From master branch, commit #bfe59581

Due to some bug in Fillet() incorrect zone outline happens in (rare) polygon shapes.
So clip it with the initial polygon (aSmoothedPoly must be contained in m_Poly)
Fixes #9692
#9692

In line with
https://dev.opencascade.org/doc/overview/html/occt__upgrade.html#upgrade_occt760_poly
the Poly_Triangulation does not provide direct access to the internal
arrays anymore - use the accessor functions instead.
To keep changes minimal, switch only builds with a new (7.6+)
OpenCascade to the new API and keep everything else the same.

The overload of wxFilePath::FindValidPath() broke the normal behavior
when the file searched for existed in the current working directory.
This was causing the initial library table file to be copied from the
current working directory instead of from the list of search paths.

When the layers are adjacent, the microvia is _probably_ valid.  This is
not the case when trying to run a microvia through the core material but
without stackup information, we cannot be certain.

Note that microvias are not required in current manufacturing techniques
to be blind.

The kicad-pcb.org website is no longer valid

kicad-pcb.org seems to cause TLS handshake errors recently.
As kicad.org is now the official domain, switch all uses of
kicad-pcb.org to kicad.org in kicad.appdata.xml.in.

Now that ngspice creates soversion'ed libraries, we need to tweak
how we copy the dylibs around.

This is meant to address
#9143.

(cherry picked from commit ec10b12c)

Root out a few other areas where the hierarchy integrity test was being
performed while editing where it wasn't required.

The delay was due to recursion checks being performed every time a new
SCH_SHEET_LIST object was created.  The fix was to back port the optional
integrity check flag added from master.  It's similar to commit 63a0f537
by Jeff Young but it could not be cherry-picked due to the changes in
master branch.

Fixes #9278

Mostly from c6bcb855 but trees have
diverged sufficiently that there are others mixed in.  This removes the
system() call on MacOS when opening a directory

See master branch, commits 0cf81b6d and b065ff33

See master, commit 5abe25

From master branch, commit b1c67d9a

We require API compatibility in the ngspice library because we
dynamically load the library and assign function pointers to specific
names/signatures.  This should be consistent for all versions of the the
library until the soversion changes.

In this case, the default is INCH,LZ that looks like the more usual.
