* include/freetype/internal/ftserv.h (FT_FACE_FIND_SERVICE, 

FT_FACE_LOOKUP_SERVICE): Add parameter to pass pointer type.
Ugly, I know, but this is needed for compilation with C++ --
maybe someone knows a better solution?
Updated all callers.

* src/base/ftobjs.c (FT_Get_Name_Index, FT_Get_Glyph_Name): Remove
C++ compiler warnings.

* src/base/ftbdf.c (FT_Get_BDF_Charset_ID, FT_Get_BDF_Property):
Fix order of arguments passed to FT_FACE_FIND_SERVICE.

Avoid header files with identical names.
* include/freetype/internal/services/bdf.h: Renamed to...
* include/freetype/internal/services/svbdf.h: This.
