cache: add hashtable cache for sets
This patch adds a hashtable for set lookups.
This patch also splits table->sets in two:
- Sets that reside in the cache are stored in the new
tables->cache_set and tables->cache_set_ht.
- Set that defined via command line / ruleset file reside in
tables->set.
Sets in the cache (already in the kernel) are not placed in the
table->sets list.
By keeping separated lists, sets defined via command line / ruleset file
can be added to cache.
Adding 10000 sets, before:
# time nft -f x
real 0m6,415s
user 0m3,126s
sys 0m3,284s
After:
# time nft -f x
real 0m3,949s
user 0m0,743s
sys 0m3,205s
