More 16bit fixes. 

* src/autohint/ahglobal.c (sort_values): Use FT_Pos for `swap'.
(ah_hinter_compute_widths): Use FT_Pos for `dist'.
Use AH_MAX_WIDTHS.
* src/autohint/ahglyph.c (ah_outline_scale_blue_edges): Use FT_Pos
for `delta'.
(ah_outline_compute_edges): Replace some ints with FT_Int and
FT_Pos.
(ah_test_extrema): Clean up code.
(ah_get_orientation): Use 4 FT_Int variables instead of FT_BBox to
hold indices.
* src/autohint/ahtypes.h (AH_SegmentRec): Change type of `score'
to FT_Pos.
