Tamir Duberstein 210b81578e rust: xarray: Add an abstraction for XArray ...

`XArray` is an efficient sparse array of pointers. Add a Rust
abstraction for this type.

This implementation bounds the element type on `ForeignOwnable` and
requires explicit locking for all operations. Future work may leverage
RCU to enable lockless operation.
