* include/freetype/config/ftconfig.h: Use CHAR_BIT to define 

size of FT_SIZEOF_xxx.


* include/freetype/internal/sfnt.h (TT_Find_SBit_Image_Func,
TT_Load_SBit_Metrics_Func): New typedefs.
(SFNT_Interface): Add find_sbit_image and load_sbit_metrics.

* src/sfnt/sfdriver.c (sfnt_interface): Updated.
* src/sfnt/ttsbit.h (tt_find_sbit_image, tt_load_sbit_metrics): New
declarations.
* src/sfnt/ttsbit.c (find_sbit_image): Renamed to...
(tt_find_sbit_image): This.
Updated all callers.
(load_sbit_metrics): Renamed to...
(tt_load_sbit_metrics): This.
Updated all callers.
