[geometry] Added RobustPolicy to copy_segments and append_no_dups_or_spikes
- and moved typedefs inside function two times
- no other actions
[geometry] Simplified copy_segments template signature,
now that we also added RobustPolicy
[geometry] Added testcase for mailing list report 2014/02/23
[geometry] Use robust_policy in append_no_dups_or_spikes
Only if robust_policy would make any difference, so we added an "enabled"
boolean into the policy
