* include/freetype/internal/ftobjs.h: Don't include
FT_CONFIG_STANDARD_LIBRARY_H.
(FT_Validator, FT_VAlidationLevel, FT_ValidatorRec, FT_VALIDATOR,
ft_validator_init, ft_validator_run, ft_validator_error, FT_INVALID,
FT_INVALID_TOO_SHORT, FT_INVALID_OFFSET, FT_INVALID_FORMAT,
FT_INVALID_GLYPH_ID, FT_INVALID_DATA): Move to...
* include/freetype/internal/ftvalid.h: New file.
Make FT_INVALID return module-specific error codes.
* include/freetype/internal/internal.h (FT_INTERNAL_VALIDATE_H): New
macro.
* include/freetype/fterrors.h: Undefine FT_ERR_PREFIX only if
FT_KEEP_ERR_PREFIX isn't defined.
* src/base/ftobjs.c: Include FT_INTERNAL_VALIDATE_H.
* src/sfnt/ttcmap.h: Don't include FT_INTERNAL_OBJECTS_H but
FT_INTERNAL_VALIDATE_H.
* src/sfnt/ttcmap.c: Don't include FT_INTERNAL_OBJECTS_H but
FT_INTERNAL_VALIDATE_H.
Include sferrors.h before FT_INTERNAL_VALIDATE_H.
s/FT_Err_Ok/SFNT_Err_Ok/.
* src/sfnt/sferrors.h: Define FT_KEEP_ERR_PREFIX.
* src/type1/t1afm.c: Include t1errors.h.
