Kernel: Add Thread::block_until(Condition).

Browse source 
Replace the class-based snooze alarm mechanism with a per-thread callback.
This makes it easy to block the current thread on an arbitrary condition:

    void SomeDevice::wait_for_irq() {
        m_interrupted = false;
        current->block_until([this] { return m_interrupted; });
    }
    void SomeDevice::handle_irq() {
        m_interrupted = true;
    }

Use this in the SB16 driver, and in NetworkTask :^)
