Convert the use of 'struct twofish_ctx *' to 'void *' in prototypes of
functions which are referenced through 'struct common_glue_func_entry',
making their prototypes match those of this struct and, consequently,
turning them compatible with CFI requirements.
Whenever needed, cast 'void *' to 'struct twofish_ctx *'.
