Fix clang warnings.

* src/autofit/aflatin.c (af_latin_hints_compute_segments): Use
FT_UShort for `min_flags' and `max_flags'.
Initialize `prev_*' variables.

* src/cff/cffobjs.c (cff_face_init) [FT_DEBUG_LEVEL_TRACE]: Fix
types of local variables.

* src/smooth/ftgrays.c (gray_dump_cells) [FT_DEBUG_LEVEL_TRACE]:
Update `printf' format string.

* src/tools/ftfuzzer/ftfuzzer.cc (setIntermediateAxis): Add cast.
(LLVMFuzzerTestOneInput): Fix loop type.
