This fixes all of the warnings cause by using std::weak_ptr objects when
recursing the symbol inheritance tree to retrieve the root symbol. The
issue is that the weak pointers are not guaranteed to be valid for each
recursion because the lock will go out of scope. Using a std::shared_ptr
object will ensure the lock is valid until it goes out of scope.
This fix makes some fundamental changes to the way symbols are rescued:
* The new symbol library file format is used when rescuing symbols defined
in the symbol library table.
* The original library nickname is appended to the symbol name rather than
the rescue library nickname when rescuing symbol defined in the symbol
library table.
* Escaping strings has been removed from legacy library rescues since the
legacy library file format never supported it.

When a rescue library already existed, the disabled writing of legacy
symbol library table entries prevented the rescue library from being
updated.

The legacy symbol library plugin code was changed to escape symbol names
which broke the LIB_ID string comparison when checking to see if symbols
needed to be rescued. Escaping the LIB_ID names before comparison resolves
the issue.

Apparently at some point during V5 development, symbol cache library names
were saved by replacing the LIB_ID separator character ':' with '_'. This
caused the cache look up to fail there by skipping the symbol rescue which
could result in broken schematics.
I have no idea where this happened during V5 development. The video demo
in the HEAD of the 5.1 branch shows the issue. All of the other demo cache
libraries are correct.

It's tempting to say that we don't need to exclude filename chars
from symbols, but we might regret that decision down the road. Better
to just escape them.

Loading the schematic symbol preserves the invalid LIB_ID characters in
the symbol name. Unfortunately, loading the library symbol automatically
fixes the invalid characters so this caused the symbol rescue to not find
library symbols with invalid characters. Replacing the invalid characters
in the schematic symbol name during rescue fixed the issue. This fix
isn't perfect because there is the off chance that replacing the invalid
characters could lead to a name clash in the library resulting in the
incorrect symbol to be rescued.

Apparently at some point in our development history, we allowed aliases
to be saved in the cache library. The rescue code was only looking for
root symbols in the cache library which caused missing symbol rescues.
Flattening the symbols ensures the rescue library will have a unique
symbol for every symbol in the schematic. This bug also was in play
when rescuing from the symbol library table.

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 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.
The code that checked for pin conflicts to determine if a symbol needed
rescued did not check either the pin convert setting so it was possible
for a pin from the other convert on symbols that do not have identical
units to appear to not have a pin conflict. Add tests for pin unit and
convert setting to prevent that from breaking the comparison. This must
have always been broken.
Fix the symbol preview widget to prevent drawing all symbols on top of
each other (if we need to do this the code will have to be revised) and
also show the convert if valid.
Fix broken symbol cache library when saving alias symbols.

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
crashing the connection graph refresh when running the project rescue
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.

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.
