* src/type1/t1load.c (parse_subrs, parse_charstrings): Use decrypt 

function from PSAux module.

* src/type1/t1parse.c (T1_Done_Parse): Renamed to...
(T1_Finalize_Parser): New function (to avoid name clash with a
function in the PSAux module).
(T1_Decrypt): Removed since it it duplicated in the PSAux module.
(T1_Get_Private_Dict): Added `psaux' as new parameter; use decrypt
function from PSAux module.

* src/type1/t1parse.h: Adapted.
