pango/opentype/ftxopenf.h: In Load_ChainContextSubst2,
handle the case where an empty class definition
is represented by an offset of 0.
* pango/opentype/ftxgpos.c: Same for Load_ChainContextPos2.
* pango/opentype/{ftxopen.c,ftxgpos.c,ftxgsub.c,ftgdef.c}:
Fix pervasive bug where on cleanups on failure of loading
an array element, all array elements were freed, not
just the ones that had been succesfully loaded.
