Tomasz Wlostowski e558893851 router: use actual snap point position for routability checks of a segment instead of the segment endpoint(s). 
Explanation:
- place a long segment A with something violating the rules close to its endpoint
- try to start routing in the 2/3 of the length of A (on the obstacle side)
- bummer - the router picks the nearest endpoint of A for the collision check (even though we don't care about this collision since we want to route far away from it)

Jon Evans 9a2950cca1 PNS: Use exact hulls for walkaround path generation 
When we generate hulls, by default we subtract the clearance epsilon
to prevent false collisions in the router that wouldn't be flagged
by DRC.  However, we need to use the actual hull with no epsilon
when generating hulls for pathfinding in the walkaround system.

Without this change, it is possible for the walkaround to generate
a valid-seeming path that results in a DRC violation, for example
when dragging a drag against a board edge.

Jon Evans cf53b053a1 Improve handling of dragging around locked segments 
Locked segments now are not modified if they weren't the start item.
If a locked segment is the start item, it is automatically unlocked.

Roberto Fernandez Bautista aa67abb681 PNS::NODE Use PointCount instead of calculating segment index manually 
There is no need to manually calculate the segment index - we know
that the last point that was added is the start point of the segment.

Roberto Fernandez Bautista c3051ba48a Refactor SHAPE_LINE_CHAIN to allow two shapes per point 
m_shapes now has two possible indices. The first one is populated if
the point is associated with an arc and the second index is populated
if the point is shared between two arcs.

Marek Roszko cf2bb5692a Remove the wxLog calls from math/util.h for now 
This was leaking windows headers and partial wx headers to 1084 compilation units......
This also means math/util.h is leaking to 1084 compilation units which seems a bit high too.

Tomasz Wlostowski ebd957b08e router: rework router's debugging infrastructure to be more compatibile with the 'qa/pns/pns-log-viewer' tool. 
The log viewer tool lets you inspect all the intermediate stages of the routing algorithms. This patch:
- Adds source location tracking of the debug calls (need to use the PNS_DBG macro, sorry)
- Moves some wxLogTrace calls to DEBUG_DECORATOR::Message() so that messages can be displayed alongside the corresponding geometric shapes

Jeff Young 8b849b1c49 Fix several bugs in hull push-back with vias. 
1) take hole plating thickness into account
2) build hulls specifically for via so pushing back to the hull doesn't
have to try and figure out how much extra to push back for the via
and/or hole
3) clear MK_HOLE flags when colliding with the pad itself so that we
don't get stuck in HOLE mode
4) move flag setting/clearing to updateNearest() so that it will keep
track of the state of the nearest collision
