1e0430dff9 Make compile_condition() a protected method for use in subclasses 
Move the part of compile_rule_infos that actually compiled a condition
string into a sinsp_filter into a standalone method
compile_condition(). That way it can be used by classes that derive
from rule_loader::compiler() and want to compile condition strings.

This implementation also saves the compiled filter as a part of the
falco_rule object so it does not need to be compiled again wihin the
falco engine after rules loading.

88a57bfd1a Add ability for rulesets to access falco engine state 
Some rulesets may need information which is held by the falco_engine
that created this ruleset. So define a set of functions in a struct
and have setters/getters for those functions in the base class.

Derived classes can use the struct's functions to obtain the falco
engine information.

The only function so far is to obtain the filter_ruleset for a given
event source.
