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.

Each pad group is allowed to short nets with other pads in its group.
Legacy footprints with the "net tie" keyword hack will get a single
group auto-created with all the footprint's pads in it.
DRC and the router now allow a track to collide with copper graphic items
while entering a net-tie pad as long as the closest point in the collision
is within the pad.
DRC (and the footprint checker) now check for copper items in the
footprint shorting pads which are not in the same pad group.

Removes a nanny setting that prevented the use of
blind/buried/micro-vias without a checkbox. If the designer does not
want microvias in their board, they simply do not place microvias.
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
Threaded DRC access will write to this string, re-allocating the memory
without any synchronization between threads using the string. Comment
adding this listed performance as a reason for using shared strings.
Measured performance does not seem noticeably different in either case,
even with high-error count boards. If there is a case where the
performance is limiting, we can replace these wxStrings with
std::wstring and utilize fmt

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.

The basic problem is that the DRC engine does length testing and skew
testing by collecting all the diff pair constituent parts and pairing them
itself. Since each part is collected on its own, we need to ignore the
'B' unit when evaluating any conditional expressions. However, doing this
in general means that when evaluating "OwnClearance()" we also ignore the
'B' unit and return the diff pair CLEARANCE_CONSTRAINT when we shouldn't.
This implements a more discerning test which know what the current requested
constraint is when evaluating expressions.

Also includes going from distance-based neighbor exclusion to angle-
based. (Distance doesn't work when very short segments are followed
by very long ones.)
