Fix clang warnings. 

* src/gxvalid/gxvcmmn.h (GXV_SET_ERR_IF_PARANOID): Use 'do' block.
* src/gxvalid/gxvmod.c (GXV_TABLE_LOAD, GXV_TABLE_VALIDATE): Ditto.

* src/smooth/ftgrays.c (gray_convert_glyph): Add cast.

* src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Remove cast.
* src/type1/t1load.c (read_binay_data): Use `FT_ULong` for `size` parameter.
(parse_subrs, parse_charstrings, parse_dict): Ditto; also add some casts.
