Use NULL to trigger unassigned memory error on 32-bit accesses instead
of assert(0) as suggested by Blue Swirl.

This patch enhances the pcnet NIC emulation with better loopback mode
support, including CRC generation for looped-back packets in "raw" mode.
The patch has practically no impact on the normal RX and TX path.
Successfully tested against an ancient proprietary pcnet driver that
does a lot of hardware checks on boot-up and now works fine over qemu as
well.

This adds trivial support for the R2D-PLUS FPGA, mostly just for the
versioning information that the kernel uses for IRL mappings, in addition
to handling the heartbeat and poweroff writes.

Trivial patch adding CPU listing and the ability to do per-subtype
CVR/PVR/PRR values. Presently SH7750R and SH7751R definitions are
provided, as these are the ones in present use in-tree.
The CVR value for SH7751R is intentionally restricted so the kernel
boots, though this will want to be switched to the proper CVR value
once system emulation has sufficiently stabilized.
This also makes it trivial to abstract subtype specific registers like
MMU_PTEA and to set up feature bits in line with the kernel probing for
things like conditionalizing FPU/DSP context.

Trivial fix for a corner case: system_shutdown on isapc machines causes
qemu to segfaults due to accessing the uninitialized pm_state. Issue a
system shutdown instead.

- move do_interrupt() back to op_helper.c
- move non-helper prototypes from helper.h to exec.h
- move some prototypes from cpu.h to exec.h
- do not export either set_cwp() or cpu_set_cwp() from op_helper.c,
but instead provide inline functions
