Handles cancellation in main fill loop. Allows loops to finish without
restarting new ones. Further enhancement might allow breaking threads
cleanly but this gets 90% of the cases

1) The highest priority zone that a via/pad collides with "owns" its
connectivity state. Once set, lower priority zones cannot change it --
and in fact, if they would have connected to it are forced not to.
2) The connectivity state goes with the zone fill state, and therefore
must be saved in the file.
3) Display of remove-unconnected's pads is no longer done in GetViewLOD()
(which isn't called for selected items), and is instead done in PCB_PAINTER.
This allows us to draw the full pad in outline mode when a via/pad is
selected which would otherwise only show the hole.
4) Note that in some cases this will still generate DRC errors -- in
particular when a via nearly collides with a higher priority zone it
won't get "owned" by that zone and may therefore have insufficient
clearance if said zone concludes it's unconnected and a subsequent
(lower priority) zone connects to it (causing it to now become flashed).

pad of a given number.
Also improves other DRC logic to tighten up the net-tie rules now that
we know which pads are allowed to short with which other pads.
Also removes the "Overlapping pads" DRC violation now that we know
whether or not overlapping pads in a net-tie footprint constitute a
short.

Don't wait until all zones are filled before tesselating fills.
Tesselation happens on a layer-by-layer basis, so once the zones' layers
are filled, we can tesselate them in parallel with the remaining fill
work
When multiple zones overlap each other, we need to synchronize the
filling. This should not wait for all zones to try to fill before
restarting. Instead, zones that cannot be filled because the depend on
another zone finishing are immediately re-inserted into the fill queue.
The outline collision is relatively cheap (especially after filtering
bbox collisions) so check if a zone REALLY depends on another zone
before making it wait. Waiting for zones can really increase the total
fill time
1) Move a bunch of std::map's to std::unordered_map to get constant-time
look-ups
2) Lengthen progress-reporting intervals to spend more time doing work
and less time talking about it
3) Reverse order of SHAPE_LINE_CHAINs in thermal intersection checks to
make (much) better use of bbox caches
4) Don't re-generate bboxes we already have
5) Fix some autos that weren't by reference (and were therefore copying
large datasets)
6) Rename delta progressDelta so it's easier to search for in future
7) Get rid of a few more autos (because I don't like them)
8) Pass large items to lambdas by reference

Thread pools are long-lasting executors that have close to zero overhead
when launching new jobs. This is advantageous over creating new threads
as we can use this for threading smalling jobs and smaller quanta. It
also avoids the heuristics needed to determine the optimal number of
threads to spawn
Removes some duplicated terms; puts in some more headers to make
visual parsing easier, and makes non-connected-pads report the correct
data.
Also fixes a bug where zone-connection overrides of none weren't getting
handled correctly.

1) Drop tiny islands which might cause connection problems.
2) Cleanup some dead code in filler
3) Don't estabilish a connection to an island that is fully covered
by whatever its connecting to.
