Validate rule outputs when loading rules by attempting to create a
formatter based on the rule's output field. If there's an error, it will
propagate up through load_rules and cause falco to exit rather than
discover the problem only when trying to format the event and the rule's
output field.
This required moving formats.{cpp,h} into the falco engine directory
from the falco general directory. Note that these functions are loaded
twice in the two lua states used by falco (engine and outputs).
There's also a couple of minor cleanups:
- falco_formats had a private instance variable that was unused, remove
it.
- rename the package for the falco_formats functions to formats instead
of falco so it's more standalone.
- don't throw a c++ exception in falco_formats::formatter. Instead
generate a lua error, which is handled more cleanly.
- free_formatter doesn't return any values, so set the return value of
the function to 0.
