This patch adds support for threaded IRQs and handlers through
irq::ThreadedRegistration and the irq::ThreadedHandler trait.
Threaded interrupts are more permissive in the sense that further
processing is possible in a kthread. This means that said execution takes
place outside of interrupt context, which is rather restrictive in many
ways.
Registering a threaded irq is dependent upon having an IrqRequest that
was previously allocated by a given device. This will be introduced in
subsequent patches.
