cache: add hashtable cache for object

This patch adds a hashtable for object lookups.

This patch also splits table->objs in two:

- Sets that reside in the cache are stored in the new
  tables->cache_obj and tables->cache_obj_ht.

- Set that defined via command line / ruleset file reside in
  tables->obj.

Sets in the cache (already in the kernel) are not placed in the
table->objs list.

By keeping separated lists, objs defined via command line / ruleset file
can be added to cache.
