f710edcde2 wip(userspace): checking module using event timestamps rather than an external timer 
This approach does not sound good to me since events can miss
timestamps.

Furthermore logically it is wrong to check the module sends event using
the events ...

94d89eaea2 New tests for handling multi-doc files 
New automated tests for testing parsing of multiple-doc rules files:

 - invalid_{overwrite,append}_{macro,rule}_multiple_docs are just like
   the previous versions, but with the multiple files combined into a
   single multi-document file.

 - multiple_docs combines the rules file from multiple_rules

The expect the same results and output as the multiple-file versions.

76f64f5d79 Properly parse multi-document yaml files 
Properly parse multi-document yaml files e.g. blocks separated by
---. This is easily handled by lyaml itself--you just need to pass the
option all = true to yaml.load, and each document will be provided as a table.

This does break the table iteration a bit, so some more refactoring:

 - Create a load_state table that holds context like the current
 - document index, the required_engine_version, etc.
 - Pull out the parts that parse a single document to load_rules_doc(),
   which is given the table for a single document + load_state.
 - Simplify get_orig_yaml_obj to just provide a single row index and
 - return all rows from that point to the next blank line or line
   starting with '-'
