Let the compiler work out int size 

We have two places in the code where we pass a mutable parity integer
to ffi code. At one callsite we tell the compiler explicitly what type
it is (`::secp256k1_sys::types::c_int`) and at the other call site we
let the compiler figure out the type.

Is one way better than the other? I don't know. But letting the compiler
figure it out seems to make the code easier to read.
