Moved 'isPointer' attribute from variable to type field. The .types input file now includes new column specifying if a type is a pointer or not previously emugen declared as pointer only types which included '*' character but did not process well the case of 'char **' (pointer to pointer). Fixed the gl.types and ut_rendercontrol.types accordingly. Few other fixes to gl.attrib and gl.in. Change-Id: Ifd3591119dfa504703c68556802a40e38fe4940e
