strange?

1. I extend ast_mutex_info:
	union {
+		pthread_mutex_t mutex;
+		pthread_rwlock_t rwlock;
+	};
and rename to ast_mutex_lock_info.

2. ast_mutex_lock_info used in typedef for ast_mutex_t:
+typedef struct ast_mutex_lock_info ast_mutex_t;
and ast_rwlock_t:
+typedef struct ast_mutex_lock_info ast_rwlock_t;

if DEBUG_THREAD is enabled.
