Fix compiler warnings.
Reported by Wojciech Mamrak <[email protected]>.

* src/autofit/afglobal.c (af_face_globals_compute_style_coverage),
src/autofit/afmodule.c (af_property_set): Fix `signed' vs.
`unsigned' issues.

* src/autofit/aflatin.c (af_latin_metrics_init_blues): Make compiler
happy.

* src/base/ftlcdfil.c (_ft_lcd_filter_fir): Use only four elements
for `fir'.
Fix `signed' vs. `unsigned' issues.

* src/sfnt/sfobjs.c (WRITE_BYTE): Removed, unused.
(WRITE_USHORT, WRITE_ULONG): Add proper casts.

* src/truetype/ttgload.c (TT_Get_VMetrics): Add proper casts.

* src/truetype/ttinterp.c (Ins_DELTAP): Add proper casts for `B1'
and `B2'.
