autofit: Fix some data types mismatching with their sources.
* src/autofit/afglobal.c: Correct the type of
AF_FaceGlobalsRec.glyph_count to match with
FT_Face->num_glyphs.
(af_face_globals_compute_script_coverage):
Insert explicit cast to compare
FT_Long AF_FaceGlobalsRec.glyph_count versus
FT_UInt gindex. The type of `nn' is changed
to scan glyph index upto AF_FaceGlobalsRec.glyph_count.
(af_face_globals_get_metrics): The type of `script_max'
is changed to cover size_t value. Insert explicit cast
to compare FT_Long AF_FaceGlobalsRec.glyph_count versus
FT_UInt gindex.
* src/autofit/afhints.c (af_axis_hints_new_segment):
Insert explicit cast to calculate `big_max' from
integer and size_t values.
(af_axis_hints_new_edge): Ditto.
* src/autofit/aflatin.c (af_latin_metrics_init_blues):
The type of `best_y' is matched to FT_Vector.y.
(af_latin_compute_stem_width): The type of `delta' is
matched to `dist' and `org_dist'.
