1. Modified crates/spinlock to provide support for multiple backoff strategies when encountering lock contention, including exp-backoff. 2. Modified `BaseSpinLock` in crates/spinlock to support locking with a different guard/backoff type, providing more flexibility. 3. Added a new module `ruxrand` that aims to provide support for the usage of RNGs inside kernel. Currently a per-CPU RNG and support for rand-exp-backoff are implemented. 4. Changed the lock type used by `RunQueue`.
