Whiteboard
Implemented a simplified plugin interface and a helper library that takes care of the yajl parser callbacks. It converts the JSON arguments and puts them in the plugin's structure.
There are two filter chains (pre-event-queue = db context and post-event-queue = ca context) where filters and plugins can insert their filter functions.
A number of plugins have been implemented and tested:
ts - sets the timestamp to "now" (to avoid wrong timestamps for monitors on fields that do not cause record processing)
dbnd - deadband algorithm
arr - array subsets
(?)
