Message:

Rewrite kernel mutex implementation a little

Removes MUTEX_ACTIVE, the use of which has been removed in favor of
irq_spinlock_t, and fixes some issues with the old implementation.

• A race in mtx→owner access is unavoidable, so make it explicitly atomic.
• The THREAD==NULL case happens when there are no other threads yet, so we factor it out as a special case. Also ensures recursive mutex works before threads are initialized, just as normal mutex does.
• More and better asserts.
