelem to bucket_count.
  Add elem_count to hash.
  Add resize_hash() function.
