The virtio-rng backend is currently linked twice, once in
virtio-rng-pci/virtio-rng-ccw and once in virtio-rng-device. This
causes a double unref of the backend when the parent device is unplugged.
To fix this, make virtio-rng-pci/virtio-rng-ccw use an alias, similar
to what is already being done

Passing the CPUARMState around in the decoder is a recipe for
bugs where we accidentally generate code that depends on CPU
state which isn't reflected in the TB flags. Stop doing this
and instead use DisasContext as a way to pass around those
bits of CPU state which are known to be safe to use.

This is a set of cleanup patches which avoid passing CPUARMState
around the decoder unnecessarily, since we were pretty much only
using it to check feature bits, which we now also have in the
DisasContext structure.
We still pass CPUARMState into disas_thumb_insn() and disas_thumb2_insn()

Instead of using IS_M(), use arm_dc_feature(s, ARM_FEATURE_M), so we

If the user neglects to specify the image format, QEMU probes the
image to guess it automatically, for convenience.
Relying on format probing is insecure for raw images (CVE-2008-2004).
If the guest writes a suitable header to the device, the next probe
will recognize a format chosen by the guest.
The meat is in PATCH 2. Its commit message could use even more
detail, but I want to get this out for discussion.
Prompted by the discussion we had back in August:

I have a somewhat related question, that perhaps someone may help me with:
Why isn't the qemu char driver/device interface based (for most devices)
on socketpair (and equivalent bi-directional pipe on other OS).
It looks to me like it could simplify API and event h
