adeca79d1c Modify evttype_index_ruleset to derive from indexable_ruleset 
Modify evttype_index_ruleset to derive from indexable_ruleset instead
of having its own implementation of segregating filters by ruleset
id/event type.

An evttype_index_wrapper contains a falco rule and filter, and
implements the methods required by the template. run_wrappers()
evaluate the filter as before, without the segregation by ruleset
id/event type.

bbcfa61d82 Add an indexable ruleset that can split filters by ruleset/evttype 
Now that custom rules loading implementations (and related, custom
rulesets) can be swapped into falco in a customizable way, there is
some functionality in evttype_index_ruleset that could be used by
other rulesets, specifically the part that segregates filters by
ruleset and enables/disables filters based on name substring + tags.

To allow for this, create a new template indexable_ruleset<class
filter_wrapper> which derives from filter_ruleset and segregates the
filter_wrappers by ruleset. It also optionally segregates
filter_wrappers by event type.

The filter_wrapper class is an object that can return a name, tags,
and sc/event codes.

The main interfaces for classes that derive from indexable_ruleset are:

- add_wrapper(), which provides a filter_wrapper to the
  indexable_ruleset. This is generally called from
  add()/add_compile_output(), which must be implemented by the derived class.
- run_wrappers(), which must be implemented by the derived class and
  is called for event processing.

Most of the methods required by filter_ruleset are implemented by
indexable_ruleset and do not need to be implemented by the derived
class.
