5db61a1623 Add a load_files method to load multiple files at once
Add alternate load_files variants that allow loading multiple files at
once. This is a bit faster than calling load_rules()/load_rules_file()
repeatedly as rules are only compiled once, after reading all rules
files, instead of being compiled after reading each rules file.

01093d2dfc fix(userspace/engine): support both old and new gcc + std::move
Old gcc versions (e.g. 4.8.3) won't allow move elision
but newer versions (e.g. 10.2.1) would complain about
the redundant move.

f2318a9ac5 cleanup(userspace/falco): address reviewers comments + cleanup
* prefix counters and stats belonging to kernel space w/ `k.` else `u.` for userspace
* add n_drops_perc from old stats writer schema
* revert one change: file output shall reflect exact same "output_fields" key as rule output, note that src is already part of the "output_fields" schema.

- avoiding inspector to be allocated for each rule
- use two boolean values for expecting macros and lists
- move items of lists alongside name, under info
- use snake case for json output, like we do for e.g alerts
- correctly retrieve evt names
- consider two levels of lists for exception operators
