1da2738f55 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

5c74521d24 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
