This commit adds `into_inner` methods to the `Mutex`, `RwLock`, `spin::RwLock`, and `spin::Mutex` types, allowing the inner value to be extracted from the lock when the lock is owned exclusively. This seemed like a nice thing to add.
This commit adds `get_mut` methods to `Mutex`, `RwLock`, `spin::Mutex`, and `spin::RwLock`, allowing mutable access without locking when the lock itself can be accessed mutably. These are identical to the `std::sync::Mutex::get_mut` and `std::sync::RwLock::get_mut` methods.
This commit adds `Default` impls to `Mutex`, `RwLock`, and `spin::Mutex` where `T: Default`, allowing locked data to be constructed through `Default` without needing `Mutex::new(Default::default())` or similar. An implementation of `Default` for `spin::RwLock` was not added, because I already did that in #472.
