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.
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.
It served us (mostly) well for more than a decade. It helped KiCad grow
before the std:: came into decent shape or speed. It was a good little
list.
RIP DLIST 2008-2020
This change completely removes the LIB_ALIAS design pattern an replaces
it by allowing LIB_PART objects to inherit from other LIB_PART objects.
The initial implementation only allows for single inheritance and only
supports the mandatory fields in the derived part because that is all
that the current symbol library file format will support. Once the new
file format is implemented and saving to the old file format is deprecated,
more complex inheritance will be added. The LIB_ALIAS information saved
in the document files was move into the LIB_PART object. This change
impacts virtually every part of the schematic and symbol library editor
code so this commit message is woefully incomplete.
REMOVE: Removed the symbol aliases concept from the schematic and symbol
editors and the symbol viewer.
NEW: Replace the symbol alias concept with simple inheritance that allows
a library symbol to be derived from another library symbol.
Even though slash is a valid character in symbol names, it is a revision
separator, but is not the case with Eagle symbol names.

Nets assigned by power pins are weak, meaning they are valid
as long as there is nothing else attached to such pins. This patch
checks whether there are other wires or pins attached to a power pin
before placing a global net label.

* https://bugs.launchpad.net/kicad/+bug/1755191
Each named power input pin in Eagle creates an implicit connection to a
net with the name of the pin (e.g. GND, VCC). It is also done for the
units (gates in Eagle nomenclature) that have not been instantiated in
the schematics.
To emulate this behaviour in KiCad:
- Placed components are checked for power input pins, so they will have
global net labels attached to create the described implicit connections.
- As the components are placed, the remaining units of the symbol are
checked for power inputs to see if they need to be instantiated together
with global net labels.

* https://bugs.launchpad.net/kicad/+bug/1755191
Eagle support net labels that are naming wires not directly connected to
the labels. In KiCad it is not possible, therefore such detached net
labels need to be moved, so they touch the corresponding wire.
The initial algorithm did not take into account that a moved net label
might be placed on a wire crossing, effectively shorting two nets. This
commit improves the placement algorithm by avoiding the wire crossing
points when placing a label.

* https://bugs.launchpad.net/kicad/+bug/1748502
Local net labels are preceded with sheetpath (even for single sheet
schematics it is '/') causing net name conflicts between schematics and
layout. It can be easily avoided by using exclusively global net
labels, at the cost having uglier schematics.
The previous implementation relied only on the project name. When it is
set, the imported library was named '-eagle-import'. Now it tries
the project name and then the file name, using 'noname-eagle-import'
as fallback.
The library name is stored in the plugin to avoid changing the library
name after the project name has been set.
- Also makes the project and file import functions filetype dependent.
- The change from IO_MGR::KICAD to IO_MGR::KICAD_SEXP removes a conflict from a compile definition for KICAD when compiling kicad/import_project.cpp
