rework digwatch event output handling
...
the high-level change is that events matching a rule are now send into a
lua "on_event" function for handling, rather than doing the handling
down in c++.
more specifics:
before, the lua "load_rule" function registered formatters with
associated IDs with the c++ side, which later used this state to
reconcile events with formats and print output accordingly.
now, no such state is kept on the c++ side. the lua "load_rule" function
maintains the id->formatters map, and uses it to print outputs when it
receives events.
this change simplifies the existing flow and will also make the forthcoming
implementation of function outputs far simpler than it would have been
in the current setup.

Grammar: support function-call syntax in outputs
...
This change adds syntax support for function call outputs. For example:
... | syslog(evt, WARN)
Regular outputs are still allowed and parsed in the same way.

Grammar: fix commas in lists

commas were (unintentionally) optional in lists. so a list like (a b c)
