Avoid O(N^2) by spatial sorting, don't run checks if the bounding boxes
don't overlap.
A second copy is ordered by type to help classes that only want to check
a few types having to walk the whole list.
We store our connectivity dirty flag with the SCH_ITEM but we generate
SCH_CONNECTION based on the SCH_ITEM and the SCH_SHEET_PATH. For this
reason, we need to avoid clearing the connectivity dirty flag until
we've finished processing all instances of the SCH_ITEM in the graph
This also means that we need to allow getting the SCH_CONNECTION pointer
even when the connectivity is still dirty (getting SCH_CONNECTION
happens based on SCH_ITEM and SCH_SHEET_PATH, not just SCH_ITEM)
While it's a bit of an encapsulation leak (see comment in
CONNECTION_SUBGRAPH::driverName()), it more than doubles undo/redo
performance in documents with *lots* of nets.
This is required to keep selected and brightened state across undo.
It's also probably required for things like IS_SHOWN_AS_BITMAP and
possibly ENTERED. FWIW, most BOARD_ITEMs do a straight swap, including
the temp and edit flags. But that seems like a risky change....
Also removes SyncView() call from Undo/Redo as that does a MODEL_RELOAD
which clears the selection.
Previously, almost all connectivity updates were full updates, meaning
that the entire connectivity graph would be rebuilt each time a change
was made to the schematic. This update modifies the update to only
correct the subgraphs that are directly affected by the change.
It uses the existing connection graph to find all affected subgraphs as
well as connections to the changes based on the visible schematic.
These elements are removed from the existing connectivity graph and
marked dirty. They then have a new connectivity graph built only around
their changes. The resulting graph is merged into the original.
Currently, this ability is behind an advanced config flag
`IncrementalConnectivity` while testing.

Also moves most navigation code to SCH_NAVIGATION_TOOL.
Also changes page number href to anchor syntax ('#foo').
Also adds hypertext processing to SCH_TEXTBOXes.
Also adds combobox with schematic pages to text properties dialog.
Also adjusts metrics to better match stroke font.
Also removes text-halo highlighting as it's too expensive to re-render
when the zoom changes.

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.
Fixes https://gitlab.com/kicad/code/kicad/issues/10974
(cherry picked from commit 17b1b68ac7)
1) Generalize SCH_ITEM owners (SCH_COMPONENT, SCH_SHEET, and now
SCH_GLOBALLABEL)
2) Generalize hypertext items
3) Use SCH_FIELD autoplace infrastructure for placing intersheet
references
4) Use textVar infrastructure for buildin intersheet references.
As an important side-effect this also fixes the undo issues with
intersheet refs.
ADDED Eeschema-specific netclass settings including wire and bus
thickness, color, and line style.
Netclasses override individual wire & bus colors and line styles.
If that proves an issue we might look at something more sophisticated
with inheritance.

Remove extraneous use of FLAG0 from tracks cleaner (it was checked but
never set).
Fix issue in expand connections where two parts of it couldn't agree
on the same flag (BUSY vs SKIP_STRUCT), and where the second part was
clearing the flag instead of setting it.
Remove obsolete HIGHLIGHT infrastructure (we now use selection).
Remove extraneous use of BUSY flag in several places (it was never
set).
Set up a new lineage for SCH_ITEMS to get back to the SCHEMATIC
they live on: Items will all be parented to the SCH_SCREEN that
they are added to, and each SCH_SCREEN will point back to the
SCHEMATIC that it is part of. Note that this hierarchy is not
the same as the actual schematic hierarchy, which continues to
be managed through SCH_SHEETs and SCH_SHEET_PATHS.
