Fix build error when KICAD_USE_SCH_IO_MANAGER=OFF due to const issues with
LIB_PART ctor.
Fix unused variable build warning in legacy schematic plugin.
Make LIB_PART copy constructor take a const LIB_PART reference.
Add SaveSymbol to legacy symbol library plugin.
Add removeAlias to legacy symbol library cache.
Add AddSymbol to legacy symbol library cache.
* Write SCH_LEGACY_PLUGIN_CACHE object for handling the legacy symbol library
file format.
* Write legacy symbol library file parser.
* Write code to transfer cache to PART_LIB object so existing library save
code can be used for round trip testing. This is temporary until Eeschema
is updated to use the plugin for library management rather than PART_LIB.
* Add LIB_XXXX object helper functions where there was no way to set the member
variables of an object.
* Give the cache object friend status to some object where there are incredibly
byzantine ways of setting text in LIB_XXXX objects.
* Add SCH_PLUGIN::Save() for current file format and code for saving all
SCH_XXX objects.
* Add function to SCH_FIELD to get the position of the field in the component
not the position added to the component position which is what GetPosition()
does. This was required because saving the component field expects position
of the field sans the position of the component.
* Remove public members from BITMAP_BASE object and fix all associated
code.
* Fix the never ending coding policy violations found making these changes.
* Create a new dummy root sheet and screen when the schematic fails to load
which was causing Eeschema to crash.
* Remove conversion from UTF8 to wxString left over from a previous change
which hopefully will fix an OSX build error.
* Fix parsing of text objects to handle version 1 schematic files.
* Fix parsing of component fields to handle version 1 schematic files.
* Don't throw a parse error when a version 1 schematic file doesn't end with
$EndSCHEMATC.
* Factor out PROPERTIES object from the PCB plugin code and move it into
common so it can be used by both the Pcbnew and Eeschema plugins.
* Add schematic I/O plugin manager for loading and saving schematic and
component library files.
* Add initial attempt at a parser for current schematic file format. This
parser will be infinitely more strict than the current parser which is very
forgiving in what it parses.
* Make minor changes to the base bitmap class to support the new parser.
* Add find root sheet support to sheet object to allow fetching the root
sheet from any sheet in the stack.
