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.
Add missing plot and print changes for the new bus entry properties.
ADDED: Junction properties diameter and color can now be edited.
Fixes: https://gitlab.com/kicad/code/kicad/issues/4593
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.
Please note that the symbol cache is not embedded in the schematic file
to allow for round robin testing with the existing file format. Once
the parser round robin testing is complete, the symbol cache will be
embedded in the schematic file.
This implements all existing symbol library object support and the ability
to save and load symbol library files between file formats for round robin
testing.
CHANGES: Symbol library file format has been converted to s-expressions.
Add support code for picking apart symbols at some future junction that
will allow full inheritance conversion of existing symbol libraries. For
now, symbols arranged by unit and body style numbers are nested for round
robin testing of symbol libraries once the parser is complete.
CHANGED: Settings are now stored in versioned sub-directories
ADDED: First-run dialog for migrating settings from a previous version
CHANGED: Settings are now stored as JSON files instead of wxConfig-style INI files

ADDED: Back annotation algorithm,
eeschema back annotation dialog
CHANGED: added some minor helper methods to SCH_REFERENCE_LIST and SCH_REFERENCE,
split SCH_REFERENCE_LIST::CheckAnnotation on 2 parts to reuse code
