+ XXX_cmap_encoding_char_next() return FT_UInt32 values.

+ matched with its input charcode value.
+
+ * src/cff/cffmap.c (cff_cmap_encoding_char_next,

+
+ * src/psaux/t1cmap.c (t1_cmap_std_char_next,

+ tt_cmap12_char_next, tt_cmap13_char_next): Ditto.
+ (tt_cmap14_char_variants): Handle base unicode
+ codepoint by FT_UInt32 variable to avoid overflow
+ on 16-bit platforms.
+ (tt_cmap14_ensure): The type of `num_results' is
+ extend to FT_UInt32, to cover unsigned 32-bit
+ `numVarSelectorRecords' in cmap14 table header.
