Message:

Use recursive mutex to protect task_t::cap_info

This makes it possible to use the mutex-protected capability APIs even
inside caps_apply_to_kobject_type() callbacks. Now there is no need to
provide eg. cap_unpublish_locked() and cap_free_locked(). Likewise,
ipc_irq_unsubscribe() can be used when the task's cap_info is already
locked by the current thread inside of a callback.
