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.

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.
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.

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.
Refactor rescue objects so that they can support derivation.
Factor out legacy rescuer code to perform legacy project rescues.
Create new symbol library table rescuer for rescuing symbol library table
based projects.
Perform the correct rescue type on project load.
Add symbol library table remapping support to the tools menu for run on
demand as applicable.
Add flag to SCH_SCREENS::UpdateSymbolLinks() to allow forcing the symbol
link updates when the library modification hash has not changed.
This commit was too broad and not cognizant of the purpose of the class
UTF8.
Add MAYBE_VERIFY_UTF8() macro, which can trap non-UTF8 encoded strings in
debug builds.
Use that macro conditionally in class UTF8 to trap non-UTF8 encoded strings
being put into UTF8 instances.
