+ * The mutex usage verification code below aims to detect bad usage of
+ * Mbed TLS's mutex abstraction layer at runtime. Note that this is solely
+ * about the use of the mutex itself, not about checking whether the mutex
+ * correctly protects whatever it is supposed to protect.
+ *
+ * The normal usage of a mutex is:
+ * ```
+ * digraph mutex_states {
+ *   "UNINITIALIZED"; // the initial state
+ *   "IDLE";
+ *   "FREED";
+ *   "LOCKED";
+ *   "UNINITIALIZED" -> "IDLE" [label="init"];
+ *   "FREED" -> "IDLE" [label="init"];
+ *   "IDLE" -> "LOCKED" [label="lock"];
+ *   "LOCKED" -> "IDLE" [label="unlock"];
+ *   "IDLE" -> "FREED" [label="free"];
+ * }
+ * ```
+ *
+ * All bad transitions that can be unambiguously detected are reported.
+ * An attempt to use an uninitialized mutex cannot be detected in general
+ * since the memory content may happen to denote a valid state. For the same
+ * reason, a double init cannot be detected.
+ * All-bits-zero is the state of a freed mutex, which is distinct from an
+ * initialized mutex, so attempting to use zero-initialized memory as a mutex
+ * without calling the init function is detected.
+ *
+ * The framework attempts to detect missing calls to init and free by counting
+ * calls to init and free. If there are more calls to init than free, this
+ * means that a mutex is not being freed somewhere, which is a memory leak
+ * on platforms where a mutex consumes resources other than the
+ * mbedtls_threading_mutex_t object itself. If there are more calls to free
+ * than init, this indicates a missing init, which is likely to be detected
+ * by an attempt to lock the mutex as well. A limitation of this framework is
+ * that it cannot detect scenarios where there is exactly the same number of
+ * calls to init and free but the calls don't match. A bug like this is
+ * unlikely to happen uniformly throughout the whole test suite though.
+ *
+ * If an error is detected, this framework will report what happened and the
+ * test case will be marked as failed. Unfortunately, the error report cannot
+ * indicate the exact location of the problematic call. To locate the error,
+ * use a debugger and set a breakpoint on mbedtls_test_mutex_usage_error().
