[autofit] Make glyph style array use 16bit values. 

* include/freetype/ftautoh.h (FT_Prop_GlyphToScriptMap): Use
`FT_UShort' for `map' field.

* src/autofit/afglobal.c (af_face_globals_compute_style_coverage,
af_face_globals_new), src/autofit/hbshim.c, src/autofit/hbshim.h
(af_get_coverage): Use FT_UShort for `glyph_styles' array.

* src/autofit/afglobal.h (AF_STYLE_UNASSIGNED, AF_DIGIT): Extend to
16 bits.
(AF_FaceGlobalsRec): Use `FT_UShort' for `glyph_styles' field.
