  Fix various memory problems found by linuxtesting.org.
  
  * src/base/ftgxval.c (FT_TrueTypeGX_Free, FT_ClassicKern_Free),
  src/base/ftotval.c (FT_OpenType_Free), src/base/ftpfr.c
  (ft_pfr_check): Check `face'.
  
  * src/base/ftobjs.c (FT_Get_Charmap_Index): Check `charmap' and
  `charmap->face'.
  (FT_Render_Glyph): Check `slot->face'.
  (FT_Get_SubGlyph_Info): Check `glyph->subglyphs'.
  
  Improve API documentation.
