hw/m68k/next-cube: Add missing header comment to next-cube.h

The next-cube.h file is missing the usual copyright-and-license
header; add it (same as the next-cube.c one).

hw/m68k/next-cube: Make next_irq GPIO inputs to NEXT_PC device

Make the next_irq function be GPIO inputs to the NEXT_PC
device, rather than a freestanding set of qemu_irq lines.

This fixes a minor

hw/m68k/next-cube: Make next_irq GPIO inputs to NEXT_PC device

Make the next_irq function be GPIO inputs to the NEXT_PC
device, rather than a freestanding set of qemu_irq lines.

This fixes a minor Coverity issue where it correctly points
out the trivial memory leak of the memory allocated in the
call to qemu_allocate_irqs().

m68k: Add NeXTcube machine

It is still quite incomplete (no SCSI, no floppy emulation, no network,
etc.), but the firmware already shows up the debug monitor prompt in the
framebuffer display, so at least the very basics are already working.

This code has been taken from Bryce Lanham's GSoC 2011 NeXT branch at

https://github.com/blanham/qemu-NeXT/blob/next-cube/hw/next-cube.c

and altered quite a bit to fit the latest interface and coding conventions
of the current QEMU.
