Fix clang fixes. 

* src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate): Use
correct types.

* src/cff/cf2intrp.c (cf2_interpT2CharString) <default>: Force
unsigned for computations.
* src/cff/cffgload.c (cff_decoder_parse_charstrings): Ditto.
* src/cff/cffparse.c (cff_parse_integer): Ditto.

* src/psaux/t1decode.c (t1_decoder_parse_charstrings): Ditto.
