Merge #1870
1870: mmap addr r=asomers a=JonathanWoollett-Light
Uses `Some<size_t>` instead of `*mut c_void` for the `addr` passed to [`sys::mman::mmap`](https://docs.rs/nix/latest/nix/sys/mman/fn.mmap.html).
In this instance we are not usefully passing a pointer, it will never be dereferenced. We are passing a location which represents where to attach the shared memory to.
In this case `size_t` better represents an address and not a pointer, and `Option<size_t>` better represents an optional argument than `NULLPTR`.
In C since there is no optional type this is a pointer as this allows it be null which is an alias here for `None`.
