sounds reasonable to drop unneeded macro computation when we actiually know about these things already on logging.

core logging: Get rid of the insane macro usage
Computing macros is ridiculously expensive. Looking them up is
even more so. While fixing the macro lookup thing would be a
Good Thing(tm), using macros for this simple purpose is very
much overkill. This patch remedies that particular folly and
reduces load-time by an immense amount in large networks when
initial states logging is enabled.

core: get rid of the instame macro usage while logging alerts and states (Andreas Ericsson) #2665

previously, each alert or state being logged caused all host and service
macros being grabbed (including memory allocation for those), and
logging the final processed buffer. as we can use some smaller switch
case function helpers to generated the same output for the already known
attributes on those hosts and services, we just remove that insame cpu
burning 'feature'.
