src: split chain list in table

This patch splits table->lists in two:

- Chains that reside in the cache are stored in the new
  tables->cache_chain and tables->cache_chain_ht. The hashtable chain
  cache allows for fast chain lookups.

- Chains that defined via command line / ruleset file reside in
  tables->chains.

Note that chains in the cache (already in the kernel) are not placed in
the table->chains.

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