currently, services are only checked against their link to the host, but the host object itsself is not updated on the number of linked hosts - that happens later on the preflight check itsself.

while the number is also an indicator for the warning "host has no services associated", the more interesting part is the flapping detection where the total service check interval needs to be taken into account as well somehow.

in order to solve the inefficient pre flight "loop again over all services and check the host relation and update values" we'll do that directly within the link check and only check the numbers later on.

inspired by https://github.com/dnsmichi/nagios-svn/commit/1aca8a358a001e1940ad6cc6be0a695d94340c6b but fixed for flapping.

core: increase performance on host->service relation counter (config reading, flapping)

when a service is checked against its host association we can already
update the relation counter as well as total check interval.

the first is required for the config pre flight check while the second
is used within flapping detection.

original patch by Andreas Ericsson, fixed for usage in Icinga.
