Provides a single-point access for modifying the schematic and symbol
elements that allows chaining updates and reverting partial changes.
Standardizes the undo hierarchy between pcb and schematic editors
As this is another layer on the existing undo/redo structure, the
initial commit does not replace all undo/redo calls currently existing.
These will be handled in a series of follow-on commits
Before they were 1/2 treated as flags and 1/2 treated as a mode enum.
The ERC flag relaxes constraints on data that is settable in the
schematic editor.

Also fixes some plot bugs with arcs.
Also moves polygonization of arcs (when required) in plotting code
from 5 degrees to calculated based on ARC_HIGH_DEF.

It is no longer acceptable to set a LIB_FIELD index to -1. This was
trashing the sorting on load cause all kinds of false field comparison
failures. There are now assertions when attempting to use -1 as a field
index.

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.
It served us (mostly) well for more than a decade. It helped KiCad grow
before the std:: came into decent shape or speed. It was a good little
list.
