Our code for parsing this packet accidentally skipped the first of the two bytes of the signal value, because it started parsing the hex string at 'p + 1' when the preceding code had already moved past the 'C' or 'S' with "cur_action = *p++". This meant that we would only do the right thing for signals below 10, and would misinterpret the rest. For instance, when the debugger wants to send the process a SIGPROF (27 on x86-64) we mangle this into a SIGSEGV (11). Remove the accidental double increment.

Interrupt status is queried and controlled via the CPU's ipending and istatus registers. * The EIC (External Interrupt Controller) interface allows the CPU to connect to an external interrupt controller. The interface allows the interrupt controller to present a packet of information containing: - handler address - interrupt level - register set - NMI mode QEMU does not model an EIC currently. We do model the IIC, but its implementation is split across code in hw/nios2/cpu_pic.c and hw/intc/nios2_iic.c. The code in those two files has no state of its own -- the IIC state is in the Nios2CPU state struct. Because CPU objects now inherit (indirectly) from TYPE_DEVICE, they can have GPIO input lines themselves, so we can implement the IIC directly in the CPU object the same way that real hardware does. Create named "IRQ" GPIO inputs to the Nios2 CPU object, and make the only user of the IIC wire up directly to those instead. Note that the old code had an "NMI" concept which was entirely unused and also as far as I can see not architecturally correct, since only the EIC has a concept of an NMI. This fixes a Coverity-reported trivial memory leak of the IRQ array allocated in nios2_cpu_pic_init().
