  vl: add -object option to create QOM objects from the command line

This will create a new QOM object in the '/objects' path.  Note that properties
are set in order which allows for simple objects to be initialized entirely
with this option and then realized.

This option is roughly equivalent to -device but for things that are not
devices.

  rng-random: add an RNG backend that uses /dev/random (v3)

The filename can be overridden but it expects a non-blocking source of entropy.
A typical invocation would be:

qemu -object rng-random,id=rng0 -device virtio-rng-pci,rng=rng0

This can also be used with /dev/urandom by using the command line:

qemu -object rng-random,filename=/dev/urandom,id=rng0 \
     -device virtio-rng-pci,rng=rng0

  rng-egd: introduce EGD compliant RNG backend

This backend talks EGD to a CharDriverState.  A typical way to invoke this would
be:

qemu -chardev socket,host=localhost,port=1024,id=chr0 \
     -object rng-egd,chardev=chr0,id=egd0 \
     -device virtio-rng-pci,rng=egd0

  virtio-rng: hardware random number generator device

The Linux kernel already has a virtio-rng driver, this is the device
implementation.

When the guest asks for entropy from the virtio hwrng, it puts a buffer
in the vq.  We then put entropy into that buffer, and push it back to
the guest.

  virtio-rng: add rate limiting support

This adds parameters to virtio-rng-pci to allow rate limiting the entropy a
guest receives.  An example command line:

$ qemu -device virtio-rng-pci,max-bytes=1024,period=1000

Would limit entropy collection to 1Kb/s.

This allows you to specify:

  $ qemu -device virtio-rng-pci

And things will Just Work with a reasonable default.
