(We don't control the order of the TransferDataFromWindow calls
for the various panels and here the junction dot size is dependant
on the default netclass wire size. So that calc has to be done
after all the various TransferDataFromWindow calls are made.)
Fixes https://gitlab.com/kicad/code/kicad/issues/9541
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.
CHANGED: In Schematic Setup->General->Formatting->Connections, added
pulldown for "Junction dot size" with values none, smallest, small
default, large, largest" Added support in "sch_painter.cpp" to not
paint junction when they have a diameter of "1" which is what "none"
sets as the diameter.
CHANGED: Remove wire and bus formatting GUI elements from "Schematic
Setup" dialog panel. Wire thickness is handled by netclasses now
and this was a leftover from before that change.

Also fixes a bug where a bunch of eeschema settings weren't getting
loaded because it looked like they were larger than the max value
(which wasn't being scaled from mils to internal units).
