Implement shared IRQs using 'Irq_proxy' class. Nova: Added global worker 'Irq_thread' support in core and adapted Irq_session. FOC: Adapted IRQ session code, x86 has shared IRQ support, ARM uses the old model. Read and set 'mode' argument (from MADT) in 'Irq_session'. OKL4: Use generic 'Irq_proxy' Fixes issue #390
