Factor out the FP_LIB_TABLE specific content from FP_TBL_MODEL into a new
LIB_TABLE_GRID class that can be used for any library table grid mix in.
Create new FP_LIB_TABLE_GRID object for the footprint library edit dialog.
Add method GetEnvVariables() to return any environment variables found in
a LIB_TABLE object.
Add SCH_PLUGIN object to PART_LIB object.
Convert all PART_LIB I/O to use SCH_PLUGIN.
Remove library caching from PART_LIB and use caching provided by SCH_PLUGIN.
Add support to use PROPERTIES for buffering and document file write control
instead of adding code the SCH_PLUGIN object in the SCH_LEGACY_PLUGIN that
will not be required when the new file formats are implemented.
Add buffering to SCH_LEGACY_PLUGIN to prevent cache from writing file on
every change to library. This is to prevent the cache library from being
written every time a new symbol is added.
Add option to not save library document file when saving library. This is
primarily used by the cache library write code.
Move symbol library write code out of LIB_PART and into SCH_LEGACY_PLUGIN.
Add exception handling where LIB_PART caught the exception and returned
an error status.
Remove KICAD_SCH_IO_MANAGER build option as it is no longer optional.
Rename FPID to LIB_ID as is now used as a generic library identifier and
is no longer specific to footprints.
Remove all mention of footprint from the new LIB_ID doxygen comments and
code.
Rename files fpid.h and fpid.cpp to lib_id.h and lib_id.cpp.
Rename fp_lib_table.keywords file to lib_table.keywords and adjust CMake
build dependencies accordingly.
Update all source files effected by the code and file name changes.
Update .gitignore for file name changes.
