xtables: Introduce per table chain caches
Being able to omit the previously obligatory table name check when
iterating over the chain cache might help restore performance with large
rulesets in xtables-save and -restore.
There is one subtle quirk in the code: flush_chain_cache() did free the
global chain cache if not called with a table name but didn't if a table
name was given even if it emptied the chain cache. In other places,
chain_cache being non-NULL prevented a cache update from happening, so
this patch establishes the same behaviour (for each individual chain
cache) since otherwise unexpected cache updates lead to weird problems.
