There has been a long standing (since the beginning of the project?)
issue with sharing schematics between projects. It has been somewhat
supported for complex hierarchies (a sheet shared multiple times in a
single design) but it has not been well supported for simple hierarchies
(the symbol references cannot be changed in the shared schematic). This
issue has been resolved by moving all of the symbol instance sheet paths
from the symbol definitions in the all of the project files and save all
symbol path instances in the root sheet. This ensures that orphaned
symbol instance paths do not accumulate in shared schematic files and
that designs that reuse schematic in simple hierarchies can how have
different references. It also allows the root schematic from one project
to be uses as a sub-sheet in another project.
When legacy schematics are loaded, all sheet and symbol UUIDs are
converted from time stamps to true UUIDs. This is done to ensure there
are no sheet path instance clashes between projects. That being said,
there are no checks for this. It is assumed that the probability of
UUID clashes is so low that it doesn't make sense to test for them.
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.
We need to ensure that the appended sheet does not already exist in the
parent hierarchy. We do this for new sheets but need to check for
existing ones as well.

This moves EESchema DLIST structures to rtree. These changes are more
fundamental than the pcbnew changes from 9163ac543888c01d11d1877d7c1
and 961b22d60 as eeschema operations were more dependent on passing
drawing list references around with SCH_ITEM* objects.
"INPUT" declaration in sch_text.h generate *a lot of* compil warnings.
So it is replaced by PS_INPUT.
For consistency, others member of enum class PINSHEETLABEL_SHAPE are also renamed.
For legacy reasons, it stored left and right "spin" as flipped integers in the file format.
But the code handled the flip in multiple locations rather than just doing it on file io.
This change unifies the internal code and does the mapping in the file I/O.
Add missing check for root sheet when searching sheet hierarchies for
already loaded schematics. This prevents the root sheet from being
omitted when adding new sheets using the root sheet file name.
CHANGED: Make file name tests case sensitive so that schematic sheet
file names on non-Windows systems can be uses as expected.
Warn users when attempting to use schematic file names that only vary
by case sensitivity that doing so will result in a project that is not
portable to Windows.

The use of wxPATH_UNIX when calling GetFullPath() on windows drops the
volume identifier (c:\) from the file name which will cause comparison
failures.
Remove an existing sheet from the current page that requires a schematic
load from file to prevent a corrupt screen list from causing a segfault.
Merge the edit sheet file loading with the append schematic code since
they are functionally the same. This allows the sheet edit code to
take advantage of all of the added broken symbol library links added in
the recent append schematic fixes.

Don't edit sheet during AddToScreenAndUndoList() call. If it's
cancelled and we delete the item, callers will still own pointers
to the freed memory. Do it in New and Paste instead.
When importing an existing schematic into a sheet that was no remapped
to use the symbol library table, the user was given the option to ignore
the warning and proceed with the import. This would end up with all of
the imported symbol links being broke. In hindsight, this was a bad
idea so now the user cannot import schematics that have been remapped.

Previously, when creating a new instance of a sheet, the full set of references
was cleared.
Moreover, if this sheet has sub-sheets, the annotation was incorrectly handled
Now only (and all) new sheet path(s) created have a reference cleared, as expected.
(new sheet paths can be more than one, if the new instance of the sheet has sub-sheets)

For the path separator in full filename, the sheet filename from the dialog uses the Unix notation,
and the "old" sheet filename uses the default notation (it is the actual filename).
Therefore, on Windows, after closing the dialog, the filename was always seen as modified,
and the hierarchy was incorrectly modified (annotation cleared).
The messages on sheet duplication are changed to reflect the action
perceived by the user when accepting/rejecting the change.
Annotation is also reset for duplicating sheets where maintaining
existing annotation would conflict with existing sheets.
