Arguments of `arf_mul_2exp_si`: mutability

[Chris00]

The header file arf.h declares

ARF_INLINE void
arf_mul_2exp_si(arf_t y, const arf_t x, slong e)

I therefore do not understand by the second argument of arb_sys::arf::arf_mul_2exp_si is mutable:

pub unsafe extern "C" fn arf_mul_2exp_si(
    y: *mut arf_struct, 
    x: *mut arf_struct, 
    e: mp_limb_signed_t
)

The bindings are auto generated using rust-bindgen which for some reason doesn't notice some arguments should be const and instead makes them mutable. So far I've been manually correcting them but I plan on asking the bindgen people about it.

Feel free to correct the bindings in arf.rs and make a pull request if you would like it fixed right away, otherwise I will get to it when I can.

The same is true for arf_printd:

ARF_INLINE void
arf_printd(const arf_t y, slong d)

v.s.

pub unsafe extern "C" fn arf_printd(
    y: *mut arf_struct, 
    d: mp_limb_signed_t
)

I will.

It seems the issue is known and unresolved at rust-bindgen. See the mention above.
