Each pad group is allowed to short nets with other pads in its group.
Legacy footprints with the "net tie" keyword hack will get a single
group auto-created with all the footprint's pads in it.
DRC and the router now allow a track to collide with copper graphic items
while entering a net-tie pad as long as the closest point in the collision
is within the pad.
DRC (and the footprint checker) now check for copper items in the
footprint shorting pads which are not in the same pad group.

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.

(cherry picked from commit 2a91ba35c1)
The shove algorithm can't move the loose track ends. It always needs a via. In case of wide segments stitched with
a small via, the collision search finds only colliding segments and does not consider the via. This leads to frequent shove falilures
or 'choppy' behaviour when the head line only slightly overlaps with an end of a thick trace. This patch attempts at improving this behaviour
by considering the 'tiny via in wide segment' case explicitly.
Also checks the nets when checking for a pad being flashed on a particular
layer (so we don't end up thinking the currently-routing-collided track
is a connection).
Minimum differential pair clearance should be limited to the netclass
differential pair spacing. This also cleans up some unused code that
was left over from previous work on differential pair clearances.

add overloads for NODE::Add( ... ) taking pointers to specific item types (retain old private add-Functions, they will come in handy later)
LINE overloads now take by reference, to document their special treatment.
