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.
When placing a new component in the schematic, this allows the user to
iterate through all units in the selected component without re-opening
the choose part dialog. It also allows the optional addition of
multiple copies of the same component to be placed in the schematic.

It was confusing that the primary frames registered their tools
differently than the other frames. In addition, since the other
frames also added their own tools, foo_actions::RegisterAllTools()
didn't really register all tool but rather those used by the
principal frame (PCB_EDIT_FRAME, SCH_EDIT_FRAME, etc.)

The canvas type might change without the frame being notified. If this
happens, the user is presented with repeated notifications of OpenGL
issues. Howver, switching canvas is not an error and should be
presented to the user as an info message to clarify that the system is
still working but it has changed how it renders the screen.

This makes using Scrollbars more easy to use, especially for "small" page sizes like A or B.
Note also the working/drawing area size is bigger than the page size (3 times)
Center point of a block may not always be located on a grid point,
therefore it needs to be rounded to the grid size to prevent off grid
component placement.
