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.
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.
CHANGED: Settings are now stored in versioned sub-directories

CHANGED: Settings are now stored as JSON files instead of wxConfig-style INI files
CHANGED: Color settings are now all stored in a separate settings file
CHANGED: The symbol editor and footprint editor now have their own settings files
CHANGED: Color settings are no longer exposed through BOARD object
CHANGED: Page layout editor now uses Eeschema's color scheme
Settings are now managed through a central SETTINGS_MANAGER held by PGM_BASE.
Existing settings will be migrated from the wxConfig format on first run of each application.
Per-application settings are now stored in one class for each application.
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.
Use the root symbol when comparing against the cached symbol when
checking to see if a symbol changed. When the original symbol is
a derived symbol, the test will always fail.
Force a symbol link refresh on a rescue to prevent stale links from

on demand.
Force a symbol link refresh on project load to prevent stale links from
symbol link changes from crashing the connection graph when the project
rescue in invoked.

The new connectivity algorithm had a tendency to cleanup
globally, but that could insert undo records from other sheets
into the current screen's undo stack. Needless to say, this
was a recipie for segfaults.

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

the recent append schematic fixes.

This fixes the last suffix that was missed by 168fa09f5. The schematic
backup files should have the suffix .sch-bak to distinguish from
.kicad_pcb-bak or other backups.
(cherry picked from commit b6fe4ff637)
Do not add cache library from another project to old library list. This
is wrong and can cause all kinds of symbol library linking issues. It's
better to force the user to fix broken symbol library links than the false
security of using multiple cache libraries.
Use correct paths when appending schematic outside of the current project
path when hierarchical sheets are appended. If the path can be relative,
give the user the option to use either relative or absolute paths.
Do not change symbol library names in schematics appended from a source
outside the current project. This will almost ensure the symbol library
links will be broken in the source project.
When the appended schematic is from another project, attempt to check all
of the possible combinations of symbol library table importing that could
cause broken symbol library links and give the user the option of canceling
the append operation or live with the possibility that there may be broken
symbol library links.
When the append schematic is in the current project path but not part of
the schematic, check to see if there are any library nicknames that do
no exist in the project symbol library table and give the user a chance
to cancel the append process.
EEschema optimizes wires by merging colinear segments. If a schematic opened without a valid
cache library or missing installed libraries and later saved, this optimization can cause connectivity
errors. In order to fix that we check each pin-wire connection and junctions if necessary.
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.
After importing Eagle files, we need to make sure that the connectivity
network is updated before the system requests a new netlist. Otherwise,

Autosave was not working correctly, partly due to different
implementations in eeschema and pcbnew and partly due to a mistaken
refactor at some point during v5 development. This unifies the expected
autosave prefix to _autosave- for both pcbnew and eeschema. It also
unifies the expected suffix for the backup files to -bak.

Do not keep pointer to SCH_EDIT_FRAME in the rescuer object to prevent
it from creating dialogs with itself as the parent when call from the
rescue dialog which is itself a grandchild of the frame window.
Eagle can label nets independently of the connection point position. In
an "interestingly" designed circuit, this can lead to a junction of a
pin, wire endpoint and unrelated wire. While this is bad practice,
KiCad shouldn't force an incorrect net connection during the import. In
this case, we skip the addition of junctions to ensure that we don't
create a schematic error.

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.
