Always print events
...
Before this change, events were only printed if they had all the
fields (same behavior as with sysdig when the output format doesn't have
a leading "*"). With this change, all events are printed; those that
don't have all fields are prefixed with a notification.

Add 'sysdig.set_formatter' and use it in compiler

This allows the compiler to define per-rule formats. They are currently
instantiated and stored on the c++ side, but not being made use of yet.

Move compiler state and AST grafting to rule_loader.lua

This is needed so that rule_loader (which should be renamed in a later pass..) can tag
filters with their index.

Lua parser refactoring
...
Move compiler loading out of libsinsp/lua_parser.cpp and into a new
class in digwatch/rules.cpp.
This way the libsinsp support is strictly about providing a lua API for
scripts to setup filters. Loading the actual parser and rules is logic
that belongs in the app (digwatch in this case, maybe sysdig down the
line) rather than there.
