This is a very large and potentially disruptive change so this will be an
unusually long and detailed commit message.
The new file formats are now the default in both the schematic and symbol
library editors. Existing symbol libraries will be saved in their current
format until new features are added to library symbols. Once this happens,
both the legacy schematic and symbol file formats will be no longer be
savable and existing libraries will have to be converted. Saving to the
legacy file formats is still available for round robin testing and should
not be used for normal editing.
When loading the legacy schematic file, it is imperative that the schematic
library symbols are rescued and/or remapped to valid library identifiers.
Otherwise, there will be no way to link to the original library symbol and
the user will be required manually set the library identifier. The cached
symbol will be saved in the schematic file so the last library symbol in
the cache will still be used but there will be no way to update it from the
original library.
The next save after loading a legacy schematic file will be converted to
the s-expression file format. Schematics with hierarchical sheets will
automatically have all sheet file name extensions changed to .kicad_sym
and saved to the new format as well.
Appending schematics requires that the schematic to append has already been
converted to the new file format. This is required to ensure that library
symbols are guaranteed to be valid for the appended schematic.
The schematic symbol library symbol link resolution has been moved out of
the SCH_COMPONENT object and move into the SCH_SCREEN object that owns the
symbol. This was done to ensure that there is a single place where the
library symbol links get resolved rather than the dozen or so different
code paths that previously existed. It also removes the necessity of the
SCH_COMPONENT object of requiring any knowledge of the symbol library table
and/or the cache library.
When opening an s-expression schematic, the legacy cache library is not
loaded so any library symbols not rescued cannot be loaded. Broken library
symbol links will have to be manually resolved by adding the cache library
to the symbol library table and changing the links in the schematic symbol.
Now that the library symbols are embedded in the schematic file, the
SCH_SCREEN object maintains the list of library symbols for the schematic
automatically. No external manipulation of this library cache should ever
occur.
ADDED: S-expression schematic and symbol library file formats.
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.
There is no need to create a new root symbol and re-parent all derived
symbols when renaming a root symbol. Just rename the buffered root
symbol.
Test for duplicate symbol names when validating the properties dialog
information to prevent broken symbol pointers.
Fix a field drawing bug when editing derived symbols.
Fix bug to insure duplicate symbol names cannot exist in a library.

Fixes kicad/code/kicad#3672
The library manager update part function was orphaning the root symbol
of derived symbols when the root symbol was edited. Re-parent the
inherited symbols when updating a root symbol.
Update the mandatory field attributes whenever the parent is set for
derived parts. This will show the fields with the correct attributes
in the symbol editor and viewer.
Using std::unique_ptr to hold the current symbols was deleting the
pointer on symbol selection changes causing the pointer in the library
manager buffer to be stale in some cases. Revert back to using a
simple pointer and manual clean up as required.
Prevent derived symbols from being saved to a different library to
prevent orphaned symbols.
Fixes kicad/code/kicad#3649
The symbol editor selection criteria did not include LIB_FIELD objects
which allowed the root symbol name to be changed causing broken derived
symbol links. Disable the symbols fields from being edited when a
derived part is shown in the editor to prevent this.
Add a missing warning that deleting a root symbol used to derive other
symbols would also delete all derived symbols from a library. Give the
user a chance to cancel the delete operation in this case.

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.
1) don't ASSERT; use exceptions (which can be caught) instead.
2) clean up LIB_LOGGER so it's only used during sync
3) fix typos in wxLogMessage() calls so they produce output.
4) throw on unrecognized token in loadContent().
5) if clipboard can't be pasted as content then paste as text.

Also changes the presentation of the string when the checkbox appears
so that the "Changes will be lost" warning isn't hidden by the turndown.
This last part may require conditional compilation as it's undocumented.
Lastly, regularizes the Unsaved Changes strings between the apps.
A bug in LIB_MANAGER::LibraryExists() prevented a library removed from
the symbol library table from being removed from the tree view. Add the
proper check to SYMBOL_TREE_SYNCHRONIZING_ADAPTER::Sync().
This exposed another issue with synchronization between the library
table editor and the tree view which could lead to orphaned library
modifications and/or a segfault when the currently selected library was
removed from the symbol library table. Give the user a chance to save
or revert any changes before allowing changes to the symbol library
table.

When loading a part in libedit, also transfer certain screen
settings to the incoming SCH_SCREEN, from the current
SCH_SCREEN.
Currently, the grid settings are transferred, but this could
also do other settings if needed.
Also remove some duplicate commentary and mention why the
grid is set in a SCH_SCREEN even though the BASE_SCREEN ctor
sets the same default.
