- backported from master
- fix for issue-17429 - DRC unnconnected items exclusion instability
- new serialization format for unconnected items (MainID and AuxID
last)

- ResolveDRCExclusions now matches unconnected items by not matching on
MainID and AuxID
Each knockout can be approximated, and each knockout
will have m_ExtraClearance added. If a neck is
between two knockouts, it will be 2X the above
values narrower than expected.

The arc center is a pseudo coordinate which is calculated for drawing
purposes. This mid point is fixed unless the arc is modified which
should result in more reliable arc parity footprint library DRC testing.
Also change EDA_SHAPE::Compare() to use the arc mid point.

When building a net tie, all elements in the footprint that belong to
the net tie can be arbitrarily close to one another. outside of the
footprint, connected items can be arbitrarily close to the tie element
but must respect the clearance values for elements that have nets
assigned to them

This is not only a useful place to hang regression tests,
but also allows to catch defects specific to loading or
saving footprints.
For example, it would catch:

- Remove bespoke collide routine. We should never rewrite these instead
of using the geometry library
- Optimize check by creating unified geometry before colliding
- Make extra variable that we don't need but makes cherry-picks easier

(cherry picked from commit a611c72c27e1000afb385cc230f1c288309e4c16)
Items that are part of net ties (pads and copper shapes that connect to
them) should allow connections from any net in the tie. This prevents
clearance errors from being generated for matched nets

If two nets are joined by a global power pin but both have global labels
that override the net name, we still want them to be merged. This
checks for all net names in the drivers when looking for subgraph
merging candidates

There was a motion towards fill solid/none around
2020 (c.f. b31e97cfeda9b76a165854b98974d253e221e93b),
but it was only for PCB_SHAPE.
Use yes/no universally (solid/none parsing the same way
as currently). In future if there are other fill modes
for these shapes, they can use the same pattern as ZONEs
do now: (fill yes) (hatch etc ....) or similar.

When zone kisses happen from different polygons, we need to be careful
not to use the different polygons for ear comparisons or prev/next
pointers

- Moves functionality to FOOTPRINT class from BOARD_ITEM
- Renames DRC property from ComponentClass to Component_Class
- Adds DRC checks QA for A.Component_Class and a.hasComponentClass('x')
CHANGED: PCB file format now supports saving/loading complex padstacks
CHANGED: PTH pads are now rendered per copper layer in the copper color;
the PTH pad color is no longer used.
ADDED: support for importing complex pad stacks from Altium PCBs
Enforce padstack-aware access to pad properties across KiCad
Fixes https://gitlab.com/kicad/code/kicad/-/issues/8182
- Adds Component Class field to SCH_DIRECTIVE_LABEL
- Adds SCH_SYMBOLs to SCH_RULE_AREA item lists
- SCH_SYMBOLs resolve Component Class directives
- Netlist exporter / importer handles Component Class names
- Adds DRC expressions and functions
- Adds QA check for component class netlist export
F_Cu = 0
B_Cu = 2
Remaining internal copper layers are even and incrementing
Non-copper layers are odd and incrementing.
This means that we can no longer do things like:
for( PCB_LAYER_ID layer = F_Cu; layer <= B_Cu; ++layer)
Instead, we have the class LAYER_RANGE:
for( PCB_LAYER_ID layer : LAYER_RANGE( F_Cu, B_Cu) )
Similarly, gt/lt tests should not refer to the integer value of the
layer. We have functions such as IsCopperLayer to test whether a layer
is copper or not.
When using the connectivity RTree, the third dimension is layer, so we
provide B_Cu with the special INT_MAX value, ensuring that elements
between F_Cu and B_Cu will be identified. There is a new, special
function GetBoardLayer() for interfacing with CN_ITEMS
Similarly, PNS layers remain unchanged and sequential. A set of
interface functions is provided to map PNS layers to Board layers and
back. This allows the PNS_LAYER_RANGE to function as expected
Enables DRC to calculate skew based on new arguments to skew
constraint DRC clauses:
Using (group_matched): calculate skew across all matching nets
Using (within_diff_pairs): calculate skew within every diff pair
found within the matching nets
Additionally fixes DRC skew calculation to calculate skew relative
to the longest net in the skew check set (in line with PNS meander
placer calculations).
Sometimes we don't get the data elements in order. Use the stream name
to ensure we have the correct model.
Also give the parser a bit more memory to work with, avoiding unneeded
resizes
Power symbols are implicit labels in KiCad, so we should check for their
caps difference against other power symbols as well as against other
labels
Fixes https://gitlab.com/kicad/code/kicad/-/issues/16897
Previously, fills could end up just barely touching, leading to DRC
errors even if there was enough room to fill the remaining space. This
was due to how we shrink/expand the zones to remove small features. By
adding a zero-width line between points that should be connected, we
expand back to the correct width.
Fixes https://gitlab.com/kicad/code/kicad/-/issues/14130
The previous commit merged pads with copper areas. This was appealing
but broke when the pad and the area were meant to have different
size/shape technical layers. Small pads = Small paste. Instead, we do
not merge the pads but we assign them to have the appropriate nets in
KiCad, allowing the same effective result but keeping the technical
layers correct
