Josh Holtrop 9696cf26eb Rust wrapper: use Rc instead of Arc for RNG references 
WC_RNG has no internal locking so it is not safe to share a single
WC_RNG across threads without locking.

Josh Holtrop 54cb1d8d38 Rust wrapper: ensure memory safety for C RNG struct 
- store pointer to WC_RNG instead of full struct
- enforce RNG is not dropped before consumer structs

The C library stores a pointer via the set_rng() methods on a few
structs (e.g. RSA). This change holds a reference (or instance) of RNG
within the consumer structs to ensure it is kept alive if set_rng (or
now set_shared_rng) is used.
