[truetype] Prevent bytecode reuse after the interpretation error. * src/truetype/ttinterp.c (free_buffer_in_size): New function to free the buffer allocated during the interpretation of this glyph. (TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if an error occurs in the bytecode interpretation. The interpretation of invalid bytecode may break the function definitions and referring them in later interpretation is danger. By unsetting these flags, `fpgm' and `prep' tables are executed again in next interpretation. Fix Savannah bug #30798, reported by Robert Swiecki.
