Jon Evans 1e33928b96 Fix issues with zone filling connectivity locking
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.

jean-pierre charras 067b94c410 DRC: Fix a incorrect message and marker position when testing dangling vias.
Commit 6ffb721 detects vias connected on only one layer.
But the DRC diag (marker position and error message) were not correctly initialized
for this new test.

Seth Hillbrand 6ffb72159a Remove vias if they only connect to single layer
A via takes up zone space on additional layers, so if we are not
connecting to those layers, then we should remove it.

Wayne Stambaugh ede39780e2 Remove all debugging output that cannot be disabled.
The use of printf, wxLogDebug, and std::err/std::out causes excessive
debugging output which makes finding specific debugging messages more
difficult than it needs to be.

There is still some debugging output in test code that really needs to
be moved into a unit test.

Add debugging output section to the coding policy regarding debugging
output.

Seth Hillbrand b8b3d5c16d pcbnew: Remove all threading from dynamic ratsnest
The last remaining threaded operation in dynamic ratsnest was the
recalculation of the dynamic connectivity map.  Because we do not
require any of the extra features of the connectivity map, we can get
away with a lightweight move of the anchors to update the ratsnest.  The
resulting connectivity tree is not valid but it is not needed for the
ratsnest, which only needs a list of nets/anchors.
