When counting items, many cases exist where we want to count all items
without checking flags. This short-circuits the loop to provide the
immediate count.
- PNS_ITEMSET now keeps ownership info (does not rely on PNS_ITEM::Owner(), avoiding the risk of dangling pointers)
- fixed vias losing connected traces when dragging in mark obstacles mode
- fixed rare segfault when board item returned null netclass
- re-worked PNS_LINE_PLACER and PNS_ROUTER classes a bit, removing duplicate class members
- cleaned up Andrew's blind/buried via fixes
- fixed 'custom via width' dialog bug updating the width even when closed/cancelled
- fixed incorrect radius of drawn microvias
