Setting stub width to a ridiculous large value (for instance 100 times the pad size) creates strange and broken shapes,
and obviously stubs cannot be built.
Ensure also the thermal shape is inside the zone boundary (because the algo adds areas this was previously possible)

This unifies the zone refill across architecture into the tool-based
architecture. Also provides ZONE_FILLER-based progress managment for
tools.
(cherry picked from commit be9cd98cb1)
It's too complicated trying to keep everything smaller or larger by
half the pen width, and some things like spoke-end-detection need the
actual outline anyway.
The thermal spokes are anchored at the pad anchor. They may or may
not make sense, depending on the pad shape. It's up to the author
to move the anchor around as necessary or to not use thermals.
This places the arc approximation setting in the kicad_pcb file and uses
it for all parts of the board rendering where arcs are converted to
segments. This allows the user to customize their speed vs. accuracy
tradeoff. The default setting of maximum error of 0.005mm is acceptable
for small boards on moderate systems.
This removes the remaining hard-coded segments counts and replaces them
with the relative error calculation where the segments per arc is
determined by the maximum error we allow (smaller arcs = fewer segments)
1 - For debug purposes, the code to fill non copper zones was disabled and the copper zone code was uses instead.
It creates issues with pad clearance areas, because a non copper zone has no clearance areas.
2 - The non copper zone dialog had no option to set the outline smoothing option.
Unfortunately, this parameter was inherited from the last edited copper zone.
And therefore the non copper zone can have a non wanted outline smoothing option.
This option is now added to the dialog.

Give the user the option of cancelling a file open if there are
segment zones; otherwise they're converted to polygon fills.

For legacy boards, the setting is picked up from the board outline
thickness. If the board outline has mixed thicknesses, then the
max is used and a warning is displayed.

the filled areas can use a hatch pattern (crossing lines) using square holes.
The zone filler removes too small holes (truncated holes) from hatch pattern.
It avoid to create small holes when a hole pattern is truncated by the filled area base shape.
Commit 6006703798 fixed a crash but broke the filled zones changes detection.
Filled zones were always seen as not up to date due to the fact the filled areas were cleared too early.
The up to date detection is also optimized: the old filled polygons are no longer stored.
Instead of, the MD5_HASH is calculated and stored before clearing the filled polygons.
Previously, in many cases the selected zone was refilled on exit selection, even if the zone was not modified.
This is annoying, because the zone fill can be really time consuming, and cannot be called without a good reason.
Now the refilling is made only if a zone parameter is actually modified.
Removing existing fills will prevent re-drawing invalid polygons before
they are ready. This seems to happen on Macs more easily due to redraw
timing.

This was due to the stub removal tests if a stub end is outside a solid area to remove it.
There is a corner case: is the stub end is exactly on a solid area outline extra segment
created by Fracture() used in calculations.
The stub removal tests are now made before fracturing.

No net zones, by definition, do not connect to any other element.
Therefore, the entire net is an island and should not be removed by the
knockout section

Non-connected zones are, by definition, not connected, therefore, we
should not knock out thermal reliefs under any case

Where we can get away with lower segment counts (localizing an anchor),
we keep the low-def 16 segment count. Intermediate values and values
that are visible to the user are set to high definition. Most are
simply hints to the inflation correction but where they show, the user
show see smooth lines.
Most rounding operations have been shifted to an absolute error
calculation and the ability to adjust zone segment counts has been
removed in 5.1. The remaining elements that use fixed segment counts
are either 18 (DRC) or 32 (plotting). This aligns the punchout segment
count with the higher (32) definition value
Rather than depend on proper unlocking for each exit, we move the
connectivity lock mutex into an RAII-type configuration that
automatically unlocks on exit.
