Changes in v9:
  - Added `__rust_helper` prefixes to `ww_mutex.c`.
  - Reworked on Class to remove pinned initialization functions
    and added documentation suggesting its use as a global variable
    as this is its only usage on the C side.
  - Added myself as a maintainer of WW Mutex.
  - Various minor updates (commit description updates, minor code
    rearrangements, etc.).

Changes in v8:
  - Various minor updates (e.g., doc updates, removing unnecessary
    lifetime annotations, etc.).
  - Changed C implementation to always provide ww_class field in
    ww_mutex and ww_acquire_ctx types so we can access it from Rust
    easily.
  - Locking functions are now safe to call.
  - Added class validation logic to ww_mutex::lock_common.

Changes in v7:
  - Split Class and AcquireCtx into separate modules.
  - Removed "Ww" prefixes from type names.
  - Renamed exec.rs -> lock_set.rs and ExecContext -> LockSet.
  - Removed transmute logic from LockSet (formerly ExecContext).
  - Improved various doc-comments.
  - Marked certain AcquireCtx functions as unsafe.
  - Added from_raw constructors for Mutex, MutexGuard, AcquireCtx
    and Class.
  - LockSet::cleanup_on_deadlock no longer triggers reallocations when
    reinitializing AcquireCtx.
  - Incorporated various minor improvements suggested on the v6 series.

Changes in v6:
  - Added `unpinned_new` constructor for `WwClass` and updated
    global macros.
  - Changed all tests (and docs) to use Arc/KBox instead of
    `stack_pin_init` for `WwMutex` and `WwAcquireCtx`.
  - Added `LockKind` and `lock_common` helper to unify locking logic.
  - Added context-based and context-free locking functions for `WwMutex`.
  - Added `ww_mutex/exec` module, a high-level API with auto `EDEADLK`
    handling mechanism.

Changes in v5:
  - Addressed documentation review notes.
  - Removed `unwrap()`s in examples and KUnit tests.
