Porting Java's ConcurrentHashMap to Rust (part 1)

In this stream we begin the work of porting Java's ConcurrentHashMap to Rust. It will be a journey to get all the way there, but we got through most of the get, insert, and resize operations. Of particular note is the work required to go from the Java code's reliance on the garbage collector to Rust's runtime-free model.
