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 :^)
