Message : Fix some FreeType Coverity issues as reported for Ghostscript. * src/base/ftobjs.c (FT_New_Face, FT_New_Memory_Face): Initialize `args.stream' (#3874, #3875). (open_face_PS_from_sfnt_stream): Improve error management (#3786). * src/base/ftmm.c (ft_face_get_mm_service): Fix check of `aservice' (#3870). * src/base/ftstroke.c (ft_stroke_border_get_counts): Remove dead code (#3790). * src/base/ftrfork.c (raccess_guess_apple_generic): Check error value of `FT_Stream_Skip' (#3784). * src/type1/t1gload.c (T1_Load_Glyph): Check `size' before accessing it (#3872) * src/pcf/pcfdrivr.c (PCF_Glyph_Load): Check `face' before accessing it (#3871). * src/pcf/pcfread.c (pcf_get_metrics): Handle return value of `pcf_get_metric' (#3789, #3782). (pcf_get_properties): Use FT_STREAM_SKIP (#3783). * src/cache/ftcmanag.c (FTC_Manager_RegisterCache): Fix check of `acache' (#3797) * src/cff/cffdrivr.c (cff_ps_get_font_info): Fix check of `cff' (#3796). * src/cff/cffgload.c (cff_decoder_prepare): Check `size' (#3795). * src/cff/cffload.c (cff_index_get_pointers): Add comment (#3794). * src/bdf/bdflib.c (_bdf_add_property): Check `fp->value.atom' (#3793). (_bdf_parse_start): Add comment (#3792). * src/raster/ftraster.c (Finalize_Profile_Table): Check `ras.fProfile' (#3791). * src/sfnt/ttsbit.c (Load_SBit_Image): Use FT_STREAM_SKIP (#3785). * src/gzip/ftgzip.c (ft_gzip_get_uncompressed_size): Properly ignore seek error (#3781).
