This moves EESchema DLIST structures to rtree. These changes are more
fundamental than the pcbnew changes from 9163ac543888c01d11d1877d7c1
and 961b22d60 as eeschema operations were more dependent on passing
drawing list references around with SCH_ITEM* objects.
Changing the section like this in inline assembly
is not supported, and leads to issues because code
following the inline assembly macro ends up in the
wrong assembly section. This was causing linking
errors on gcc.
The files appear to be compiled so that the stack
isn't executable anyway, so we don't need to manually
create the section to say that.
