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
Now that we are dealing with individual connection elements that do not
update their connected elements as well, we can thread the update, just
being careful to guard any remaining updates (bus_enty/busLine) that
need reciprocal updating

If the SCH_ITEM has already been processed, the extra time needed to
iterated over the memberset and get the SCH_CONNECTION when we won't use
it is not neccesary.

Normally, you will gain by resursing a nested loop only over the
pairs that are not already handled. In this case, however, you lose
time because you step outside of the cache by adding the reciprocal test
at each step.
Instead, we process one element at a time, keeping it cached and loop
over all other elements to add to the connection. This saves us about
75% of the time for larger loops (e.g. stacked power pins on a large
BGA)

We want to shorting the processing time by marking symbols that have
already been processed. But we must avoid marking symbols that will not
be processed due to their other flags

(cherry picked from commit 2208e0db16)
Needed to find bottlenecks in fns, so break out individual sections of
the massive function for easier understanding.
buildItemSubgraphs (one section of the previous function) would build
millions of connections that were never used as stacked pins created X!
connections. Also tested using sets instead of lists and keeping unique
lists to avoid flagging but none of these were as performant as using
flags to remember which items had already been processed.

They don't define a KiCad string class, so the header file name was
somewhat misleading. But the fact that they didn't match definitely
made coding more difficult.
Certain situations can trigger the stale cleanup being run
on a bus that doesn't actually contain the stated member.
In this case we should just keep calm and carry on -- who knows
what netlist will be generated, but we shouldn't crash.
Fixes https://gitlab.com/kicad/code/kicad/-/issues/8530
ADDED a new pin electrical type "free" for internally unconnected pins.
CHANGED the "unconnected" pin electrical type is now represented by
"no_connect" in files and netlists. (The legacy syntax is also accepted
in files.)
This way the net names can be inspected in eeschema and cross-probing works.
Testcases updated for the name changes
CHANGED: all unconnected pins are now included in the netlist with no_connect_ prefixes
