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.

ADDED zone_connection constraint.
ADDED thermal_relief_gap and thermal_spoke_width constraints.
ADDED angle override for thermal relief spokes in Pad Properties.

Push the mutex down into the ZONE::Fill() routine and set the
connectivity update to run after zone fills. The connectivity update
cannot run while the mutex is locked for zone fills.

- Some are related to shape errors when the allowed error to approximate circle
by segment is large and arc radius small.
- fix the actual error used in ConvertToPolyline().
- Use SHAPE_ARC::DefaultAccuracyForPCB() instead of a fixed value as extra margin
in zones. It should not change something, because it is also a fixed value
(5 micrometers), but it is not a magic number.
-TransformArcToPolygon() fix some issues and add a new algo, based on the arc actual
outline shape (initial algo is still available in code, just in case).
The nettie hack is used in DRC but we also need to use it in zone filler
to allow zones to be used with netties. We limit this to the
appropriate nets in the nettie

Zone connections (even half-connections) should trigger the connected
logic in flashPads. This removes the double-standard for painting pads
and imposes thermal standoff based on the net connection to the pad if
it shares a net, not just if connected
Two issues found with the locking system used to prevent access to
stale connectivity data during the zone fill process:
1) a std::mutex has undefined behavior if you try to use it to guard
against access from the same thread. Because of the use of wx event
loops (and coroutines) it is entirely possible, and in some situations
inevitable, that the same thread will try to redraw the ratsnest in the
middle of zone refilling.
2) The mutex was only guarding the ZONE_FILLER::Fill method, but the callers
of that method also do connectivity updates as part of the COMMIT::Push.
Redrawing the ratsnest after the Fill but before the Push will result in
stale connectivity pointers to zone filled areas.
Fixed (1) by switching to a trivial spinlock implementation. Spinlocks would
generally not be desirable if the contention for the connectivity data crossed
thread boundaries, but at the moment I believe it's guaranteed that the reads
and writes to connectivity that are guarded by this lock happen from the main
UI thread. The writes are also quite rare compared to reads, and reads are
generally fast, so I'm not really worried about the UI thread spinning for any
real amount of time.
Fixed (2) by moving the locking location up to the call sites of
ZONE_FILLER::Fill.
This issue was quite difficult to reproduce, but I found a fairly reliable way:
It only happens (for me) on Windows, MSYS2 build, with wxWidgets 3.0
It also only happens if I restrict PcbNew to use 2 CPU cores.
With those conditions, I can reproduce the issue described in #6471 by
repeatedly editing a zone properties and changing its net. The crash is
especially easy to trigger if you press some keys (such as 'e' for edit)
while the progress dialog is displayed. It's easiest to do this in a debug
build as the slower KiCad is running, the bigger the window is to trigger this
bug.

Also a rationalization of text polygon generators, with the "standard"
version inherited from BOARD_ITEM now giving the bounding box. This
requires callers who want the (much) more expensive stroke-based one
to call it explicitly (and brings PCB_TEXT in line with the was FP_TEXT
already was.
