The current no-std implementation is somewhat ineffecient, potentially broken and relies on some slow data structures. The main reason why we use this implementation is because we don't have a way to "lock" the linked list, since there's no way to lock things in no-std. However, many embedded platforms have a concept of a "critical section" that can be used to exclusively lock something. This PR adds an option to the "std" implementation that replaces the existing Mutex with a usage of the critical-section crate. This is enabled with the "critical-section" feature. This allows us to have the advantages of the std-based implementation without needing to rely on std for platforms that don't have it. Signed-off-by: John Nunley <dev@notgull.net>
